Antioxidant activity and inhibitory effect on oxidative DNA damage of ethyl acetate fractions extracted from Cone of Red Pine (Pinus densiflora) were investigated to find utilization of Cone, by-product of Red Pine, thrown out after berry shatter, as a new natural plant resource. Cone from P. densiflora was extracted with methanol (MeOH) and separated to petroleum ether, ethyl acetate and water fraction. Among them, ethyl acetate fraction was used. The antioxidant activity was conducted by the 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical, 2, 2'-Azino-bis (3-ethylbenzothiazoline-6 sulfonic acid) diammonium salt (ABTS) radical scavenging assay, Fe 2+ chelating assay and reducing power assay. The inhibitory effect on oxidative DNA damage was determined by DNA cleavage assay using φX-174 RF I plasmid. The results of DPPH and ABTS radical scavenging activity at 200 ㎍/㎖ of extracts were 86.50% and 95.80% respectively, which were similar figures compared with L-ascorbic acid as control. Fe 2+ chelating activity was 77.96% and reducing power was 0.77 at 200 ㎍/㎖. Total phenolic component was 27.29±0.3 ㎎/g and Vitamin C content was 1.84±0.1 ㎎/g. Also ethyl acetate fraction from Cone has inhibitory effect, using φX-174 RF I plasmid on DNA cleavage assay. In conclusion, Cone, by-product of P. densiflora, showed high antioxidant activity and inhibitory effect on oxidative DNA damage. Therefore this study suggests Cone, useless by-product, can be developed as a new natural plant resource with lots of utilization such as an effective antioxidant, natural medicine, food, cosmetics and so on.

This study is focused on the evaluation of growth parameters, total polyphenol content (TPC), chlorophyll content as well as the DPPH (1,1-diphenyl-2-picryhydrazyl) free radical scavenging activity of young barley seedling (YBS) affected by elicitation. Salicylic acid (SA), methyl jasmonate (MJ), amino acid liquid fertilizer (ALF) and microbial metabolism activator (MMA) were used. Elicitation was conducted for two times and various concentrations were used in this study. The result revealed that, MJ 1 ml/L treated-YBS gave the longest seedling length of 1.33 cm, followed by the ones treated with SA 1.38 mg/L and ALF 2 ml/L, respectively. ALF 3 ml/L treatment gave the highest fresh weight of 10 seedlings, followed by MJ 5 ml/L and SA 13.8 mg/L treatment with 1.56 g, 1.55 g and 1.53 g respectively. SA 138.12 mg/L elicitor treated-YBS gave the highest Chl a, Chl b content of 8.57 μg/mg and 3.83 μg/mg, respectively while the highest carotenoid content was found in MJ ml/L treatment with 1.62 μg/mg. Among elicitor treated-YBS, SA showed better TPC. The highest TPC was found in SA 1.38 mg/L treatment with 18.82 mg/g TAE. Likewise, SA 1.38 mg/L showed the highest DPPH free radical scavenging activity among all the treatments. However, the lowest TPC was found in ALF 1ml/L treated-YBS with 9.46 mg/g TAE, which was even lower than the control (14.31 mg/g TAE).

The purpose of this study was to improve the functionality of a healthy drink with examining the possibility of manufacturing different enzymes (alpha-, beta-, glucose-amylase) in barley malts (BM) produced in various malting periods. The study showed that enzyme treatment increased significantly total polyphenol content (TPC), DPPH radical scavenging activity and hydroxly radical scavenging activity in malted liquid samples (MLS) which obtained from various malting periods. The highest of TPC were found in Gluco-24M with 1.981 ㎎TAE/㎖, followed by Beta-24M and Alpha-72M with 1.878 ㎎TAE/㎖ and 1.845 ㎎TAE/㎖, respectively. The DPPH result revealed that percent of inhibition increased by 71-75% compared to the control. No statistical difference was found between MLS obtained by 24 hr of malting (24 M) and 72 hr of malting (72 M) after enzyme treatment. In addition, an increasing of hydroxyl radical was in the same trend to the TPC and DPPH. The hydroxyl radical scavenging activity of enzyme treated samples was 1,5 times higher than the control. These results suggest the possibility of enzyme application to barley malts obtained in various germination periods for improving quality and functionality of barley malts.

Drynariae rhizoma (64.67%) obtained higher DPPH radical scavenging activity compared to Achyranthis radix (19.03%). Similar results were obtained in the reducing power. No differences were observed on the ABTS radical scavenging ability and SOD. In contrast, Achyranthis radix (77.60%) has higher chelating ability compared to Drynariae rhizoma (46.21%). In vivo experiments revealed higher plasma TBARS in OVX-DR than in OVX-AR. Opposite result was seen in erythrocyte TBARS. Hepatic, nephritic and erythrocyte enzymes were considered for the antioxidant enzyme activities. GSH-Px and PON of hepatic enzymes were higher in OVX-AR. While the CAT and GR were higher in OVX-DR. SOD, GSH-Px, GR and PON of nephritic enzymes of OVX-DR were higher compared to OVX-AR. Almost similar values were obtained in CAT using both extracts. The OVX treated rats obtained higher CAT and GR in the erythrocyte enzymes compared to SHAM. The SOD of erythrocyte enzymes in OVX-DR was higher compared to OVX-AR. On the other hand, the GSH-Px was higher in OVX-AR.

This study was conducted to clarify the antimicrobial effect, antioxidant and tyrosinase inhibitory activities of the biological composition having the Phytolacca americana, and to enhance the natural materials utilization of foods and cosmetics. The antimicrobial activities of the different parts of P. americana were evaluated using the agar diffusion test. The antimicrobial activity of P. americana was relatively high in Malassezia furfur known as a skin fungi and Vibrio parahaemolyticus compared to Escherichia coli and Staphylococcus epidermidis. However, the antimicrobial activity in Vibrio parahaemolyticus did not show at all parts of P. americana. Both the DPPH radical scavenging activity and ABTS radical scavenging activity have been increased with the higher concentration of methanol extract. In particular, leaf extract of P. americana exhibited the highest activity both ABTS radical scavenging activity and DPPH radical scavenging activity. The nitrite scavenging activity was decreased when the pH was changed from pH 1.2 to pH 6.0. The highest nitrite scavenging activity was exhibited from the methanol extract of fruit, followed by root, stem, and leaf at pH 1.2. However, the nitrite scavenging activity at pH of 6.0 was not almost detected. All plant parts of P. americana showed tyrosinase inhibitory activity. The highest activity was found in the stem, and followed by root, leaf, and fruit in order. These tyrosinase inhibitory activity was progressively increased in a concentration-dependent manner. In this experiment on the methanol extracts of different organ from P. americana, we confirmed that the extract of P. americana showed potent tyrosinase inhibitory activity. Taken together, we conjectured that the P. americana had the potent biological activities, therefore this plant having various functional components could be a good material for development into source of natural food additives and cosmetics

본 연구에서는 부재료를 첨가하지 않는 건 블루베리를 제조기술을 확립하고자 건조 온도를 달리하여 건 블루베리의 품질변화와 항산화 특성을 조사하였다. 즉, 건 블루베리 제조는 건조 온도에 따라 A(40℃, 72시간), B(40℃, 48시간 및 50℃, 24시간), C(50℃, 72시간), D(60℃, 72시간)로 하였다. 건 블루베리의 수율을 측정한 결과 17.73~31.17%의 범위이었으며 건조 온도가 낮을수록 유의적으로 높게 나타났다(p<0.05). pH는 A가 가장 높았으며 가용성 고형분 함량은 건조 온도가 높을수록 유의적으로 높아지는 것으로 나타났다(p<0.05). 수분함량 및 수분활성도는 건조 온도가 높을수록 낮아지는 경향으로 나타났다. 색도를 측정한 결과 L값은 건조 온도가 낮은 A가 높게 나타난 반면 a값 및 b값의 경우는 건조 온도가 높은 D가 높게 나타났다. 건조된 건 블루베리의 색도는 건조 온도가 높을수록 건조는 빨리 되었지만 육안으로 보았을 때 과피의 색이 주황색으로 변하여 상품으로 적절하지 않았다. 조직감 변화는 경도(hardness), 점성(gumminess) 및 씹힘성(chewiness)은 건조 온도가 높을수록 높은 값을 나타내었으며 탄력성(springiness)과 응집성(cohesiveness)은 비슷한 경향으로 건조 온도가 높을수록 약간 증가하는 경향이었지만 유의적인 차이는 없었다(p<0.05). 관능적 특성에서 전반적인 기호도는 B > A > C > D순으로 평가되었다. 항산화 특성으로 총 폴리페놀 함량과 DPPH radical 소거능을 측정한 결과 건조 온도가 낮을수록 항산화 활성이 높게 나타났다. 따라서 건 블루베리 제조에 적당한 처리군은 B로 열풍건조 온도를 40℃로 하여 48시간 건조 후 온도를 50℃로 높여 24시간 동안 건조하는 것이 품질이 우수한 상품과 형성율을 높이는데 좋을 것으로 생각된다.

Grain color distinguishes between the pigmentation of the outer layer of the kernel. It is known that environmental factors affects the production of anthocyanins and abiotic stresses like high light intensity, low temperature, high salinity and/or drought stress, and others increase their amounts. After 7 days the germination rate between yellow and dark-purple seeds were almost the same with and without stress (100% yellow seeds under stress and without stress germinated, 93.3% under stress and 96.6% without stress of purple seeds germinated), even though at the final stage the germination was almost the same, we can conclude base on our observations that the germination takes place at a different rate. We think that this might be related to the seed color, since the germination of purple seeds under salt stress started earlier than the yellow ones, until both reached the same point. The antioxidant activity was higher in seedlings from dark-purple seeds than the yellow ones, and they were higher under salt stress than without it, supporting our hypothesis that the purple color in wheat seeds works as a protection under salt stress. Furthermore, the qRT-pCR showed that some genes related to the flavonoid pathway were expressed or had more expression in the seedlings from dark-purple seeds than yellow ones.

Flavonoids and total polyphenols are important secondary plant metabolites, as they play a role in reducing the oxidative stress caused by ROS In this study, we investigated for flavonoid contents, total polyphenol contents, and antioxidant activities in 27 accessions from 10 Vicia species. Among 27 vicia accessions, NAC17 (V. monantha) and NAC14 (V. hyrcanica) had the highest total flavonoid (1.42 ± 0.09 mg/g) and total polyphenol (124.2 ± 0.5 μg/GAE mg) contents, respectively. In four flavonoids, naringenin showed the highest concentrations in Vicia species. The DPPH and ABTS were the range from 0.2 (NAC24, V. sativa subsp. nigra) to 18.5 (NAC13, V. faba) μg/ASC mg and 19.1 (NAC7, V. cracca) to 253.4 (NAC13, V. faba) μg/Trolox mg, respectively. Among the 10 Vicia species, V. monantha and V. hyrcanica had the highest flavonoid (1.31 ± 0.09 mg/g) and total polyphenol (116.5 ± 2.0 μg/GAE mg) contents, respectively. The highest antioxidant activity was detected in V. faba. These results will expand the flavonoid database and provide information on Vicia species valuable for development of functional foods or feed-additives resources.

Total phenol, flavonoid and antioxidant components of cabbage leaf samples derived from different cultivar were determined. Total phenol compound content showed the highest amount in methanol extracts from ‘YR Howol’ cultivar (11.72 ㎎/g), followed by ‘Harutame’ (10.66㎎/g), ‘Winstar’ (10.34 ㎎/g) and YR Hero (10.20 ㎎/g). The highest amount of total flavonoid content was observed from the methanol extracts of Harutame (5.39 ㎎/g), followed by Winstar (4.28 ㎎/g), Wialhowol (4.10 ㎎/g). The SOD enzyme activity showed a high activity of ‘YR Hogeo’ cultivar, and the cultivar of ‘YR Howol’ cultivar showed the lowest activity of SOD. The activity of CAT and APX showed higher values ‘Ogane’ and ‘YR Hogeol’ cultivars than the other cultivars. The POD activities showed relatively high values ‘Ogane’ and ‘YR Howol’ cultivars compared with other cultivars. The free radical (DPPH) scavenging activity showed lower IC50 values of ‘Harutame’ (15.71) and ‘YR Howol’ cultivar (16.88), however methanol extract of ‘YR Hero’ cultivar (22.49) being the highest. The extracts of all cabbage cultivars in the reaction solution of pH 1.2 could be decomposed nitrite more than 50%. Especially, the cultivar ‘YR Hogeol’ and ‘Ogane’ showed a relatively high nitrite scavenging activity for each 60.13% and 57.20% respectively. The IC50 values of antioxidant activity determined by ABTS were lower in ‘Harutame’ (17.04) and ‘YR Howol’ cultivar (17.97), and its results observed similar with values obtained from the same extracts by DPPH method. The result of this study suggests that the methanol extract of Brassica oleracea L. contains the high amount of phenolic and higher radical scavenging activities.

This experiment was conducted to obtain the have higher contents of pharmaceutical constituents as well as higher yield from colchicine induced diploid and tetraploid extracts of Platycodon grandiflorum. In order to determine the biological activity, this study was focused to evaluate the cytotoxicity, antimicrobial on the bronthus disease bacteria, antioxidant enzyme activity of diploid and tetraploid extracts in P. grandiflorum. The activities of antioxidant enzyme according to different solvent extracts were measured as superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and ascorbate peroxidase (APX). The cytotoxicity of methanol extracts of P. grandiflorum showed significant differences between tetraploid and diploid. That is, the cytotoxic effect against human cancer cell was higher in tetraploid than in diploid. At all extracts concentration, tetraploid samples showed high toxicity and the IC50 (concentration causing 50% cell death) value showed the highest on HCT-116 cell (105.91 μg/mL), and exhibited significant activity against the Hep 3B cell (140.67 μg/mL), SNU-1066 cell (154.01 μg/mL), Hela cell (158.37 μg/mL), SNU-601 cell (182.67 μg/mL), Calu-6 cell (190.42 μg/mL), MCF-7 cell (510.19 μg/mL). Antimicrobial activities of diploid P. grandiflorum were relatively low compared to tetraploid P. grandiflorum on most of the bacterial strains. In tetraploid P. grandiflorum, K. pneumoniae showed the clear zone formation (18~19 mm) of growth inhibition, followed by the clear zone formation of 13~15 mm on C. diphtheria and S. pyogenes. The antimicrobial activities in diploid P. grandiflorum were the highest on K. pneumonia (14~15 mm), and showed the clear zone formation of 11~12 mm on C. diphtheria and 12~13 mm on S. pyogenes. The antimicrobial activity is thought to look different depending on the bacterial strains and the polyploidy of P. grandiflorum. The root extract of P. grandiflorum had the highest (97.2%) SOD enzyme activity in ethyl acetate partition layer of tetraploid while water partition layer of diploid showed the lowest (48.6%) SOD enzyme activity. The activity of CAT showed higher values in the root of tetraploid than in the diploid of P. grandiflorum in all partition layers except butyl alcohol. The activities of APX and POD showed higher values in the root of tetraploid than in the diploid of P. grandiflorum in all fraction solvents except water layer. These results indicate that the tetraploid P. grandiflorum can be used as a source for developing cytotoxic agent and antimicrobials which can act against bronchus diseases bacterial strains.

A total of CNU 28 colored hybrids developed at the Chungnam National University were evaluated to identify new cultivars with functionality.
