Backgrounds : Camellia sinensis is known to have a very high antioxidant activity, but its petals are small and it is difficult to use it because of its low yield. In comparison Camellia japonica has many petals and yield, however, the biological effects of C. japonica have been less frequently studied. In the present study, we focused on investigating the in vitro antioxidant effect of the ethanol extract from flower of C. sinensis (CSF), C. japonica (CJF) and mixture of CSF and CJF. Methods and Results : Content of total phenolics and total flavonid, DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activities, reducing power, superoxide anion and hydroxy radical scavenging activity of CSF and CJF were compared in vitro experimetal models. Total phenolics was contained the higer in CJF (172.19±1.65 mgCAE/gEX) than 146.75±0.15 mgCAE/gEX in CSF. And effects of antioxidant measured by reducing power, superoxide anion generated by xanthine/xanthine oxidase and hydroxyl radical generated by the Fenton reaction (FeSO4 + H2O2) in a cell-free system was shown higher in mixture of CSF and CJF than BHT, ascorbic acid as a chemical oxidant which was detected by electron spin resonance spectrometry coupled with DMPO spin trapping. These results suggest that Camellia flower extract such as CSF and CJF exhibits antioxidant properties by scavenging ROS. Camellia extract contained quercetin, quercetin-3-O-glucoside, quercitrin and kaempferol, which are antioxidant compounds. Conclusion : As a result, the combination of CSF and CJF showed higher antioxidative effect than using CSF or CJF alone.

Background : Plants are the rich source of antioxidants, which plays a very important role in maintaining human health. Their antioxidant property protects cells of different organs of human beings against free radicals and free radical mediated diseases. Even though, there is lack of knowledge on the antioxidant effect of lutein present in plants. In the present study, lutein was isolated from the GreenTea leaves (Camellia sinensis) which is used as a dietary source. Methods and Results : The procedure adopted for the isolation and purification of lutein using acetone extraction and preparative high performance liquid chromatography (HPLC) is simple and less time consuming. Free radicals scavenging activity of isolated lutein from acetone extract of GreenTea was assessed by DPPH radical scavenging assay and reducing power. The isolated lutein scavenged 79% of DPPH radicals at 20 ㎍/㎖ and two fold lower concentration compared to the standard antioxidants (α-tocopherol). No significant differences were found between the reducing power of the lutein and BHT when their concentrations were high. However, significant differences were observed at relatively low concentrations, the reducing power of lutein was isolated from the GreenTea leaves was stronger than those of their acetone extract and standard antioxidants (BHA). Both electron spin resonance (ESR) and in vitro assay confirmed that lutein was isolated from the GreenTea leaves, exhibited a greater capacity for scavenging superoxide (O2 •－) and hydroxyl (OH •) radicals than standard antioxidants β-carotene and α-tocopherol respectively. Conclusion : The results proven that lutein isolated from GreenTea leaves has an efficient antioxidant ability, it could serve as an antioxidant to scavenge reactive oxygen species.

Background : Lutein, a xanthophyll, consists of chains with 8 conjugated double bounds containing closed rings on each end of the chain. This carotenoid is found in fruits and vegetables, especially dark green leafy vegetables such as green tea. In this study, we investigated the anticancer effects of purified lutein from green tea on human cancer cell lines containing prostate carcinoma cancer cells (LNCaP). Methods and Results : Prostate carcinoma cancer cells (LNCaP) were cultured and evaluated the inhibitory effect of lutein isolated from green tea compared other carotenoids (β-carotene and lycopene) on cell proliferation. Cyclin D1 and PCNA were evaluated as cell differentiation. In results, PCNA/cyclin regulates the initiation of cell proliferation by mediating DNA polymerase. Under cultural conditions, lycopene remarkably suppressed the PCNA expression prostate cancer cell line LNCaP in higher doses (20 μM - 100 μM) statistically. However, β-carotene and lutein presented the less inhibitory effects on PCNA expression. Determination of PCNA expression in control and treated cells demonstrates that lycopene did affect proliferation in LNCaP cancer cells in dose-dependent manner. However, β-carotene and lutein suppressed the cyclin D1 expression in dose-dependent manner but no in lycopene group. These results indicate that differ carotenoids presented the various suppressive ability of PCNA and cyclin D1 expression in cell proliferation. Conclusion : In conclusion, lutein suppressed the carcinogenesis of induced prostate cancer cell line by acting as a suppressor for inhibiting the expression of cyclin D.

Background : The objective of this study was to investigate antioxidant activities, inhibitory activities against heme induced colonic epithelial cell proliferations, anti-inflammatory activities and anthocyanin profiles in the anthocyanin rich fraction (ARFAM) from fruits of Aronia melanocarpa, where these are considered functional substances and available food coloring agents in Korea. Methods and Results : Anthocyanins were identified by reversed-phase C18 column chromatography and HPLC-DAD-ESI/MS analysis. To compare the antioxidative and anti-inflammatory capacity of Aronia melanocarpa berries, recognized for their high content of anthocyanins, isolation method was developed to obtain high-purity anthocyanins in the extract. Anthocyanin-rich fractions (ARFAM) enriched in anthocyanins were found to be potent strong inhibitory activity towards heme induced colonic epithelial cell proliferations are associated with an increased risk of colon cancer than acidic ethanol extract (AME). The immunomodulation properties were assessed in growth of both human B and T cells, its cytokines secretion such as IL-6 (interleukin-6) and TNF-α (tumor necrosis factor-alpha). AME enhanced interleukin-6 and reduced tumor necrosis factor-a production, whereas ARFAM only had a effect in increasing of IL-6 expression. Conclusion : These results demonstrated that there was no major relationship between the antioxidative and immunomodulation capacities of AME and ARFAM.

Background : This study was performed to investigate by antioxidant activity, total phenolic contents, total flavonoid contents, and effective component of Astragalus membranaceus treated with different artificial light Sources (fluorescent lamp, red, blue, green, white, LEP). Methods and Results : We investigated the effects of various artificial light sources on the DPPH radical activity, total phenol and flavonoid contents, tyrosinase activity and main flavonoid compounds contents (formononetin and calycosin) and other biological activities in A. membranaceus. Antioxidant activities were 53.6% as the highest level of activity under LEP light. Growth under LEP light also produced the highest total phenolic and flavonoid contents of 36.05 and 5.94 mg/ml, respectively. Extracts from plants grown under LEP light caused the highest inhibition of tyrosinase activity with inhibition of 35.37, 61.87, and 65.49%, respectively, for extract concentrations of 100 μg/ml, 500 μg/ml, and 1000 μg/ml compared with other artificial light treatments. Conclusion : Little information is available on the influence of LED and LEP light sources on antioxidant production or other biological activities in A. membranaceus. Our goal in this study was to determine the effects of LED and LEP artificial light sources on the production of new functional compounds in A. membranaceus.

Background: Cyanazine is used as a pre-emergent herbicide once during the growing season to control weeds of many upland crops worldwide. This study aimed to establish a method to determined cyanazine residue levels in major medicinal crops by using high performance liquid chromatography-UV detection/mass spectometry (HPLC-UVD/MS). Methods and Results: Cyanazine residue was extracted with acetone from the raw products of four representative medicinal plants - Scutellaria baicalensis, Paeonia lactiflora, Platycodon grandiflorum and Angelica gigas. The extract was diluted with a large volume of saline water and directly partitioned into dichloromethane to remove polar co-extractives in the aqueous phase. It was then purifined using optimized Florisil column chromatography. HPLC analysis conducted using an octadecylsilyl column allowed the successful separation of cyanazine from co-extractives of the samples, and the amount was sensitively quantified by ultraviolet absorption at 225 ㎚ with no interference. The accuracy and precision of the proposed method were validated by conducting recovery experiments on each medicinal crop sample fortified with cyanazine at two concentration levels per crop in triplicate. Conclusions: The mean recoveries ranged from 91.2% to 105.3% for the four representative medicinal crops. The coefficients of variation were less than 10%, irrespective of the sample types and fortification levels. The limit of quantification of cyanazine was 0.02 ㎎/㎏ as verified by the recovery experiment. A confirmatory method was performed by liquid chromatography/MS using selected-ion monitoring technique to clearly identify the suspected residue.

Background: This study examined the use of new bio-materials with enhanced value and functionality, which were derived from fermented wild ginseng cultures. Methods and Results: To examine the antioxidant activity associated with biological functions, radical scavenging analyses (2,2- diphenyl-1-picrylhydrazyl, DPPH and 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid, ABTS) and superoxide dismutase (SOD)-like activity analyses were conducted. Furthermore, the total phenolic and flavonoid contents of wild ginseng fermented with microorganisms (Leuconostoc mesenteroides, Bacillus circulans, Bacillus licheniformis and B. subtilis subsp. inaquosorum) were evaluated to determine the antioxidant activity increment. Regarding ginseng fermented with B. licheniformis, values of 70.6 ± 1.4%, 44.3 ± 1.7%, and 88.4 ± 1.3% were measured using DPPH, ABTS, and SOD-like antioxdiant activity analyses, respectively. The total phenolic content in ginseng fermented with B. licheniformis was 184.5 ± 0.9 ㎍• GAE/㎖, and the total flavonoid contents was 108.5 ± 1.8 ㎍• QE/㎖ in ginseng fermented with L. mesenteroides. Conclusions: Of the four types of lactic acid bacteria examined, the use of B. licheniformis to ferment ginseng resulted in greatest increase in antioxidant activity. Therefore, ginseng fermented by microorganisms might be used to produce functional bio-materials.

Lepisorus thunbergianus (Kaulf.) Ching has been used in folk medicine in Korea.
