본 연구는 4주간의 동계훈련기간 중 산수유 추출물을 섭취시켜 간 기능, 근 손상 및 혈중 피로물질에 미치는 영향을 구명하기 위하여 남중 축구선수 20명을 대상으로 동계훈련+산수유 추출물 섭취군(10 명), 동계훈련군(10명)으로 구분하여 실시하였다. 동계훈련은 1일 오전, 오후, 야간운동으로 구분하여 주 6 일, 4주간 실시되었으며, 운동강도는 70-95%HRR로 수행되었다. 산수유 추출물은 매일 아침과 저녁 식사 후 각각 80 mL(1일 160mL)를 4주간 섭취시켰으며, 측정된 자료의 그룹 내 변화는 대응표본 T검정, 그룹 간 차이는 변화율을 산출 한 뒤 독립표본 T검정을 이용하여 비교 분석하였다. 그 결과 혈중 피로물질의 젖산은 동계훈련+산수유 추출물 섭취군에서 유의하게 감소하였으며(p<.05), 동계훈련군 보다 동계훈련+산수유 추출물 섭취군이 유의하게 감소하였다(p<.05). 암모니아는 동계훈련+산수유 추출물 섭취군(p<.05), 동계훈련군(p<.001) 모두 유의하게 증가하였다. 근 손상지표의 CK는 동계훈련+산수유 추출물 섭취군이 유의하게 감소하였으며(p<.05), LDH는 동계훈련+산수유 추출물 섭취군(p<.001), 동계훈련군(p<.05) 모두 유의하게 감소하였다. 간 기능 효소 중 AST(p<.01), ALT(p<.05)는 동계훈련+산수유 추출물 섭취군이 유의하게 감소하였으며, AST는 동계훈련군 보다 동계훈련+산수유 추출물 섭취군이 유의하게 감소하였다. 동계 훈련 시 피로에 쉽게 노출 될 수 있는 선수들에게 있어 산수유 추출물 섭취는 항피로의 역할을 하는데 긍정적인 영향을 미치는 것으로 사료된다.
산수유 종자 추출물의 천연 방부제로서 가능성을 평가하기 위하여 항균활성 및 화장품 방부 효능 평가를 실시하였다. 산수유 종자는 각각 1,3-부틸렌글리콜과 에탄올을 이용하여 추출하였다. Paper disc method로 항균활성을 평가한 결과 Staphylococcus aureus, Staphylococcus epidermidis와 Propionibacterium acnes에서 항균활성이 나타났으며 산수유 종자 1,3-부틸렌글리콜 추출물(COS-A)이 여드름균에대해 26.7±4.0mm로 가장 높았다. 최소저해농도(MIC) 측정 결과 산수유 종자 에탄올 추출 물(COS-B)이 가장 낮은 농도에서 S. epidermidis균의 생장을 억제하였다. 에멀션에서의 방부효능 평가 를 위해 Challenge test를 실시한 결과 COS-A와 COS-B를 첨가한 에멀션에서 균 접종 7일 후 피부상 재균이 100% 사멸되었다. 이러한 결과는 산수유 종자 추출물이 화장품에서 합성방부제를 대체할 천연 방부제로서 가능성이 있을 것으로 사료된다.
The aim of this study was to investigate the method validation for the determination of loganin content in Cornus officinalis (CO). This medicinal plant reportedly mainly included loganin. The specificity, linearity, precision, accuracy, limit of detection (LOD), and quantification (LOQ) were measured by HPLC/DAD. Our results showed that high linearity in the coefficient of calibration correlation (R2) for loganin standard was 1. LOD and LOQ for loganin were 0.007 and 0.026 mg/mL, respectively. The recovery rate of loganin was revealed to be in the high range of 95.14-105.45%. The relative standard deviation of intra- and inter-day precision of loganin in CO was 1.8% and 2.3%, respectively. The loganin content of CO from Gurye, Uiseng, Ichoen, and China were 7.81, 3.41, 7.42, and 6.52 mg/g, respectively. In conclusion, these methods were validated for the detection of loganin in CO.
In this study three types of domatia; Tuft (T), Pocket-Tuft (PT) and Pocket (P) were observed on some species of the genus Cornus. Cornus officinalis Sieb & Zuee and C. florida Linnaeus possess T type, C. controversa Hemsl and C. walteri Wangerin possess PT type while C. alba Linnaeus possess P type. A total of 120 leaves were investigated for foliar mite’s population. T type domatia was the habitat of 329 mites (48.89%), followed by PT type where 198 mites (29.41%) were found, and the least favored was the P type domatia that accommodated 146 mites (21.70%) out of 673 mites in total. The mean number of mites per domatia was 8(±0.22), 4(±0.95) and 3(±0.70) for T, PT and P type, respectively. The alternative hypothesis that foliar mites prefer T type domatia as a habitat than PT and P type domatia was accepted based on these findings at a probability of P<0.05. Thus, it was concluded that foliar mites prefer T type domatia than the other two types. This could be due to the nature and efficiency of T type domatia in ensuring mites protection from predators and unfriendly environmental conditions. Therefore, the presence of denser tufts lowers the risks of predation and unfriendly environmental conditions and results in a higher number of mites.
Three types of leaf domatia; Pocket (P), Tufts (T) and Tufts-Pocket (TP) were observed in the five species of Cornus namely; Cornus kousa, C. controversa, C. officinalis, C. walteri and C. alba. In C. walteri no tufts were observed, the domatia was just a well developed pocket one. In C. officinalis and C. kousa, tufts domatia of brownish color were observed but C. officinalis developed denser tufts than those observed in C. kousa. Unlike in C. kousa where the domatia covered about only ½ of the axil, in the C. officinalis tufts covered almost ¾ of the axil. In both species the tufts domatia were located in the inner side of the leaf axil. In C. controversa and C. alba whitish colored tufts were observed covering Pockets and hence the Tuft‐Pocket domatia. In C. controversa the tufts were more than in C. alba but in both species the tufts were short and were located in the inner sides of the axil. Thus, based on these physiological features it was concluded that C. officinalis and C. kousa are sister species likewise C. controversa and C. alba while C. walteri belong to another lineage. The advancement of domatia (absence of tufts) in C. walteri suggests that they are the most advanced while C. officinalis and C. kousa the most primitive due to their possession of highly developed tufts and C. controversa and C. alba the intermediates.

본 연구는 국산 전통차 개발에 관한 실험으로써 산수유, 구기자 및 그 혼합물이 생체에 미치는 효능을 구명하고자 이들의 추출물을 미생물(Saccharomyces cerevisiae)과 실험동물(spraque-dawely(male)200g)에 투여하여 생리조사를 실시하였다. 미생물에 있어서는 산수유와 구기자의 첨가량이 증가할수록 균체생육이 증가했으나, 그중 산수유보다 구기자가 더 현저한 증가를 보였고, 특히 그 혼합구에서는 상승효과가 인정되었다. 흰쥐의 경우에는 산수유, 구기자 및 그 추출물이 CCl4로 야기된 간 손상에 미치는 영향을 관찰했다. GOT, GPT 활성도는 CCl4 중독에 의해서 대조군(S1)이 정상군(S0)에 비해 현저히 증가했으나 구기자군(S3)과 혼합군(S4)은 현저한 감소를 보였다(p〈0.01). 그 혈액중의 creatinine, BUN, glucose 함량은 시험구 모두 정상치에 접근했으나, 그중 구기자군(S3)이 좀 더 안정된 수치를 보였다. 따라서 CCl4의 저해에 대한 흰쥐의 간장보호 효과는 구기자, 그 혼합물, 산수유 순이고 이들 혼합물은 단일사용보다 상승효과가 인정되었다.
Yogurt is mostly consumed dairy food and considered as a nutritious food because of its probiotics such as lactic acid bacteria (LAB). LABs are known to possess antioxidant, anticarcinogenic and antimicrobial effects. Corni fructus has healthy and pharmacological effects such as the inhibition of apidogenesis and angiopoiesis. Thus, the purpose of this study was to evaluate quality characteristics and antioxidant activity of yogurt supplemented with water and ethanol extracts of corni fructus. Yogurt was manufactured with addition of 0.1%-0.2% (w/v) water or ethanol corni fructus extracts, respectively. For quality characteristics, pH, chromaticity, viscosity and syneresis were determined during refrigeration storage (1, 7, 14, and 21 day). For antioxidant activities, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging activities were examined during storage. The pH showed no significant difference between groups but showed decreasing pattern for all groups during storage period. In chromaticity, redness increased, and lightness decreased as the amount of corni furctus extracts increases. Yogurt with corni furctus ethanol extracts showed more color changes than yogurt with corni furctus water extracts. Viscosity increased in corni furctus extract added groups, compared to control. Syneresis was approximately 2-fold higher in corni fructus extract added groups, while there were no significant changes between control and extract added groups. Both DPPH and ABTS radical scavenging activities were significantly higher than control group in corni fructus extract added groups, compared to control. In conclusion, addition of corni fructus extracts in yogurt improved quality characteristics during storage and antioxidant properties.

Erectile dysfunction (ED), also known as impotence, is the inability to attain and sustain an erection firm enough to have sexual intercourse. Frequent ED may be a symptom of health problems including heart disease, obesity, alcoholism, stress, smoking, and depression, that need treatment. This study aimed to effect of complex extract (CPL) including Cornus officinalis on sexual function factor in the erectile dysfunction rat model. The erectile dysfuction rat model was induced by cimetidine (500 ㎎/㎏ in 5% ethanol, oral injection 2 weeks). Rats were oral administered with different concentration of CPL in rat erectile dysfunction model. As a results, sexual function factors (NO, cGMP) significantly improved in CPL treated groups (CPL-300, 600, 900 ㎎/㎏) compared to CON group. Serum testosterone was increased in a dose-dependent manner after CPL treatment. Furthermore, administrations of CPL restored lumen areas of the prostate in the erectile dysfunction rat model. These results indicated that CPL alleviated erectile dysfunction by increasing sexual function factor and testosterone in rat model. CPL could be used to natural treatement for erectile dysfunction. However, further study is required to identify active ingredient and its mechanism of erectile dysfunction.
말채나무는 한국의 민간요법으로 사용되던 약재이다. 자외선은 피부의 광손상을 일으키는 것으로 알려져 있다. 본 연구에서는 자외선에 의한 손상된 세포를 회복시키기 위해서 효소처리 된 말채나무잎추출물(CWE)을 사용하였다. 섬유아세포에 UVB를 조사한 후, CWE를 처리하여 세포의 회복을 조사하였다. UVB를 조사한 섬유아세포에는 caspase-3 활성, phospho-p53, γH2AX, cyclobutane pyrimidine dimers (CPDs) formation, 그리고 DNA fragmentation이 증가하게 된다. 그러나 CWE를 UVB가 조사된 섬유아세포에 12 h 처리하였을 때 caspase-3 활성, phospho-p53, γH2AX, CPDs formation, 그리고 DNA fragmentation이 감소하였다. 또한 CWE은 인체첩포시험을 통해 인체피부에 자극을 유발하지 않음을 확인하였다. 이러한 결과를 종합할 때 CWE는 자외선에 대한 광보호 효과가 있는 원료로서 가능성을 가지고 있다고 판단된다.
