  • In this study, we prepared CheonJeongKiBo-Dan(7 oriental medicinal plants, 7OMP: Astragalus Membranaceus root, Panax Ginseng root, Glycyrrhiza Glabra (licorice) root, Schizandra Chinensis fruit, Polygonatum Odoratum, Rehmannia Glutinosa root, Paeonia Albiflora root) by extracting them in one reactor and studied its efficacies on skin. UV irradiation has been suggested as a major cause of photoaging in skin. In order to investigate protective effects against UV-B induced cellular damage, 7OMP was extracted with 70% ethanol and dissolved in DMSO. The protective effect was detected by MTT assay, reactive oxygen species (ROS) generation, phosphorylation of ATR and p53 in human dermal fibroblast cell system after UV-B irradiation. 7OMP reduced UV-B-induced cellular damage in HDFs cells, and inhibited ROS generation. UV-B-induced toxicity accompanying ROS production and the resultant DNA damage are responsible for activation of ATR, p53 and Bad. In this study, 7OMP hampered phosphorylations of ATR and p53 in human dermal fibroblasts. Therefore, 7OMP may be protective against UV-induced skin photoaging.

  • Estrogen like activities were evaluated using ethanol and hot water extracts of herbal medicines by using an in vitro detection system. Bokryung (Poria cocos), Sanyak (root of Dioscorea batatas) and Mokdanpi (root skin of Paeonia suffruticosa) represented statistically significant estrogen-like activities (p<0.001), while Omija (fruit of Schizandra chinensis), Taeksa (root of Alisma canaliculatum A. BR.), Jihwang (root of Rhemannia glutinosa), and Sansuyu (fruit of Cornus officinalis) did not. Estrogen-like activities of Bokryung hot water extract (500 ${\mu}g/ml$) and ethanol extract (50 ${\mu}g/ml$) were almost same as that of a C M $17{\beta}$-estradiol. Furthermore, estrogen-like activities of ethanol extracts (500 ${\mu}g/ml$) of Bokryung and Mokdanpi were stronger than that of $10^{-7}$ M $17{\beta}$-estradiol. These results suggest that Bokryung, Sanyak and Mokdanpi show estrogen-like activities. Especially, Sanyak and Mokdanpi represented promotive effect on the proliferation of MC3T3-E1 osteoblastic cells. Bokryung, Sanyak and Mokdanpi also exhibited superior inhibitory effect on the viability of RAW 264.7 cells. In conclusion, these three herbal medicines might be interpreted as candidates for the further study or development of functional foods or medicine to prevent or avoid postmenopausal symptoms of women.

  • Among 230 species of herbal drugs screened, thirty one show the anthelmintic activities in vitro against Clonorchis sinensis, the chinese liver fluke. The active substances have been isolated and their structures identified. Some of the active substances and their derivatives have been synthesized, followed by anthelmintic activity tests. The extracts from the active drugs cause damages in organs of the adult worm in the hepatic duct of rabbit. Some fresh water fish, which function as bad hosts for the fluke, excrete defense substances against the cercaria of the fluke. The defense substances have been isolated from Cyprinus carpio and Cyprinus carpio nudus, followed by structural identification. The results are summarized as follows: l) The bark of Machilus thunbergii as well as the seed of Schizandra chinensis contain meso-dihydro-guaiaretic acid as the anthelmintic component. Among derivatives synthesized, 4-phenyl-1-((3, 4-dihydroxyphenyl)-, 4-phenyl-1-(3-hydroxy-4-methoxy phenyl)-and 4-phenyl-1-(4-hydroxy-3-methoxy phenyl)-2, 3-dimethyl butanes show considerable activities. Administration of the bark extract mainly damages the bladder of the adult worm. 2) The active substance from the roasted fruit of Prunus mume is 2-hydroxymethylfurfural. This substance is produced during the roasting process. Administration of the fruitextract causes a damage of the bladder of the adult worm. 3) The active substance from the root of Scutellaria baicalensis is 5.2'-dihydroxy-6, 7, 8, 6'-tetramethoxyflavone. 4) Beside alantolactone, a very strong anthelmintic component is contained in the root of Inula helenium. Administration of the root extract causes irreversible damage on the worm, affecting mainly the reproductive organs. 5) The cercaricidal substances from the epidermis of C. carpio and C. carpio nudus are ethyl linoleate and linoleic acid, respertively. 6) The cercaricidal substances from various kinds of fresh water fish have different $R_f$ values, implying that the defense substances are species-specific. Unexpectedly, the fish with good host function, for example Pseudorasbora parva, excrete the defense substances, too. The defense substances are possibly organ-specific in individual species; the organs essenstial for the existence of the species excrete the defense substances, allowing other parts to be invaded by the cercaria. 7) The cercaricidal fraction of Carassius carassius is detected only in the fish which have been collected during the summer time from May to September, Its secretion is not dependent on water temperature. Thus, it seems to be possible that the secretion of the defense substance would be stimulated through a contact between the fish and cercaria.

  • 본 연구는 건조 오미자 추출액을 이용하여 오미자와인을 발효하였다. 건조 오미자를 YM배지에 분주하고 반복 배양하여 알코올 발효효모 OM-1 및 OM-2를 분리하였다. 분리균은 $10^{\circ}Brix$로 보당한 오미자 추출액배지에서 10% 이상의 알코올을 생성하였으며, OM-2로 발효한 오미자와인의 관능적 특성이 OM-1으로 발효한 와인보다 우수한 것으로 평가되었다. 분리균 OM-2는 0.1% urea, 0.02% mineral mixture를 첨가한 오미자 추출액배지에서 균체증식이 유의적으로 촉진되었으며 vitamin mixture는 urea가 첨가된 경우에만 약간의 증식촉진 효과를 나타내었다.

  • 본 연구는 서울지역에서 유통되는 식품원료 약용식물을 대상으로 식품공전의 다종농약다성분시험법에 의하여 100종 농약을 분석하였다. 사용부위(뿌리 82건, 과일 113건, 피층 29건, 전초 10건, 종자 18건)와 원산지(국산 201건, 수입 60건)로 구분하여 총 30종 261건 시료를 분석하였다. 원산지별 농약 검출율은 국산 20.9%, 수입 13.3%로 국산의 농약 검출율이 높았다. 전체 시료 261건 중 농약 검출율은 19.2%이며, 과일, 뿌리 시료에서만 농약이 검출되었고, 잔류허용기준을 초과한 시료는 대추와 천궁 1건씩 이였다. 과일시료의 농약 검출율은 39.8%였고, 농약검출 품목은 대추, 구기자, 복분자, 산수유, 오미자, 귤피였다. 뿌리시료의 농약 검출율은 6.1%였고, 농약 검출 품목은 천궁, 감초, 황기였다. 검출된 농약은 모두 17종으로 과일에서 15종, 뿌리에서 7종 농약이 82회 검출되었다. 검출빈도가 높은 농약은 cypermethrin, chlorpyrifos, cyhalothrin, fenvalerate, bifenthrin 순이였다. 농약이 검출된 시료 중 50%이상이 2종 이상 농약이 동시에 검출되었다. 따라서 식품원료 약용식물 중 국산 과일, 뿌리의 농약 검출율이 높고, 검출 농약의 종류가 다양해지고 있어 지속적인 모니터링과 안전관리가 요구된다.
