Mutagenic acivity of essential oils was tested using Salmonella typhimurium TA100 in the presence or absence of 59 fraction prepared from the mouse liver. Growth inhibitory effect of the oils on the bacteria was measured to warrant the mutagenic effect. Most oils were (round to be very strongly toxic against the bacteria at a high dose $(2,000{\mu}g/plate)$. At lower doses than this concentration, the Curcuma longa oil was found to be the most mutagenic with S9 fraction whereas it was not mutagenic without the fraction suggesting that this oil could undergo activation for the mutagenicity by cytochrome P45O. However, the mutagenicity of the Eugenia caryohpylata oil was disappeared under S9 fraction. Other oils obtained from Cinnamomum cassia, Chrysanthemum sibiricum, Paeonia moutan the flower of Artemisia princeps var. Orientalis, Allium sativum, were not mutagenic. This result suggested that antimutagenicity assay on the essential oil is necessary for the biological available substances.

Type I (collagen) and procollagen are reduced in aged human skin. This reduction could result from increased degration by metalloproteinases and from reduced procollagen synthesis and skin collagenase is required for initiation of the degration of type I collagen. In the present study, we study on assay the collagen and collagenase in natural plants using the fibroblast human skin cell. We select the 15 kind of plants used to herbal and 4 kind of fraction(by methylene chloride, ethyl acetate, n-butanol, water). Among these extract, the ethyl acetate fraction from benincasa hispida/prunus persica, trichosanthes kiriowii, trogopterus xanthipes and methylene chloride fractions from benincasa hispida/prunus persica, torilis japonica and n-butanol fraction from cnidium officinale, chrysanthemum sibiricum were selected for further experiments as they exhibited distinctive amount of collagen compared to other natural extracts. These extracts were again subjected to collagenase assay test. Benincasa hispida/prunus persica extract was shown to have exellent collagen synthesis activity from result of the collagen assay test and the other extract was shown to have over 130% of collagen synthesis activity. But, in the study of collagenase assay test just only trogopterus xanthipes extract was shown to have collagenase inhibition.

장수상황버섯(Phellinus baumii) 균사체를 이용한 한약재의 고체발효를 통한 기능성 강화 한약재 생산을 목적으로, 항산화 활성 또는 혈류 개선활성이 우수하다고 알려진 36종의 한약재를 멸균 후, 장수상황버섯 균사체를 접종하여 고체발효 가능성을 검토하였다. $2^{\circ}C$, 상대습도 90% 배양기에서 20일간 발효시킨 결과, 감국, 대추, 백부자, 신이 및 황정을 제외한 31종에서 양호한 발효가 진행되었으며, 발효 가능여부는 한약재 식물체의 사용부위의 구조적 견고성, 영양조건 및 항진균 활성 등과 연관되리라 판단된다. 한약재의 고체발효 이후, 발효전과 비교하였을 때 평균 수분함량은 $30.84{\pm}15.67%$에서 $67.21{\pm}11.43%$로 2.2배 증대되었으며, 평균 메탄올 추출효율과 평균 pH는 $13.91{\pm}12.22%$ 및 $5.06{\pm}0.87$에서 각각 $11.16{\pm}7.06%$ 및 $4.83{\pm}0.73$ 다소 감소하는 경향을 나타내었다. 각각의 메탄올 추출물을 이용한 항혈전 활성 및 항산화 활성을 측정한 결과, 골쇄보, 천련자, 도엽, 와송의 경우에는 트롬빈 저해 활성이 각각 발효전에 비하여 31.38, 23.63, 22.57, 13.85% 증가되었으며, 원지, 현삼, 백지, 향부자, 골쇄보 및 육종용에서는 DPPH 소거능이 발효전에 비해 각각 58.9, 49.8, 48.1, 32.8, 24.1, 20.7% 증가되어 장수상황버섯 균사체 발효 한약재의 긍정적 생리활성 증가를 확인하였다. 본 연구결과는 상황버섯 균사체를 이용한 한약재의 고체발효를 통해, 특정 기능성의 강화 원재료를 생산할 수 있으며, 골쇄보의 경우와 같이 항혈전 활성 및 항산화 활성이 동시에 증대된 한약재 생산이 가능함을 제시하고 있다.
