The current investigation was carried out to find out the anticancer activity of the methanol extract from Buplerum falcatum against cancered ICR mouse and cancer cell lines such as J774A.1 and L1210 cells. Extract of Buplerum falcatum displayed the considerable augmentation(134%) of the survival of ICR mouse bearing Sarcoma 180 cancer. In addition, the cytotoxic effects of methanol extract of Buplerum falcatum against J774A.1 cells and L1210 cells were found to show $IC_{50}$ values of $57.3\;{\mu}g/ml$ and $54.6\;{\mu}g/ml$, respectively. In contrast to such cytotoxicity against cancer cells, the extract exerted only meagre toxicity against normal lymphocytes. The increased generation of $O_2^-$ and the considerably increased activities of super-oxide dismutase(SOD) and glutathione peroxidase(GPx) of both J774A.1 cells and L1210 cells in the presence of Buplerum falcatum extract implied that the observed cytotoxicities may have resulted from the detrimental effect of reactive oxygen species(ROS) evoked by Buplerum falcatum extract on the cancer cells.

The electron donating ability, elastase inhibitory, procollagen synthesis and Matrix metalloprotease-1 (MMP-1) activities were measured in order to verify the anti-wrinkle properties of extracts from Buplerum falcatum as a functional ingredient for cosmetic products. Electron donating ability and elastase inhibition activities were 80 and 52% at a dose of $1,000{\mu}g/mL$ of B. falcatum 70% ethanol extract. Pro-collagen synthesis was increased with the increase concentration of B. falcatum extract on CCD-986sk in addition to decrease the amount of protein of MMP-1. The results suggested that B. falcatum extract can be used to reduced electron donating ability, elastase, pro-collagen synthesis and MMP-1 activity and is a potential candidate for cosmedical materials.

During culture the effect of polyamine on hairy root of Buplerum falcatum by infection of Agrobacterium rhizogenes was studied. The fresh and dry weight of hairy root which cultured for 3months in MS medium increased about 7-fold when spermine at 10${\mu}$M, 100${\mu}$M was treated. After suspension culture of B. falcatum in MS medium containing putrescine(10${\mu}$M, 100${\mu}$M) or spermine(10${\mu}$M), the contents of endogenous polyamine (putresclne, spermidine, spermine) was higher than that of control. The ${\beta}$-glucan synthetase II activity by polyamine treatment was increased： especially spermidine (100${\mu}$M) and spermine(100${\mu}$M) stimulated it by about 180% and 220% respectively. These results suggest a possible role of polyamine as growth regulator in B. falcatum hairy root cultures.

Umbelliferae medicinal crops have low germination under natural condition. Special objective of this study is to investigate morphological characteristics of seeds and effects of environmental factors such as light and temperature on their germination and seedling growth in Umbelliferae plants, using them as oriental medicine materials. Fruits of Umbelliferae are bi-partite type and form 2 seeds. Their oil canals and funiculus or carpaphore has apparently specific shape. Seed shape of Buplerum falcatum, Ligusticum acutilobum and Foeniculum vulgare are oblong, Ledeboutiella seseloides, Angelica dahurica, Angelica gigas elliptic, and Ostericum koreanum ovate. Color of seed coats varied from yellow to dark brown. Seed size was 3.2 to 6.9 mm in length, 1.7 to 4.9 mm in width. One thousand-seed weight of Buplerum falcatum was lowest(at 1,660 mg) and Ledebouriella seseloides and Angelica gigas were relatively highest(at 3,970 mg) having larger size than any others. Optimum temperatures for seed germination and seedling growth ranged from 20 to $25^{\circ}C$ and especially temperature at $25^{\circ}C$ improved seed germinations of Ledebouriella seseloides, Angelica dahurica and Ligusticum acutilobum regardless of light condition.

Acetaminophen(이하 AAP)은 간의 mixed function oxidase system에 의해 toxic metabolite로 대사되어 간괴사를 일으킨다. 최근에는 지금까지 임상적으로 사용되어온 한약이나 생약의 cytochrome P450의 활성과 간의 glutathion 합성에 미치는 영향에 대한 연구가 활발하게 진행되고 있다. 본 연구에서는 AAP의 간독성을 억제하는 물질을 규명하고자 민간이나 한방에서 보간 또는 해독제로 많이 사용되고 있는 생약을 screening하였다. 그 결과 간의 약물대사 효소계에 엉힝을 미치는 것으로 보고된 강활(Angelica koreana)과 민간이나 한방에서 간질환치료의 목적이나 해독제로 쓰여온 시호(Buplerum falcatum), 토복령(Smilax china) 및 금은화(Lonicera japonica)가 AAP로 유발된 간독성에 미치는 효과를 살펴보았다. 방법: 예비실험을 통해 강활, 시호, 토복령 및 금은화의 MeOH ext.가 AAP로 유도된 간독성에 방어효과가 있음을 확인하고 이를 hexane, ether, ethyl acetate 및 butanol로 계통분획하여 랫트에 전처치한 후 고농도의 AAP를 투여하여 간 손상을 일으키고 혈청중의 효소활성과 지질ㆍcholesterolㆍbilirubin함량 등을 측정하였다.
