An extensive anticancer drug screening from natural resources has been carried out primarily using murine tumor model for past fourty years. Recently a new screening program from NCI, so called disease-oriented screening system. has been estabished to detect anticancer drugs that show selective growth inhibition toward variety of tissue specific human solid tumors originated from leukemia, lung, colon, CNS, melanoma, ovarian, renal, prostate amd breast. To develope the anticancer drugs from oriental medicinal herbs, we investigated the cytotoxic effects against human tumor cell panels with 23 kinds of MeOH extract of medicinal herbs. Evodiae Fructus, Meliae Toosendan Fructus, Saussureae Radix and Pharbitidis Semen showed strong activities against several tumor cell lines.

Serotonin (5-hydroxytryptamine, 5-HT) has been known to have peripheral actions as well as central actions. Recently physiological roles of 5-HT as a central neurotransmitter have been studied in detail and this is a subject of the present study. Plausible central actions mediated by 5-HT receptor seem to be a control of appetite, bring about psychiatric disorders such as anxiety or dementia, and migraine headache. In this study, thirty-five medicinal plants were tested for their antagonistic activities to 5-HT mediated actions. Through the preliminary screening, methanol extracts of three medicinal plants (Saussureae Radix, Sanguisorbae Radix and Xanthii Fructus) were shown to possess relatively specific antagonistic activities to 5-HT mediated ileal contraction over acetylcholine. To luther investigate the central antagonistic activities of the selected plant in vivo, m-chlorophenylpiperazine (mCPP) which is known to be a 5-H $T_{1c}$ receptor agonist was injected to mouse to induce an anxious and/or hypolocomotion states, and also social interaction test, which was based on the method described by File (S.E. File, 1980), was performed to see whether ethylacetate fraction of Sanguisorbae Radix methanol extract possessed a specific anxiolytic activity.y.

Aristolochic acid has been known to be a carcinogenic compound and to cause Chinese herbs nephrophathy(CHN). To determine the content of aristolochic acid in various medicinal herbs marketed domestically, samples of Aristolochia fangchi, Aristolochia fructus, Aristolochia radix, Asiasari radix, Saussureae radix, and Akebia caulis were analyzed using TLC and HPLC. The optimal conditions for TLC and HPLC using $C_{18}$ column were established for the quantitative analysis of aristolochic acid. This study showed that Aristolochia fangchi and Aristolochia fructus examined in this study contain aristolochic acid of 3.9 and 2.3 mg/g sample, respectively. In contrast, aristolochic acid was not detected in the other samples.

Activation of the T lymphocytes results in a variety of early biochemical events ultimately leading to cell proliferation and lymphokine production. Stimulation of the signal transduction cascade in T cells through the T cell receptor coincides with activation of the phosphatidylinositol-phospholipase C (PI-PLC) pathway. Therefore, we have established a model system to screen immune-simulator that can increase the hydrolysis of phosphoinositides in human T cell leukemia Jurkat cells. As a result of screening from herbal medicine extract, 4 extracts (O1ibanum, Ephedrae Herba, Real Gar, Saussureae Radix) were found 14 increase the production of inositol phosphates. All the active fraction from the four kinds of extract were fluted in a different retention time on C-18 HPLC and these active fraction also showed difference in cell specificity. And all the active fractions increased DNA synthesis in T cell. Therefore, it is suggested that the active fraction among 4 extracts might contain a compound having different properties one another.

To screen the effective materials for hair loss treatment, several natural extracts were tested using in vivo and in vitro test models. Firstly, all test materials were applicated onto the back skin of C57BL／6 mouse and then hair growth pormoting effect were measured using hair growth index As a result, Polygonum muitifiorum Thunb and Terrninalia chebula Retz. showed potent hair growth promoting effect, ranking as 1.5-2.0 of hair growth index. However, there were no plant extracts, which have remarkable potential of growth promotion of human hair dermal papilla cells cultured in vitro. In the experiments of 5${\alpha}$-reductase type Ⅱ inhibition assay, Morus alba L., Chaenomelis Fructus, Saussureae Radix, Angelicae Gigantis Radix, Polygonum multifiorum Thunb, and Angelica dahurica (Fischer) Bentham et Hooker f. showed effective potential to inhibit the activity of 5${\alpha}$-reductase type Ⅱ. To investigate the possible involvement of effects of several plant extracts on the gene expression of growth factors in human hair dermal papilla cells, RT-PCR analyses were performed. As a consequences, Mentha haplocalyx Briq., Cimicifuga foetida L., Eclipta prostrata (L.) L., Pinus densiflora S. et. Z, and Polygonum muitifiorum Thunb revealed the regulatory roles on the expression of growth factors such as IGF-I, KGF, HGF and VEGF in the dermal papilla cells. Another test for inhibition of microbial such as P. acne and P. ovale were also carried out to find whether these plant extracts have anti-microbial activities. Morus alba L. and Chaenomelis Fructus showed anti-microbial effects on Propionibacterium acnes, which is believed as a pathogen of acne. Together, these results showed several plant extracts can be used for hair growth promotion.

In this study, we investigated the antioxidant and antibacterial activity of methanol extracts from 6 plants which were Chrysanthemum zawadskii Herb. var. latilobum (Maxim.) Kitamura (Gu-jeol-cho), Lavandula spica L. (Lavender), Rosmainus offcinals L. (Rosemary), Cymbopogon citrates (Lemongrass), Saussureae radix (Mok-hyang), Calendular officinalis L. (Calendular). Antioxidative effects of herbal extracts were measured by polyphenols, flavonoids contents and DPPH radical scavenging activity assay. We also evaluated the antibacterial activity against Staphylococcus aureus and Escherichia coli O157:H7. Methanol extracts from Gu-jeol-cho, lavender, rosemary and lemongrass showed high polyphenols contents as well as strong DPPH scavenging activity. In particular, rosemary extract contained highest polyphenol levels as $126.69{\pm}2.62{\mu}g/mg$ compared to other herbs. As for DPPH radical scavenging activities, $IC_{50}$ values of rosemary extracts were $6.23{\pm}0.58{\mu}g/mL$. The rosemary extracts also showed higher antibacterial effects against S. aureus and E. coli O157:H7. These results indicate that rosemary could be used as natural antioxidant and antibacterial agents.
