From the water fraction of the MeOH extract, three compounds, 1,3,4,5-terrahydroxycyclo-hexanecarboxylic acid 3-(3,4-dihydroxycinnamate) (chlorogenic acid), $quercetin 3-O-{\beta}-D-galactopyranoside(hyperoside)$, and 1 (R)-hydroxy-3,4-seco-lup-4(23), 20(30)-dien-3,$11{\alpha}-olactone-{\alpha}-L-rhamnopyrnaosy(1{\rightarrow}4)-{\beta}-D-glucopyanosy(1{\rightarrow}6)-{\beta}-L-glucopyrnaosyl$ ester (chiisanoside) were isolated and their strutures determinated by $^1H-NMR,{\;}^{13}C-NMR$, IR, and FAB-Mass. Chlorogenic acid and Chiisanoside had been quantitated by HPLC from eight Acanthopanax species per 10 g A. koreanum 19.82, 4.17 mg, A. nambunensis 65.00, 1.86mg, A. chiisanense 27.19, 8.17mg, A. sessiliflorum 7.49, 5.88 mg.

Chiisanogenin (1), hyperin (2) and chiisanoside (3) were isolated from the leaves of Acanthopanax senticosus, and were tested for their inhibitory activities against 6 strains of bacteria. Among them, chiisanogenin (1) revealed broad but moderate antibacterial activities against G(+) and G(-) bacteria, the minimum inhibitory concentration (MIC) being in the range of 50-100 $\mu\textrm{g}$/ml.

Acanthopanax divaricatus Seem. is a medicinal plant growing widely through out Korea, Japan and China. The plant material of Acanthopanax spp. is used as analgesic , tonic, sedative drug as well as for the treatment of hypertension, rheumatism and diabetes. From the stem barks and root barks of A. divaricatus, diterpenoid compound was isolated and identified as pamaric acid ($C_{20}H_{30}O_2,\;mp\;164^{\circ}C$), lignan compounds were isolated and identified as d-sesamin ($C_{20}H_{18}O_6,\;mp\;123{\sim}124^{\circ}C$), eletheroside E ($C_{34}H_{46}O_{18},\;mp\;257{\sim}259^{\circ}C$), three sterol compounds were identified as ${\beta}$-sitosterol, campesterol, stigmasterol, and six fatty acid compounds were identified as stearic acid, palmitic acid, oleic acid, linolenic acid, arachidonic acid and behenic acid. And also leaves of A. divaricatus, chiisanoside were identified, one of secotriterpenoidal compound(white amorphorous powder crystal, mp $228^{\circ}C$). Anticancer activity and nephrotoxicity were tested by MTT assay. Anticancer effect of chiisanoside was much lower than that of cisplatin.

Four 3,4-seco-lupane trierpenoids were isolated from the MeOH extract of the leaves of Acanthopanax divaricatus forma flavi-flos Yook by using various column chromatography. The chemical structures of isolates were identified as chiisanogenin, chiisanoside, isochiisanoside and 11-deoxyisochiisanoside on the basis of physico-chemical and spectroscopic date($^1H-NMR,\;^{13}C-NMR$M$, 2D-NMR and FAB-MS). These compounds were isolated for the first time from A. divaricatus forma flavi-flos.

Traditional Chinese Medicines (TCM) have attracted great interest in recent researchers as alternative medicines for incurable diseases. This review focuses on qualitative and quantitative analytical approaches for bioactive metabolites of components flavonoids and saponins of traditional Chinese medicines by TLC system, although various methods have been introduced. Emphasis will be put on the processes of metabolite extraction from intestinal bacterial cultures or urines, separation (mobile phase) and detection. The identified metabolites by selection of extraction solvent and detection methods are also discussed. In addition, metabolite determinations of flavonoids (baicalin, apiin, rutin, quercetin, quercitrin, kaempferol, diosmin, hesperidin, poncirin, naringin, puerarin, daidzin, daidzein, tectoridin) and saponins (ginsenosides, kalopanaxsaponins, glycyrrhizin, chiisanoside, saikosaponins, soyasaponins) in culture fluid, in urine and in some herbal formula extracts are summarized. These bioactive metabolites of these components by intestinal microflora should be connected to pharmacological actions.

From methanol extract of Acanthopnanax senticosus, six platelet anti-aggregating compounds, chiisanogenin (1), chiisanoside (2), ursolic acid (3), oleanolic acid (4), b-sitosterol (5) and daucosterol (6) were isolated. All of the isolated compounds showed dose-dependent inhibitory activities to rat platelet aggregation induced by all the agonist employed. Compound 1 showed about 50 folds higher potency than acetylsalicylic acid (ASA) on U46619 induced platelet aggregation (IC$\sub$50/ : 6.21 ${\mu}$M) and 10 ∼ 20 folds higher effect than ASA on epinephrine and arachidonic acid (AA) induced aggregation (IC$\sub$50/ ; 2.50 and 4.81 ${\mu}$M, respectively).
