Three compounds were isolated from the roots of Astragalus membranaceus (Leguminosae). On the basis of spectroscopic evidences, the structures were characterized as $3-0-{\beta}-D-xylopyranosyl-(2',3'-O-diacetyl)-6-0-{\beta}-D-glucopyranosyl-3{\beta},6{\alpha},16{\beta},25-tetrahydroxy-20(R)$,24(S)-epoxy-cycloartane(Astragaloside I), $3-0-{\beta}-D-xylopyranosyl-(2'-O-acetyl)-6-0-{\beta}-D-glucopyranosyl-3{\beta},6{\alpha},16{\beta},25-tetrahydroxy-20(R)$,24(S)-epoxy-cycloartane(Astragaloside II), $3-0-{\beta}-D-xylopyranosyl-(2',4'-O-diacetyl)-6-0-{\beta}-D-glucopyranosyl-3{\beta},6{\alpha},16{\beta},25-tetrahydroxy-20(R)$,24(S)-epoxycycloartane(Isoastragaloside I). Full data of NMR including HMBC and 1D-TOCSY experiment of these compounds were reported for the first time.

The roots of Pseudarthria viscida (L.) Wight and Arnott. (Leguminosae) are used against various disorders in Indian systems of medicine, namely as anthelmintic, anti-inflammatory, cardiotonic, aphrodisiac, rejuvenating, tonic and as a remedy for cough, asthma, tuberculosis, diarrhoea and alternate fever. The present communication deals with the detailed pharmacognostical evaluation of the root sample using light and confocal microscopy, WHO recommended physico-chemical determinations and authentic phytochemical procedures. he physico-chemical, morphological and histological parameters presented in this paper may be proposed as parameters to establish the authenticity of P. viscida root and may possibly help to differentiate the drug from its other species.

The antioxidant activity of Desmodium oldhami (Leguminosae) was determined by measuring the radical scavenging effect on DPPH (1,1-diphenyl-2-picrylhydrazyl). The methanolic extract of D. oldhami showed the strong antioxidant activity. Five compounds, kaempferol-3-O-rhamnopyranoside (afzeline) (1), quercetin-3-O-[$\alpha$-L-rhamnopyranosyl($1{\rightarrow}6$)-$\beta$-Dglucopyranoside] (rutin) (2), kaempferol-3-O-glucopyranoside (astragalin) (3), genistein-7-O-$\beta$-D-glucopyranoside (genistin) (4), kaempferol-3-O-rutinoside (5) were isolated from the active ethyl acetate soluble fraction of D. oldhami through repeated silica gel and Sephadex LH-20 column chromatography. Among them, compound 2 showed the most significant antioxidative effect on DPPH free radical scavenging test. Compounds 1-5 are reported for the first time from this plant.

The n-butanol soluble fraction of the extract obtained from the whole plants of Ononis serrata afforded the pterocarpan derivative medicarpin-3-O-glucoside and the isoflavone glucoside rothindin. Structures were elucidated by chemical methods, detailed spectral analyses as well as comparison with the literature data.

Six flavonoids were isolated from the heartwood of Maackia fauriei. On the basis of spectroscopic evidences, the structure of these compounds were established as 4'-7-dihydroxyflavone, genistein, retusin, afromosin, dehydroferreirin and 3'-methoxydaildzein.

From the 70% EtOH extract of the roots of Astragalus membranaceus (Leguminosae), fifteen saponins were isolated and identified as astragaloside I (1), isoastragaloside II (2), astragaloside II (3), agroastragaloside I (4), cyclogaleginoside B (5), cycloaraloside A (6), brachyoside B (7), agroastragaloside II (8), astragaloside III (9), astragaloside IV (10), astramembranoside A (11), astramembranoside B (12), cylocanthoside E (13), cyclounifolioside B (14) and azukisaponin V methyl ester (15) by spectroscopic methods. Ten compounds 1 - 3, 5 - 7, 9 - 11 and 14 have cycloastragenol as an aglycon, and four compounds 4, 8 , 12, and 13 have cyclocanthogenin as an aglycon. The hairy roots of A. membranaceus were shown to produce previously unreported cycloartane-type saponins such as agroastragalosides I (4) and II (8) and cycloastragenol $3-O-{\beta}-D-xyloside$ (5), together with the known saponins. This is the first report of these saponins (4, 5, and 8) from the intact plant. Although the occurrence of the oleanane-type triterpene saponin, azukisaponin V methyl ester (15), in Astragalus plants has been demonstrated by others, this is the first report of the azukisaponin V methyl ester (15) from the Astragalus plants.

From the stems of Echinosophora koreensis Nakai (Leguminosae) acetyloleanolic acid, oleanolic acid, $\Delta^5$-sterols and scopoletin were isolated and characterized by spectral data. $\Delta^5$-Sterols were identfied as campestrol, stigmasterol and $\beta$-sitosterol in a ratio of 12%, 20% and 68% by GC/MS analysis.
