  • The Vietnamese occurrence of Stephania subpeltata H. S. Lo (Menispermaceae) is reported here for the first time. It is morphologically allied to S. japonica but differs in having subpeltate, ovate deltoid or broadly deltoid to subdeltoid leaves, shorter petiole, fewer leaf veins, conspicuously pedicellate umbelliform cymes which are seldom compound, and purple flowers and endocarp with a reduced number of abaxial rows. A taxonomic description, distribution details, ecology, and a key to the Vietnamese species of Stephania are provided.

  • Many plants collected at Japan, China, Korea, Imdonesia and South America were applied to antitumor and / or cytotoxic screening tests against Sarcoma 180 ascites in mice and / or V-79, KB, P388 cultured cells. On the course of these screening tests, alcoholic extracts of Forsythia viridissima (Oleaceae), Eurycoma longifolia(Simaroubaceae), Rubia cordifolia and R. akane(Rubiaceae), Cissampelos pareira and Abuta concolor (Menispermaceae), Nardostachys chinensis (Valerianacese), Mansoa alliaceae (Bignoniaceae), Casearia sylvestris (Flacourtiacear), Maytenus ilicifolia (Celastraceae), Hedychium coronarium (Zingiberaceae), Croton palanostigma(Euphorbiaceae), Cocculus trilobus(Menispermaceae), Ginkgo biloba(Ginkgoaceae), Alpinia galanga and Cucculus zanthorrhiza(Zingiberaceae), Evodia rutaecarpa(Rutaceae), and Periploca sepium(Asclepiadaceae) showed significant activity and their active principles were clarified. In this paper, a few antitumor substances in above plants are introduced.

  • Tiliacora racemosa Colebr. belongs to the family Menispermaceae, the biggest storehouse of diphenylbisbenzylisoquinoline (DBBI) alkaloids. Exhaustive chemical processing of the root of T. racemosa by the application of modern separation techniques yielded a DBBI alkaloid which was identified as tiliacorine using sophisticated spectroscopic methods $(UV,\;IR,\;^1H-NMR,\;Mass)$. Tiliacorine possesses neuromuscular blocking activity. It produces a dose dependent hypotensive effect in rats and cats, and this effect is blocked by atropine.

  • Tiliacora racemosa Colebr. belonging to the family Menispermaceae, is the biggest storehouse of diphenyl bisbenzylisoquinoline (DBBI) alkaloids. Exhaustive chemical processing of the root of T. racemosa by the application of modern separation techniques yielded a DBBI alkaloid which was identified as tiliacorine using sophisticated spectroscopic methods (UV, IR, $^1H-NMR$, MS). Haematological study with tiliacorine proved that there was no abnormal haematological results in comparison with the normal values. Chronic toxicity study with tiliacorine revealed that the alkaloid is devoid of any hepatotoxic and nephrotoxic action.

  • Two new bisbenzylisoquinoline alkaloids tiliacosine (1) and tiliasine (2) were isolated from the leaves of Tiliacora racemosa Colebr.. The structures of these alkaloids were established on the basis of spectral evidence and by the correlation of their $^1H-NMR$ spectral data with those of the congeners N-methyltiliamosine (3), tiliamosine (4) and tiliacorine (5).

  • Tiliacora racemosa Colebr. belonging to the family Menispermaceae is the biggest store-house of diphenyl bisbenzylisoquinoline (DBBI) alkaloids. Exhaustive chemical processing of the root of T. racemosa by the application of modern separation techniques yielded a DBBI alkaloid which was identified as tiliacorine using sophisticated spectroscopic methods (UV, IR, $1^H-NMR$, Mass). Tiliacorine potentiated the sleeping time induced by standard hypnotics viz. chlorpromazine (CPZ), pentobarbitone (PB) and diazepam (DZ) in a dose dependent manner. Tiliacorine potentiated the analgesic action of standard analgesic agents viz., morphine and meperidine. It was also found to possess anti convulsive activity in the strychnine induced convulsion model.

  • Chromatographic separation of the MeOH extract from the stems and rhizomes of Sinomemium acutum led to the isolation of nine alkaloids and a lignan. Their structures were determined to be dauriporphine (1), bianfugecine (2), dauriporphinoline (3), menisporphine (4), (-)-syringaresinol (5), N-feruloyltyramine (6), acutumine (7), dauricumine (8), sinomenine (9), and magnoflorine (10) by spectroscopic means. These compounds were examined for their P-gp mediated MDR reversal activity in human cancer cells. Compound 1 showed the most potent P-gp MDR inhibition activity with an $ED_{50}$ value $0.03\;{\mu}g/mL$ and $0.00010\;{\mu}g/mL$ in the MESSA/DX5 and HCT15 cells, respectively.
