Chemical constituents of Glechoma longituba.

AIM: To study the chemical constituents of Glechoma longituba (Nakai) Kupr. METHODS: Manifold chromatography methods were used to separated the chemical constituents, and the chemical structures were determined by spectral analyses. RESULTS: Nine compounds were isolated from Glechoma longituba and identified, as: glecholone (1), 6R,9R-3-oxo-alpha-ionol (2), S(+)-dehydrovomifoliol (3), vomifoliol (4), corosolic acid (5), quercetin (6), stigmastenol (7), myristic acid (8) and triacontanol (9). CONCLUSION: Compound 1 is a new compound. Compounds 2 - 9 were isolated from this plant for the first time.

[Study on steroidal compounds from Dioscorea zingiberensis].

OBJECTIVE: To study the chemical constituents of Dioscorea zingiberensis. METHOD: Manifold chromatography methods were used to separate the chemical constituents, and the chemical stuctures were determined by spectral analyses. RESULT: 6 compounds were isolated from Dioscorea zingiberensis and identified as deltonin, protodeltonin, zingiberensis newsaponin, dioscin, 3-O-[beta-D-glucopyranosyl(1 --> 4)]-beta-D-glucopyranosyl-diosgenin, diosgenin. CONCLUSION: Deltonin and protodeltonin were isolated from this plant for the first time.
