[Studies on chemical constituents from roots of Craibiodendron henryi].[Pubmed: 17583200]
To study the chemical constituents from the roots of Craibiodendron henryi.
Iridoid glycosides and grayanane diterpenoids from the roots of Craibiodendron henryi.[Pubmed: 16309316]
Four new iridoid glycosides, 10-O-trans-p-coumaroylscandoside (1), 10-O-cis-p-coumaroylscandoside (2), 10-O-trans-p-coumaroyldesacetyl asperulosidic acid (3), and 10-O-cis-p-coumaroyldesacetyl asperulosidic acid (4), and two new grayanane diterpenoids, 14beta-O-(2S,3S-nilyl)-2alpha,3beta,5beta,6beta,16alpha-pentahydroxygrayanane (5) and 14beta-O-(2S,3S-nilyl)-2alpha,3beta,5beta,6beta,16alpha-pentahydroxygrayan-10(20)-ene (6), have been isolated from Craibiodendron henryi. The structures of these compounds were determined by chemical and spectroscopic methods including 1H-1H COSY, HMQC, HMBC, and NOESY experiments. Antioxidant activities and vasodilator effects of these compounds were assessed.
[Chemical composition of Craibiodendron henryi W. W. Smith].[Pubmed: 9642392]
Two components were isolated from the dried leaves of Craibiodendron henryi and identified as rhodojaponin II and III by means of IR, MS, 1HNMR and 13CNMR spectra. These two compounds are obtained from the herb for the first time.
