OBJECTIVE
To study the chemical constituents of Bletilla striata.
METHODS
Various column chromatographies with silica gel and Sephadex LH-20 were employed for the isolation and purification. The structures of the compounds were elucidated on the basis of spectral analyses and chemical methods.
RESULTS
Three compounds were isolated from the roots of Bletilla striata (Thunb.) Reichb. f. and identified as 5-hydroxy-4-(p-hydroxybenzyl)-3'-3-dimethoxybibenzyl (I), schizandrin (II), 4,4'-dimethoxy-(1,1'-biphenanthrene)-2,2',7,7'-tetrol (III).
CONCLUSIONS
Compound I is a new bibenzyl derivative and II was isolated from this plant for the first time.
