[Studies on chemical constituents of Balanophora spicata].
OBJECTIVE
To investigate the chemical constituents of Balanophora spicata.


METHODS
Various chromatographic and spectral techniques were used to isolate the constituents and elucidate their structures.


RESULTS
Eight compounds were isolated from whole plant of B. spicata and elucidated as balanophorin A (1), balanophorin B (2), beta-amyrin acetate (3), monogynol A (4), lupeone (5), caffeic acid ethyl ester (6), catechin (7), 1-O-(E)-caffeoyl-3-O-galloyl-beta-D-glucopyranose (8), respectively.


CONCLUSIONS
Compounds of 1-8 were obtained from B. spicata for the first time and the compound 4 was isolated from this genus for the first time.
