[Chemical constituents of Drosera peltata Smith var. lunata (Buch.-Ham.) C.B. clarke collected in Tibet].
OBJECTIVE
To investigate the chemical constituents of the whole plant of Drosera peltata var. lunata collected in Tibet.


METHODS
Compounds were separated by means of pH gradient extraction and rechromatography on silica gel, and the structures were determined by spectral analysis and physicochemical evidence.


RESULTS
Five crystalline compounds were obtained and elucidated as plumbagin(1), droserone(2), hydroxydroserone(3), beta-sitosterol(4) and stigmasterol(5) respectively.


CONCLUSIONS
Compound 3 and 5 were isolated from the plant for the first time.
