To study on the chemical constituents of Zephyranthes candida.
Compounds were isolated and repeatedly purified by chromatographic techniques on silica gel column. Their structures were elucidated by chemical and spectral methods.
Eight compounds were isolated from the whole plant of Zephyranthes candida, and identified as (2S)-3',7-dihydroxy-4'-methoxyflavan (I), beta-sitosterol (II), stigmasta-5,22-dien-3beta-ol (III), stigmasterol (IV), beta-daucosterin (V), Butylisobutyl phthalat (VI), Heptacosane (VII) and Ambrettolide (VIII).
I-XIII are all isolated from this plant for the first time.
