Objective:
To study on the chemical constituents of Zephyranthes candida.
Methods:
Compounds were isolated and repeatedly purified by chromatographic techniques on silica gel column. Their structures were elucidated by chemical and spectral methods.
Results:
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).
Conclusion:
I-XIII are all isolated from this plant for the first time.
