[Studies on chemical constituents of Pholidota yunnanensis].

ABSTRACT

OBJECTIVE: To investigate the chemical constituents from Pholidota yunnanensis. METHOD: Various chromatographic techniques were employed for isolation and purification of the constituents. The structures were elucidated by chemical and spectral analyses. RESULT: Seven compounds were obtained and they were identified by spectroscopic analysis as n-nonacosane, cyclopholidone, n-dotriacontanoic acid, n-octacostyl ferulate, cyclopholidonol, cycloneolitsol and beta-sitosterol, respectively. CONCLUSION: n-octacostyl ferulate and cycloneolitsol were isolated from genus Pholidota for the first time.
