Abstract

Abstract

Objective Study the chemical compounds from the plants of P. yunnanensis and find its bioactive constituents. Methods The compounds were extracted by ethyl acetate and isolated by column chromatography on silica gel and Sephadex LH-20. ¹H NMR, ¹³CNMR and EI-MS were used to elucidate their structure. Results Five compounds including gigantol （1）, batatasin III （2）, 2-methoxy-4,7-dihydroxy-9,10-dihydrophenanthrene （3）, 2,7-dihydroxy-4-methoxy-9,10-dihydro-phenanthrene （4）, 2,7-dihydroxy-4-methoxyphenanthrene （5） were obtained. Conclusion Compound 5 was isolated from the plant for the first time.
- Pleione yunnanensis,
- Phenanthranes,
- Bibenzyls
