CHEMICAL STUDIES ON THE CONSTITUENTS OF PLAGIOCHASM INTERMEDIUM L.

AIM　To study the chemical constituents of Plagiochasm intermedium L. METHODS　The plants were extracted with 95% EtOH and then separated by repeated silica gel and Sephadex LH-20 chromatographies. The structures of compounds isolated were identified by measurement of 1DNMR, 2DNMR spectrometry and X-ray crystallographic analysis. RESULTS　Six compounds were isolated. They were elucidated as pakyonol (I), 24-ethylcholesta-5,22-dien-3β-ol palmitic acid ester (II), 22-hopanol (III), β-sitosterol (IV), daucosterol (V), and mannitol (VI). CONCLUSION　Compound II is a new compound.
