ABSTRACT
Objective: To study the chemical constituents from the aerial parts of Chloranthus angustifolius. Methods: The chemical constituents were isolated by various chromatography techniques and their structures were elucidated on the basis of physiochemical properties and spectrascopic analysis. Results: Eight compounds were isolated and identified as 1-acetoxy-2,3,4,5- tetrahydroxy-5-p-metoxyphenylpentane (1), (E)-5-(4-methoxyphenyl) pent-4-ene-1,2,3-trihydroxyamyl (2), isofraxidin (3), (-)-dihydrodehydrodiconiferyl alcohol (4), (±)-erythro-guaiacyl-glycerol-β-O-4'-dihydroconiferyl ether (5), (-)-rosiridol (6), (4S)-p-menth-1-ene-4,7-diol (7), and loliolide (8), respectively. Conclusion: Compounds 1 and 2, named chloranthus pentitol and chloranthus enol, are two new p-methoxyphenyl pentitol derivatives, while compounds 3-8 are obtained from C. angustifolius for the first time.
