ABSTRACT
Objective:
To study the chemical constituents from fruits of Michelia yunnanensis.Methods:
The chemical constituents were isolated and purified by column chromatographies on silica gel and Sephadex LH-20. Their structures were elucidated on the basis of spectroscopic data.Results:
Twelve compounds were isolated from methanol extract of the fruits of M. yunnanensis and the structures were identified as 13-methoxy-11β, 13-dihydrocostunolide (1), lanuginolide (2), tulipinolide (3), lipiferolide (4), costunolide (5), parthenolide (6), 11β, 13-dihydroparthenolide (7), 4α, 5β-epoxy-13-methoxy-11βH-germacra-1 (10)-en-12, 6α-olide (8), cyperusol C (9), aromadendra-4β, 10α-diol (10), 9-oxonerolidol (11), and 11, 13-dehydrocompressanolide (12).Conclusion:
Compound 1 is isolated as a new natural product. 1H-NMR and 13C-NMR data of compounds 1 and 2 are reported for the first time. Except compound 6, other compounds are isolated from this plant for the first time.
