Abstract:
Objective: To study the chemical constituents of Pouzolzia zeylanica var. microphylla. Methods 95% ethanol was used for reflux extraction. The solvent extraction method was used to extract the alcohol extracts. The ethyl acetate extracts were separated by normal phase and reversed phase column chromatography and semi-preparative high performance liquid chromatography. The compounds were determined by spectral analysis. Results Ten compounds were isolated and identified from the ethyl acetate part of P. zeylanicaas, which were (2R,3S,4R,5S)-2,5-bis (4-hydroxy-3-methoxyphenyl)-3,4-bis (3,5-dihydroxybenzene) terahydrofyran (1), pouzolignan K (2), saropeptide (3), dehydrocuciferol (4), p-hydroxybenzoic acid (5), isovanetic acid (6), protocatechuic acid (7), syringic acid (8), protocatechuic aldehyde (9), and ethyl protocatechuate (10), respectively. Conclusion Compound 1 is a new compound named isopouzolignan K, and compounds 3—10 are isolated from this genus for the first time.
