ABSTRACT
Objective:
To study triterpenoids of Paliurus ramosissimus.Methods:
Six triterpenoids were obtained by modern chromatography technologies, such as repeated chromatography on silica gel, ODS, Sephadex LH-20, and preparative HPLC. Their structures were elucidated on the basis of combination of IR, mass spectrometry, and NMR spectroscopy.Results:
Six triterpenoids were isolated from the ethyl acetate soluble parts obtained from 95% aq. ethanol extract of the aerial parts of P. ramosissimus. They were identified as 22β,24-dihydroxy-A(1)-nor-2,20(29)-lupindien-27,28-dicarboxylic acid (1), zizyberenalic acid (2), 3-O-protocatechuoylceanothic acid (3), ceanothetric acid (4), 2-O-caffeoylalphitolic acid (5), and 3-O-caffeoylalphitolic acid (6).Conclusion:
Compound 1 paliurus ramosissimus acid A is a new compound. Compounds 2-6 are isolated from P. ramosissimus for the first time. And the complete NMR data of compound 3 has been presented in this paper for the first time.
