Studies on Polar Constituents of Mosla Chinensis ‘Jiangxiangru'

Objective:To study polar constituents of Mosla chinensis ‘jiangxiangru'.Method:Silica gel column chromatography,Sephadex LH-20 gel column chromatography and MPLC were employed for the isolation and purification.The structures were identified on the basis of spectral data and chemical methods.Result:Six polar compounds were identified as follows:methyl-3-(3′,4′-dihydroxyphenyl)lactate(1),corchoionoside C(2),prunasin (3 ),sambunigrin ( 4 ),benzyl-D-glucopyranoside ( 5 ) and ( s )-pencedanol-7-O-β-D-glucopyranoside ( 6 ).Conclusion:These compounds were isolated for the first time from Mosla chinensis ‘jiangxiangru'and have not been previously described in genus Mosla.
