Isolation and identification of Withaphysalins from Physalis minima

To investigate the chemical constituents of Physalis minima L. , compounds were isolated by chromatographic methods from Physalis minima L. . Their structures were determined on the basis of spectral analysis. Five compounds were isolated and identified as Withaphysalin P(I), 14, 18-di-O-acetylwithaphysalin C(II), Withaphysalin Q(III), Withaphysalin 1 (IV)and Withaphysalin 2 (V). Compounds IV and V are new compounds, orderly named as Withaphysalin T and Withaphysalin U.
