Abstract

To investigate the chemical constituents from the tubers of Ipomoea batata.The chemical constituents were isolated and purified by solvent extraction together with various chromatographic techniques. The structures were elucidated on the basis of physiochemical property and spectral data.6 compounds were identified from the CHCl3 extract as Batatinoside I (1), citrusin C(2), octadecyl caffeate (3), beta-amyrin acetate (4), caffeic acid (5), scopoletin (6).Compound 1 is isolated from Ipomoea batata for the first time.
