citrusinine-i and caffeic-acid

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.

To investigate the chemical constituents of Ipomoea batatas.. Silica gel column chromatography and Sephadex LH-20 were used to separate and purify the compounds from the EtOAc and n-BuOH soluble fraction of ethanol extracts. The chemical structures were elucidated on the basis of physic-chemical properties and spectral data.. Four compounds were isolated and identify as citrusin C (1), caffeicacid (2), 3,4-di-O-caffeoylquinic acid (3), 1,2,3,4-tetrahydro-beta-carboline-3-carboylic acid (4).. Compounds 1-4 are isolated for the first time from I. batatas.
