摘要

Seed of Litchi chinensis Sonn. is a traditional Chinese medicine, having curative effects on gastric disease, diabetes,and relieving pain.[1] Two new compounds 4-O-p-coumaroylquinic acid butyl ester (1) and 3-O-p-coumaroylquinic acid butyl ester (2), along with five known compounds: 5-O-p-coumaroylquinic acid butyl ester (3),[2] 3-O-p-coumaroylquinic acid methyl ester (4),[3] n-butyl-1-β-D-fructopyranoside (5),[4] D-1-O-methylmyo-inositol (6)[5] and 1H-imidazole-2,3-dihydro-2-oxo-4-carboxylic acid methyl ester (7)[5] were isolated and purified from the ethanol extracts of the seed of L.chinensis Sonn. Their structures, shown in Figure 1, were elucidated by ESI-MS, 1H NMR and 13C NMR, including 2DNMR spectroscopy.……
