    Author: Yan RL, Liu ZG.
    Journal: Zhong Yao Cai; 2009 Apr; 32(4):522-3. PubMed ID: 19645237.
    Abstract:
    OBJECTIVE: To study the chemical constituents of polyphenols in seed of Litchi chinensis. METHODS: The seeds of Litchi chinensis were extracted by 65% ethanol, then the compounds were separated by repeated silica gel, polyamide and preparative TLC. The structures of polyphones isolated were identified by analysis of their spectral datas and chemical properties. RESULTS: Four polyphones compounds were isolated as protocatechuic aldehyde (I), protocatechuic acid (II), daucosterol (III) and (-) -epicatichin (IV). CONCLUSIONS: Compounds I , III and IV are isolated from this plant for the first time.
