ABSTRACT
To study the chemical constituents of the fruits of Psoralea corylifolia L., the constituents were isolated and purified by chromatography. Two new compounds were isolated from the ethyl acetate-soluble fraction of the ethanol extract. On the basis of chemical and spectroscopic data 1D and 2D NMR, they were identified as 2-(3, 4-dihydroxyphenyl)-8, 8-dimethyl-8H-pyrano[2, 3-h]chromen-4-one (1) and 5-(2-hydroxyl-1-methyl)-ethyl-4, 5-dihydrofurano[2, 3-h](4'-hydroxyl-3', 5'-dimethoxy)-isoflavone (2), and named as coryfolia D and bavarigenin separately.

Survey on research and development of Fructus Gardeniae in the recent 10 years. Gardenia yellow has been used for food colorent, medicine, feedingstuff and cosmetic. Garnedia blue has been used for developing another pigment with red and yellow. Fructus Gardeniae has been used in digestive system for cholecyst constracting and gall-stone eliminating, for declining peroxide on SAP mouse and increasing immune ability, for protecting liver against cancel, anti-acetylcholinic restraining on stomach enginery, in cardiovascular system it has been used for centrally anti-hypertension, preventing atheroma and thrombus, also Fructus Gardeniae has been used for anti-inflammation, treating parenchyma injure etc. Geniposide used for increasing production in agriculture has wider perspect.

OBJECTIVE: To study the adsorption and desorption behavior of macroporous adsorhption resin AB-8 for polysaccharides in exocarp of Ginkgo biloba L. and its effect factors. METHODS: The optimum purification conditions were investigated by singal factor experiments. RESULTS: The optimum conditions were as follows: the follow rate was 1.0 ml/min, solution concentration was 10 mg/ml and the pH was 7.4-7.6. CONCLUSION: AB-8 have an upper adsorption capacity for polysaccharides in exocarp of Ginkgo biloba L. and the elution is easy. The purification of its production is 81.3%.
