Study On Chemical Constitutes And Bioactivities Of Actinidia Polygama

Based on the theories and principles of photochemistry and modern chemical isolation and purification methods,　the chemical constituents in the seeds of A.　polygama Maxim have been studied with the combination of conventional and new methods, then we give a review on the research advances in this thesis. The systematically preliminary tests have been done by the methods of the tube-test. It was found that the seeds of A.polygama contains flavonoids and its glycosides, steroids, terpenoids, organic acid ,volatile oil ,fats and polycarbohydrates; maybe contains saponin, cardiac glycosid, AA, protein; no enthraquinones and its glycosides.The rate of fats in the petroleum extract is 56%,so we give a analysis for it by means of gas chromatography.The main constituents are Gamma linolenic,linoleic acid ,oleic and palmitic and their content is 69.28 %,12.54 %,12.29 % and 5.97 % respectively. Six compounds were isolated from petroleum ether extract and the ethyl acetate extract of seeds by means of solvent extraction, column chromatography on silica gel, purification. Their structures of CH-1, CH-3 and CH-7 were elucidated as ?-sitosterol, benzoic acid and 5-(hydroxymethyl)-2-Funancarboxaldehyde on basis of their spectral data (MS, ¹H-NMR, ¹³C-NMR) and the other compounds have not been identified. The fungicidal activities had been first studied on petroleum ether extract, ethyl acetate extract, n-butanol extract and water residues. It showed certain fungistasis aganist Glomerella cingulata and Alternaria　longipes when the concentration of the four samples was 3300 μg/mL.The insecticidal activities on Mythimna separata Walker and other fungicidal activities against Gibbere　zeae,　Glomerella　cingulata,　Fusarium　solani, Exserohilum　turcicum, Alternaria　longipes　and　Bipolaris　sorokiniana. had also been studied.
