采用溶剂提取法从小叶石楠果实中提取低极性化学成分，并利用气相色谱-质谱仪对果实中的低极性化学成分进行分离和鉴定，同时用面积归一法测定各成分的相对百分含量.结果表明：已确认了25种成分，占果实中低极性化学成分的96．04％，其主要成分为亚麻酸甲酯(13．11％)、邻苯二甲酸二辛醇酯(10．13％)、角鲨烯(9．19％)、维生素E(8．67％)、十九烷(8．03％).所鉴定的化合物多为该种植物中首次发现，为小叶石楠的进一步开发利用提供了科学依据.
採用溶劑提取法從小葉石楠果實中提取低極性化學成分，併利用氣相色譜-質譜儀對果實中的低極性化學成分進行分離和鑒定，同時用麵積歸一法測定各成分的相對百分含量.結果錶明：已確認瞭25種成分，佔果實中低極性化學成分的96．04％，其主要成分為亞痳痠甲酯(13．11％)、鄰苯二甲痠二辛醇酯(10．13％)、角鯊烯(9．19％)、維生素E(8．67％)、十九烷(8．03％).所鑒定的化閤物多為該種植物中首次髮現，為小葉石楠的進一步開髮利用提供瞭科學依據.

The low-and-middle polarity chemical constituents were extracted from the fruit of Photinia parvifolia by solvent extract and were isolated and identified by GC-MS method.The relative contents of the chemical constituents were determined by area normalization method.25 compounds were detected and identified which accounted for 96.04% of total low-polarity chemical constituents.And the main low-polarity chemical constituents were (Z,Z,Z)-9,12,15-Octadecatrienoic acid methyl ester (13.11%),Di-n-octyl phthalate (10.13%),All-trans-Squalene(9.19%),Vitamin E(8.67%)and Nonadecane(8.03%).Most compounds were found for the first time in this plant.It would provide scientific support for exploitation and utilization of P .parvifolia .
