Abstract: In order to provide a theoretical basis for high-yield cultivation management and learning the best fruit harvesting period, oil constituents in Symplocos paniculata fruit were analyzed and the tissue structure was observed by microscop at different development stages. The results showed that oil was accumulated as“S”curve from the 10th day after flowing, and the highest oil content was up to 36.6%. Fatty acid in S. paniculata fruit oil was mainly composed of palmitic acid, oleic acid, stearic acid, linoleic acid and linolenic acid. The content of saturated fatty acids was increased at ifrst and then decreased, and the lowest content was 20%. But the content of unsaturated fatty acids kept rising along with fruits growing up, and the highest content was up to 79%. Oil was accumulated mainly in mesocarp, endosperm and embryo in the forms of oil cells and oil bodies, and endosperm was the major oil accumulation part.
