In order to guide the harvest of Camellia osmantha better,the contents of oil and components of C. osmantha were collected every other week from September 7 to November 30. Results showed that the fresh seed rate of C. osmantha changed little in the whole determination period,but with the increase of fruit maturi-ty,the dry seed rate,the yield of dry seed,the oil content of the kernel and the oil content of the converted fresh fruit all showed a upward trend and remained relatively stable until November. In terms of fatty acid com-position,the oleic acid of unsaturated fatty acids and stearic acid of saturated fatty acids also increased with the increase of fruit maturity,while the linoleic acid of unsaturated fatty and palmitic acid of saturated fatty ac-ids decreased with the increase of fruit maturity. On November 9,the dry seed rate,the oil content of the ker-nel and oil content of fresh fruit reached 33.06%,49.35%and 9.25%,respectively,which were the highest in all samples, and the content of unsaturated fatty acid in the fatty acid composition was also the highest. Therefore,the most suitable fruit picking time for C. osmantha in Nanning was in the middle of November.%为了更好地把握香花油茶(Camellia osmantha)采收时机,本研究从9月7日至11月30日,每隔1周采集香花油茶果实对油脂及组分含量进行测定分析,结果表明:香花油茶在整个测定期内鲜出籽率的变化不大,但随着果实成熟度的增加,鲜果干出籽率、干籽出仁率、种仁含油率以及折算的鲜果含油率均呈上升趋势,至11月维持较平稳水平.而脂肪酸组成方面,不饱和脂肪酸的油酸以及饱和脂肪酸的硬脂酸也随着果实成熟度的增加不断上升,而不饱和脂肪酸的亚油酸及饱和脂肪酸的棕榈酸则随着果实成熟度的增加不断下降.11月9日,测定香花油茶鲜果的干出籽率、种仁含油率以及鲜果含油率分别达到33.06%、49.35%和9.25%,均是所有采样中最高的,且脂肪酸组成中不饱和脂肪酸油酸含量也最高.因此,南宁地区香花油茶最适宜的果实采摘时期在11月中旬.
