摘　　要：从广东产的3个甘蔗品种(22、356和727号)的表皮和茎上收集蔗蜡;以蔗蜡为原料,通过精制、皂化水解、萃取、脱色精制等步骤得到3种多廿烷醇。采用气相色谱(GC)分析方法对3种多廿烷醇中的高级脂肪醇的种类和含量进行定性和定量分析。结果表明,3个品种的蔗蜡精制多廿烷醇得率分别为45.6%,46.8%和50.3%。3种精制多廿烷醇组分比例类似,均以二十八烷醇为主要组分,其含量为61.58%~66.87%,同时含16.97%~18.22%二十六烷醇和3.83%~4.09%三十烷醇。Sugarcane wax was collected from the cuticle of three sugarcane varieties(No.22,No.356 and No.727)produced in Guangdong.Three kinds of policosanol samples were obtained from cane wax by refining,saponification hydrolysis,extraction and decolorization.The qualitatively and quantitatively of three policosanol samples were analyzed by gas chromatography(GC).The results indicateed that the yield of refined policosanol was 45.6%,46.8%and 50.3%,respectively.The proportion of the three refined docosanol components was similar,with 61.58%-66.87%of octacosanol as the main component,16.97%-18.22%of hexacosanol and 3.83%-4.09%of triacontanol.
