Sci. 2008, 36( 25) : 10942, 10953 张杨林 傅真治 马建滨, 都玉蓉 ( , 810008) [ 目的] 研究不同海拔高度地区沙棘果中的总黄酮含量[ 方法] 于2007年9 在青海大通甘肃天水山西右玉辽宁建平不同海 拔高度地区采集沙棘果,榨汁后沉淀, 然后将沉淀物在室温下晾干并粉碎, 之后进行超临界萃取, 采用分光光度法对沙棘果中的总黄酮 含量进行测定[ 结果] 青海大通沙棘果的总黄酮含量最高, 为1.27%, 然后依次是甘肃天水沙棘果山西右玉沙棘果辽宁建平沙棘果, 总黄酮含量分别为1.13%0.95%0.89%, 可见, 高海拔地区沙棘果中的总黄酮含量显著高于低海拔地区沙棘果中的总黄酮(P 0. 05) [ 结论]不同海拔高度地区的沙棘果中的总黄酮含量存在明显差异 沙棘; 海拔高度; 总黄酮含量 S793. 6 A 0517- 6611(2008) 25- 10942- 01 Study on Total Flavonoids Content in Seabuckthorn Fruit from Different Altitude Areas MA Jianbin et al ( College of Life a d Geography Scie ce, Qi ghai Normal U iversity, Xi i g, Qi ghai 810008) Abstract [ Objective] The aim was to study the total flavo oids co te t i seabuckthor fruit from differe t altitude areas. [Method] The seabuckthor fruits were collected from differe t altitude areas of Dato g i Qi ghai, Tia shui i Ga su, Youyu i Sha xi a d Jia pi g i Liao i g i September of 2007 a d they were deposited after juici g, the the deposits were aired a d gri ded for the supercritical fluid extractio . The total flavo oids co te t i seabuckthor fruit was detected by the spectrophotometry. [ Result] The total flavo oids co te t i seabuckthor fruit from Dato g i Qi ghai was highest, bei g 1. 27%, followed by that from Tia shui i Ga su, Youyu i Sha xi a d Jia pi g i Liao i g, bei g 1.13%, 0. 95% a d 0. 89% , resp. It ca be see that the total flavo oids co te t i seabuckthor fruit from high altitude area was sig ifica t higher tha that i the low altitude area ( P 0. 05) . [ Co clusio ] The total flavo oids co te t i seabuckthor fruit from differe t altitude areas existed obvious differe ce.
