摘要
以福建省安溪县4月至11月的青钱柳叶片为试验材料,定量分析总三萜质量分数,探究适宜采收的月份。结果表明:总三萜质量分数在4月至11月间存在极显著差异(P<0.01),其中6月、10月总三萜质量分数较高,因此6月、10月为适宜的采收月份。选取总三萜质量分数高的10月,通过UPLC-MS/MS检测青钱柳叶片的萜类物质。结果表明,共检测到69种萜类化合物,其中三萜类化合物占比最高(83.02%),在三萜类化合物中马达积雪草酸、坡模酸、2α-羟基熊果酸、11-酮基-熊果酸、α-香树脂酮、科罗索酸、山楂酸、青钱柳苷Ⅱ、Pterocaryoside B相对含量较高。
The leaves of Cyclocarya paliurus from April to November in Anxi County,Fujian Province were used as the experimental materials to quantitatively analyze the mass fraction of total triterpenoids and explore the appropriate harvesting month.The results showed that the mass fraction of total triterpenoids had a very significant difference from April to November(P<0.01),and the mass fraction of total triterpenoids in June and October was higher,so June and October were the suitable harvesting months.October with the higher mass fraction of total triterpenoids was selected for the detection of terpenes in the leaves of Cyclocarya paliurus by using UPLC-MS/MS.The results showed that a total of 69 terpenoids were detected,and the triterpenoid compound accounted for the highest proportion(83.02%).Among the triterpenoid compounds,Madasiatic acid,Pomolic acid,2α-Hydroxyursolic acid,11-Keto-ursolic acid,α-Amyrenone,Corosolic acid,Maslinic acid,CyclocariosideⅡ,and Pterocaryoside B had higher relative contents.
