摘要
建立了采用分光光度法石菖蒲中总苯丙素的含量方法,结果表明:标准曲线Y=304.0856x+0.0019,(r=0.9999),平均回收率为98.91%,RSD为0.70%(n=6)。该法测得石菖蒲中总苯丙素的含量为2.3%,该方法灵敏、简便、快速、准确可靠。
We established the method of determinnation of total amino acid in A.tatarinowiiSchott. by Spectrophotometry. The standard curve was Y= 304.0856X+0.0019, (r=0.9999), with average recovery 98.91%,RSD=0.70%(n=6) .The quantitative method is simple,rapid and reliable.
