摘 要 目的:建立同时测定飞蛾藤不同药用部位(茎、嫩枝、叶)中东莨菪苷、东莨菪内酯、绿原酸、隐绿原酸、新绿原酸、异绿原
酸A、异绿原酸B、异绿原酸C等8种成分含量的方法,并进行比较。方法:采用高效液相色谱(HPLC)法。以Agilent TC-C18为色谱
柱,以乙腈-0.1%磷酸溶液为流动相进行梯度洗脱,流速为1.0 mL/min,柱温为30 ℃,检测波长为345 nm,进样量为10 µL。比较飞
蛾藤茎、嫩枝、叶中上述成分的含量并采用Markerlynx XS软件进行主成分分析。结果:东莨菪苷、东莨菪内酯、绿原酸、隐绿原酸、
新绿原酸、异绿原酸 A、异绿原酸 B、异绿原酸 C 检测质量浓度的线性范围分别为 0.076 4~7.64、0.062 8~6.28、0.090 8~9.08、
0.080 0~8.00、0.057 6~5.76、0.094 4~9.44、0.086 0~8.60、0.078 8~7.88 mg/L(r均大于0.999);精密度、稳定性(24 h)、重复性试验的
RSD 均小于 2.0%;平均加样回收率分别为 99.71%(RSD=1.36%,n=6)、100.39%(RSD=1.76%,n=6)、99.20%(RSD=1.75%,
n=6)、100.04%(RSD=2.63%,n=6)、98.57%(RSD=1.99%,n=6)、99.68%(RSD=1.84%,n=6)、99.90%(RSD=1.88%,n=
6)、99.76%(RSD=1.47%,n=6)。上述 8 种成分在茎中的平均含量分别为 9.725 3、1.286 5、7.271 3、1.347 6、0.997 7、0.710 9、
0.656 3、0.364 7 mg/g,在嫩枝中分别为 0.690 3、0.411 7、4.394 3、0.639 6、0.531 3、1.392 7、0.989 1、1.129 2 mg/g,在叶中分别为
1.195 1、0.691 1、27.952 9、6.173 4、1.405 1、0.549 7、0.288 8、0.794 2 mg/g。主成分分析结果显示,飞蛾藤不同部位可分为3类,其
中飞蛾藤茎大部分聚集在得分图的第1象限,嫩枝聚集在第3象限,叶聚集在第4象限。结论:所建方法简便、重复性好,可用于飞
蛾藤不同药用部位中东莨菪苷等8种成分的含量测定。飞蛾藤叶中新绿原酸、绿原酸和隐绿原酸的平均含量相对较高,嫩枝中异
绿原酸B、异绿原酸A和异绿原酸C的平均含量相对较高,茎中东莨菪苷、东莨菪内酯的平均含量相对较高。

ABSTRACT OBJECTIVE:To establish a method for the simultaneous determination of eight constituents,such as scopolin,
scopoletin,chlorogenic acid,cryptochlorogenic acid,neochlorogenic acid,isochlorogenic acid A,isochlorogenic acid B,and
isochlorogenic acid C,in different medicinal parts(stems,twigs and leaves)of Porana racemosa,and to compare the contents of
eight constituents. METHODS:HPLC method was adopted. The determination was performed on Agilent TC-C18 column with
mobile phase consisted of acetonitrile-0.1% phosphate acid (gradient elution) at the flow rate of 1.0 mL/min. The column
temperature was 30 ℃ ,and the detection wavelength was set at 345 nm. The sample size was 10 μ L. The contents of above
constituents in stems,twigs and leaves of P. racemosa were compared,and the principal component analysis was carried out by
Markerlynx XS software. RESULTS: The linear range of scopolin, scopoletin, chlorogenic acid, cryptochlorogenic acid,
neochlorogenic acid,isochlorogenic acid A,isochlorogenic acid B,and isochlorogenic acid C were 0.076 4- 7.64,0.062 8-6.28,
0.090 8-9.08,0.080 0-8.00,0.057 6-5.76,0.094 4-9.44,0.086 0-8.60,0.078 8-7.88 mg/L,respectively(all r>0.999). RSDs of
precision,stability(24 h)and reproducibility tests were all lower than 2.0%. The average recoveries were 99.71%(RSD=1.36%,
n=6),100.39%(RSD=1.76%,n=6),99.20%(RSD=1.75%,n=6),100.04%(RSD=2.63%,n=6),98.57%(RSD=1.99%,
n=6),99.68%(RSD=1.84%,n=6),99.90%(RSD=1.88%,n=6),99.76%(RSD=1.47%,n=6),respectively. The average
contents of above eight constituents were 9.725 3,1.286 5,7.271 3,1.347 6,0.997 7,0.710 9,0.656 3,0.364 7 mg/g in stems;
those were 0.690 3,0.411 7,4.394 3,0.639 6,0.531 3,1.392 7,0.989 1,1.129 2 mg/g in twigs;those were 1.195 1,0.691 1,
27.952 9,6.173 4,1.405 1,0.549 7,0.288 8,0.794 2 mg/g
