TITLE:
摘要: 目的:建立同时测定桑白皮中新绿原酸、桑皮苷A、绿原酸、紫云英苷、桑根酮C和桑辛素等6种活性成分含量的方法,为完善桑白皮的质量控制标准提供参考。方法:采用高效液相色谱法。色谱柱为Agilent 5 TC-C18,流动相为乙腈-0.1%甲酸(梯度洗脱),流速为1 mL/min,检测波长为280 nm。结果:新绿原酸、桑皮苷A、绿原酸、紫云英苷、桑根酮C和桑辛素检测质量浓度的线性范围分别为0.001 06~0.042 4、0.001 67~0.066 8、0.007 95~0.318、0.001 65~0.066 0、0.005 00~0.200和0.001 24~0.049 6 mg/mL(r均≥0.999 6),定量限分别为0.11、0.14、0.81、0.17、0.45和0.12 μg/mL,检测限分别为0.04、0.05、0.41、0.07、0.18和0.04 μg/mL,精密度试验的RSD分别为0.26%、0.31%、0.24%、0.27%、0.36%和0.44%(n=6),稳定性试验的RSD分别为0.68%、0.54%、0.62%、0.53%、0.41%和0.73%(n=6),平均方法回收率为99.1%、98.8%、98.8%、98.4%、98.5%和99.9%(RSD为0.5%~1.5%,n=9)。结论:该法简便、准确,可用于桑白皮中6种活性成分的同时测定。
ABSTRACT: OBJECTIVE: To establish the method for the simultaneous determination of content of 6 active components as neochlorogenic acid, mulberroside A, chlorogenic acid, astragalin, sanggenon C and morusin in Morus alba, and to provide reference for improving quality control standard of M. alba. METHODS: HPLC method was adopted. The determination was performed on Agilent 5 TC-C18 with mobile phase consisted of acetonitrile-0.1% formic acid (gradient elution) at the flow rate of 1 mL/min. The detection wavelength of 280 nm. RESULTS: The mass concentration linear range of neochlorogenic acid, mulberroside A, chlorogenic acid, astragalin, sanggenon C and morusin were 0.001 06-0.042 4, 0.001 67-0.066 8, 0.007 95-0.318, 0.001 65-0.066 0, 0.005 00-0.200 and 0.001 24-0.049 6 mg/mL, respectively (all r≥0.999 6); the limits of quantitation were 0.11, 0.14, 0.81, 0.17, 0.45 and 0.12 μg/mL, respectively; the limits of detection were 0.04, 0.05, 0.41, 0.07, 0.18 and 0.04 μg/mL, respectively; RSDs of precision test were 0.26%, 0.31%, 0.24%, 0.27%, 0.36% and 0.44% (n=6), respectively; RSDs of stability test were 0.68%, 0.54%, 0.62%, 0.53%, 0.41% and 0.73%(n=6), respectively; average method recovery rates were 99.1%, 98.8%, 98.8%, 98.4%, 98.5% and 99.9%(RSDs were 0.5%-1.5%, n=9), respectively. CONCLUSIONS: The method is simple, accurate, and can be used for simultaneous determination of 6 active components in M. alba.
