Abstract:
ObjectiveTo investigate the quality of Ligustri Lucidi Fructus in the market， and the moisture， extract， determination of Zhuyao and Douchi Ligustri Lucidi Fructus were compared to increase the utilization rate of Ligustri Lucidi Fructus. MethodThe properties， moisture， total ash， alcohol-soluble extract content and thin layer chromatography （TLC） identification were determined by the methods of Ligustri Lucidi Fructus included in the 2020 edition of Chinese Pharmacopoeia， and high performance liquid chromatography （HPLC） fingerprint and determination of specnuezhenide and salidroside were established with the mobile phase of 0.2% phosphoric acid aqueous solution （A）-acetonitrile （B） （0-70 min， 92%-65%A） for gradient elution， and the detection wavelength of 220 nm at 0-14 min and 225 nm at 14-70 min. The two different characters of Ligustri Lucidi Fructus were comprehensively compared by the above indicators. ResultExcept for one batch which did not meet the requirements due to the quality of harvesting， the other 12 batches of samples all met the requirements of the 2020 edition of Chinese Pharmacopoeia， but there were two different characters. Comparing the two different characters of Ligustri Lucidi Fructus， it is found that the moisture， total ash， extract， salidroside and specnuezhenide contents of Zhuyao samples were 2.22%-5.19%， 3.91%-4.49%， 32.56%-40.95%， 0.073%-0.170% and 1.45%-4.14%， and these values of Douchi samples were 3.57%-5.61%， 3.65%-4.44%， 41.31%-46.70%， 0.041%-0.067% and 3.01%-4.20%， respectively. ConclusionThe contents of extract and specnuezhenide of Douchi Ligustri Lucidi Fructus are mostly higher than those of Zhuyao Ligustri Lucidi Fructus， while the content of salidroside is lower than that of Zhuyao samples， and there are no significant differences in moisture， TLC identification and total ash content. Based on the above research， if the main purpose is to extract salidroside， it is recommended to choose Zhuyao Ligustri Lucidi Fructus. If the main purpose is to use Ligustri Lucidi Fructus as medicine， it is recommended to choose Douchi Ligustri Lucidi Fructus.
