Study on quality characteristics of Ligustri Lucidi Fructus in national resource survey and consideration on standards of Ligustri Lucidi Fructus in Chinese Pharmacopoeia / 中国中药杂志

ABSTRACT

The content of tyrosol,salidroside,echinacoside,rutin,acteoside,ligustroflavone,specnuezhenide,and quercetin were determined by HPLC,and the color of Ligustri Lucidi Fructus was determined by comparison with color card.Hundred-seed weight was analyzed by using gravimetric method.The correlation analysis and One-way ANOVA were used to analyze the relationship between the characters,the chemical composition,the harvest time and the geographical location of Ligustri Lucidi Fructus,for giving a comprehensive evaluation of the quality of Ligustri Lucidi Fructus The results showed that 92% of Ligustri Lucidi Fructus were all up to quality standard of Chinese Pharmacopoeia,and the contents of 7 components in Ligustri Lucidi Fructus(except quercetin) were higher than those in samples with black colors.The content of salidroside in Ligustri Lucidi Fructus harvested in June was the highest and the other7 components of Ligustri Lucidi Fructus were relatively high in 8-10 months.According to the quality parameters of Ligustri Lucidi Fructus,the Ligustri Lucidi Fructus from six habitats can not be distinguished effectively.The results showed that there was a certain relationship between the color,harvest season and component content of Ligustri Lucidi Fructus,and the habitats were not related to the quality parameters of Ligustri Lucidi Fructus.The study aimsat providing data support for the resource status of native Ligustri Lucidi Fructus,and a theoretical basis for the revision of standards of Ligustri Lucidi Fructusin the future.
