Abstract:
OBJECTIVE To establish the quality standard of the leaves of Litchi chinensis Sonn.. METHODS The identification of medicinal properties, microscopic characteristics, TLC and content determination method of the leaves of Litchi chinensis Sonn. was conducted. The moisture, total ash, acid insoluble ash and extract of the leaves of Litchi chinensis Sonn. were determined according to Chinese Pharmacopoeia(Volume IV), 2020. RESULTS The leaves of Litchi chinensis Sonn. under forest exhibited specific properties in characteristics, microscopic features and TLC results. The moisture content of the medicinal materials was 2.66%-6.42%, the total ash content was 2.96%-4.52%, the acid insoluble ash content was 0.17%-0.94%, the water soluble extract was 15.38%-19.87%, and the alcohol soluble extract was 24.94%-30.33%. The eight components of gallic acid, protocatechin, catechin, epicatechin, rutin, astragalin, quercetin and kaempferol had a good linear relationship in 0.003 3-0.052 0 mg·mL-1, 0.006 9-0.109 6 mg·mL-1, 0.013 0-0.208 0 mg·mL-1, 0.057 5-0.920 0 mg·mL-1, 0.013 4-0.213 6 mg·mL-1, 0.013 2-0.211 2 mg·mL-1, 0.002 9-0.045 6 mg·mL-1, 0.003 6-0.056 8 mg·mL-1(r>0.999). The average sample recovery rate was 97.43%-102.97% and the RSD was 1.70%-2.90%. CONCLUSION The established quality standard of the leaves of Litchi chinensis Sonn. medicinal material has good specificity, accuracy and reproducibility, which can be used for quality control research of the leaves of Litchi chinensis Sonn..
