目的:对黑果枸杞的化学成分进行定性鉴别。方法:采用化学成分系统预试法,对黑果枸杞的水提取液、乙醇提取液、石油醚提取液中化学成分进行定性鉴别。结果:通过系统预试验,提示黑果枸杞中可能含有氨基酸、糖类、皂苷、有机酸或酚类、黄酮、三萜类、生物碱和花青素等成分。结论:系统预试验完成了黑果枸杞中化学成分的定性鉴别,为进一步研究该植物的生物活性成分提供了理论基础。 Objective: To qualitatively identify the chemical constituents of Lycium barbarum. Methods: The chemical constituents in aqueous extract, ethanol extract and petroleum ether extract of Lycium barbarum were qualitatively identified by the chemical composition system pre-test method. Results: Through the system pre-test, it is suggested that the black berries may contain amino acids, sugars, saponins, organic acids or phenols, flavonoids, triterpenoids, alkaloids and anthocyanins. Conclusion: The system pre-test completed the qualitative identification of the chemical constituents of Lycium barbarum, which provided a theoretical basis for further study of the bioactive components of the plant.
