Estimation of flavonoids and phenolic constituents of Matricaria Chamomilla L. by HPLC.

[摘要] Chamomile (Matricaria Chamomilla L.) is a well-known medicinal plant species from the Asteraceaefamily often referred to as the "star among medicinal species". Phytochemical screening revealed the presenceof various bioactive secondary metabolites as flavonoids, phenolics, saponins, glycosides, cardiac glycosides,tannins and alkaloids. Anthraquinones and sterols were not detected in the plant. The percentage of inorganicmatter, organic matter, crude fibers content, total carbohydrates, total nitrogen, total proteins, total lipids, totaltannins, total saponins, total alkaloids, total flavonoids, total phenolic of the plant were determined in this study.The flavonoid and phenolic contents of Matricaria Chamomilla L. were analyzed by the HPLC. The quantificationof each compound was done according to the peak area measurements which were reported in calibration curvesof the corresponding standards. The result revealed that Matricaria chamomilla L. consists of flavonoid ofluteolin, apigenin and myricetin (23.1, 15.4 and 8.44 mg/ml) respectively, and phenolic of benzoic acid,Protocatechuic acid and gallic acid (12.5, 8.65 and 5.66 mg/ml) respectively.
