This crude drug showed the characteristic physicochemical values such as moisture content (13.11%), extractable matter in ethanol at 70% (13.53%), total ashes (3.45%), water soluble ashes (2.43%) and acid insoluble ashes (0.64%). Phytochemical screening revealed the possible presence of alkaloids, oils and/or fats, coumarins, saponins, flavonoids, pyrogallol-type tannins, quinones, catechins, reductants sugars, triterpens and steroids and absence of resins, aminoacids, cardiotonic glycosides, anthocyanidins and astringent and/or bitter principles, realized under WHO parameters.展开更多

Petals of genus Talipariti are rich source of secondary metabolites and most of these metabolitesare reported to possess expectorant, antasthmatic, appetitive, antioxidant, and antibacterial properties. Hence, in our study, we present avalidated, sensitive, reliable, and cheap narrow-bore UHPLC-UV-ESI-MS/MS coupled to PDA （photodiode array detectors） methodfor the simultaneous isolation and identification of flavonoids and their glycosidic derivatives in this flower drug. In addition, abouttwelve compounds were identified in this specie based on chromatography retention time （tR）, UV and MS/MS spectra and comparedwith those of isolated authentic compound and literature data. About eighth constituents were reported for the first time from Taliparitielatum. Our results demonstrated the developed method could be employed as a rapid and versatile analytical technique foridentification of chemical constituents and quality control of Talipariti elatum.展开更多
