Abstract

A pharmacognostical study of Pouteria campechiana (Kunth) Baehni family Sapotaceae was carried out. Literature survey on several Pouteria species was reviewed. A botanical study including macro- and micro- morphological characters of the plant organs were presented for their identification in the entire or powdered forms. Secondary metabolites of Pouteria campechiana organs were analyzed for the first time via high resolution UPLC-PDA-qTOF-MSn which resulted into detection of sixty three chromatographic peaks belonging to various classes. The composition of lipoidal matter was analyzed using GLC technique. Furthermore, chemical analysis was conducted to isolate and identify the major constituents of Pouteria campechiana and resulted into the isolation and identification of ursolic acids, 2Ü, 3Ü, 19Ü, 23 tetrahydroxy ursenoic acid, quercitin, myrcitin, myricetin-3-O-Ý-galactoside and protocatechuic acid for the first time, beside myricetin-3-O-Ü-L-rhamnoside and gallic acid, which were detected before in Pouteria campechiana. Total phenolic and flavonoidal contents were estimated spectrophotometrically in addition to determination of tannin content by hide powder gravimetric method
