Pharmacognostic characterization of Carica papaya L.

Abstract

Background: Fruits and leaves of Carica papaya L. are widely used for various therapeutic purposes. This study aimed to establish some pharmacognostic parameters. Materials and Methods: For this propose, determination of total ash values, percentages of water matter, and percentages of total ethanol extractable matter, as well total polyphenol, tannins, and flavonoids were quantify using leaves from different seasons in different years. Results: The samples were cultivated under control. The values of percentage of water matter were: Collet (COL)1 = 5.5 ± 0.06, COL2 = 7.07 ± 0.18, COL3 = 9.03 ± 0.03, COL4 = 11.2 ± 0.46, and COL Mix = 11.5% ± 1.15%; values of percentage of total ethanol extractable matter were COL1 = 12.1 ± 1.4, COL2 = 13.5 ± 1.6, COL3 = 16.7 ± 1.2, COL4 = 11.1 ± 0.55, and COL Mix = 14.1% ± 1%. These values were not different between the samples. The total of flavonoids quantified were for COL1 = 835.6 ± 47.5, COL2 = 1202.9 ± 32, COL3 = 962.4 ± 11.3, COL4 = 708.9 ± 11.4, and COL Mix = 1273.8 ± 45.8. The polyphenol quantified were: COL1 = 11.8 ± 0.3, COL2 = 12.9 ± 0.1, COL3 = 27 ± 0.1, COL4 = 28.4±0.2, and COL Mix = 14.2 ± 0.5. Tannins quantified performed for COL1 = 1.7 ± 0.2, for COL2 = 2.1 ± 0.2, for COL3 = 25.6 ± 0.3, for COL4 = 27 ± 0.3, and for COL Mix = 4 ± 0.6. Conclusions: These results demonstrated that production of secondary metabolites by C. papaya L. is influenced by season conditions, soil and water viability.
