INVESTIGATION OF PHYTOCHEMICAL CONSTITUENTS, PHYSICOCHEMICAL PROPERTIES AND ANTIMICROBIAL ACTIVITIES FROM THE LEAVES OF SEA AURICUATA (L.) ROXB.
Abstract
- The plant Senna auriculata (L.) Roxb., belong to the family Fabaceae (former Caesalpiniaceae ). It is widely distributed in Myanmar. This plant is one of the famous medicinal plants that found in Mandalay, Magway and Sagaing Regions. In this paper, the preliminary phytochemical tests, physicochemical properties, nutritional value and antimicrobial activities of Senna auriculata (L.) Roxb. have been described. In Morphological study, this plant is a shrub which has cylindrical stem, brown in colour with several branches. The leaves are paripinnately compound with auriculate stipules. Inflorescences terminal or axillary, corymbose racemes, flowers are bright yellow. The fruits are oblongoid pods and flattened. The powdered leaves were tested for the phytochemical constituents and physicochemical properties. Alkaloid, glycoside, carbohydrate, -amino acid, phenolic compound, flavonoid, terpenoid, steroid, tannin and reducing sugar were present but cyanogenic glycoside, starch and saponin were absent in samples. According to physicochemical examination, the powder of leaves were most soluble in water and moderately soluble in ethanol and methanol. The nutrient content of leaves were also studied. It revealed that the presence of protein, crude fiber and crude fat. Antimicrobial activities of Senna auriculata ( L.) Roxb. were also tested by using agar-well diffusion method with six pathogenic microorganisms. In this experiment, acetone extract of leaves showed the most effective activities against Pseudomonas aeruginosa , Bacillus pumalis and Escherichia coli . The ethanol extract showed more antimicrobial activities against Bacillus subtilis and Candida albicans. Senna auriculata (L.) Roxb was observed to have antimicrobial activity and can be used for medicinal purposes.
