Mohammed Ali*, Shahnaz Sultana and Showkat Rassol Mir
Capparis decidua (Forssk.) Edgew. (family Capparaceae) is a branching shrub or small tree found in the subtropical and tropical regions of southern Asia and Africa. The plant aerial parts are used to treat asthma, anorexia, boils, bruises, cardiac troubles, constipation, cough, diabetes, diarrhoea, dysentery, intermittent fever, jaundice, joint pain, liver infections, lumbago, parasitic worms, piles, pyorrhoea, renal disorders, rheumatism, skin diseases, swellings, toothache, indolent ulcers and wounds. Our study was planned to isolate chemical constituents from a methanolic extract of the aerial parts of C. decidua and to characterize their structures on the basis spectral data analysis. Phytochemical investigation of the aerial parts of C. decidua led to isolate five new chemical constituents as a saturated aliphatic keto alcohol identified n- docosan-1-ol-14-one (1), an aliphatic alcohol viz., n-tricosan-9β-ol (2), a sesquiterpenoid lactone formulated as germacr-3β-ol-12-ene-D-6,14-olide-15-oic acid (3), a polyamino- alkaloid characterized as 14, 15-didemthyl capparidisine (4) and a steroidal ester , viz. stigmast-5-en-3β-ol-3β-n-octacos-13ʹ(Z)-enoate (β-sitosterol 3β-n-octacos-13ʹ(Z)-enoate, 5) along with a known disaccharide identified as β-D-fructofuranosyl-(1→2)- O-α-D-glucopyranoside (sucrose, 6).
Keywords: Capparis decidua, aerial parts, phytoconstituents, isolation, characterization.
