K.ThesisItem Open Access Chemical investigations of capparis decidua edgew fruits(CCSHAU, 2005) Anil Kumar; Dhindsa, Kuldip SinghCapparis decidua is one of the twenty six species of the genus Capparis. It is found under dry conditions. The genus is known for a large number of physiologically active constituents and edible quality of the fruit. The present work was aimed at isolating and identifying the various chemical components present in the fruit of Capparis decidua because the fruit of this plant has not been studied so far. In order to achieve the objective, the fruits of Capparis decidua were procured from village Dhamana, district Hisar. The fruits were crushed and the powered material was refluxed in methanol on a water bath. The methanol extract was concentrated at atmospheric pressure when a dark yellow viscous liquid was obtained. It was mixed with silica gel and subjected to column chromatography to isolate the compounds. Two new compounds namely 14-Hydroxytetradec-12-enylbutanoate and stigmastan-4-one were isolated. The isolated compounds were characterized on the basis of IR, 1H NMR and Mass spectral data.
