(Due to misleading nomenclature, the "conception-promoting" property has been attributed to the drug in folk medicine. Its use is possible in vaginal infections and genitourinary diseases, or skin eruptions during pre-conception stage.)The seed kernel on steam distillation yield 0.5% of a sharp-smelling essential oil of the mustard oil type. The oil contains isopropyl and 2-butyl isothio- cyanates as the main constituents and 2-methyl-butyl isothiocyanate as a minor component. The iso-thiocyanates are produced on enzymic hydrolysis of glycosidic progenitors present in the kernels, viz. glucoputranjivin, gluco- cochlearin and glucojiaputin respectively. An additional glucoside, gluco- cleomin has been identified in the seed kernel, it affords a non-volatile mustard oil, cleomin. A glycosidic pattern similar to that in the seed is reported in the shoots and roots.The fruit pulp contains a large proportion of mannitol and small quantities of saponin glucosides and alkaloids.The seed coat gave putranjivoside, putranoside A, B, C and D, beta- sitosterol and tis beta-D-glucoside.The leaves gave amentoflavone and its derivatives, beta-amyrin and its palmite, polyphenols, putranjiva sa- ponin A,B,C, and D and stigmasterol.The bark contains friedelin, friede- lanol, friedelanone, friedelan-3,7-di- one (putranjivadione), 3-alpha-hydro- xy friedelan- 7-one (roxburgholone), carboxylic acid, putric acid, putran- jivic acid.The essential oil from leaves showed mild antifungal activity against Rhizoctonia solani.
