Spinosic acid A 

Spinosic acid A is a triterpene sapogenin. Spinosic acid A is found in Randia spinosa(Thunb.) Poir.^[1].

Spinosic acid A is 3β,19β-dihydroxyolean-12-en-28-oic acid, with corresponding methyl ester and diacetate derivatives characterised by melting points, optical rotations, IR, NMR, mass spectral, and elemental analysis data^[1].
Oxidation of methyl spinosate A with Jones' reagent produces a mixture of Δ¹²- and Δ¹³(¹⁸)-diketo esters, while oxidation of methyl spinosate A diacetate with sodium dichromate in glacial acetic acid yields 11-oxo-methyl spinosate A diacetate, with both products characterised by melting points, IR spectra, and elemental analysis^[1].
