Summary

In this paper we describe a simple, precise, and accurate HPTLC method for quantification of lupeol in the bark of Mimosoups elengi (ME). The bark was extracted with hot methanol in a Soxhlet apparatus. Chromatographic separation of the extract was performed on aluminum foil plates coated with silica gel 60 F254 as the stationary phase. The mobile phase was toluene-ethyl acetate-formic acid 12:2:1 (υ/υ). Densitometric evaluation of the separated zones was performed at 220 nm. The lupeol was satisfactorily resolved at R F 0.64 ± 0.02. The accuracy and reliability of the method were assessed by evaluation of linearity (1000–4000 ng per band), precision (method and instrumental precision, as RSD, 1.06 and 1.03%, respectively), accuracy (97.28 ± 0.89), and specificity in accordance with ICH guidelines.
