Herbal beverages with desirable sensory attributes are an ideal way to offer consumers with phytochemicals having specific health promoting functionalities. Syzygium cumini bark decoction is used in treating diabetes mellitus in Ayurveda medicine. This work attempted to prove the presence of antidiabetic compounds in the S. cumini decoction and the ready to serve (RTS) herbal drink developed using the decoction. Activity guided fractionation of the decoction of the S. cumini was carried out by sequential extraction with organic solvents of different polarities. Thin Layer Chromatography (TLC) with authentic compounds and HPLC were performed for identification and confirmation of the compounds in the decoction and the RTS herbal drink. Presence of gallic and ellagic acids in the decoction and RTS herbal drink was proven and confirmed with HPLC. The LC UV-VIS spectra of the two compounds were identical with the corresponding spectra of the library. Further, gallic acid and umbelliferone were determined as the active compounds in the decoction by TLC and were confirmed by cochromatography with authentic compounds. The present investigation confirmed the presence of gallic acid, ellagic acid, and umbelliferone which are proven to have antidiabetic activities in the decoction and the RTS herbal drink prepared with the decoction.

Abstract Whole plant of Phyllanthus amarus Linn. is a reputed drug of the Indian systems of medicine that is used as hepatoprotective agent. A simple high-performance thin-layer chromatography (HPTLC) densitometric method has been developed for the simultaneous quantitation of phyllanthin, hypophyllanthin, gallic acid, and ellagic acid in the whole plant of P. amarus. They were found at levels of 0.37, 1.16, 0.36, and 0.17% (w/w), respectively. The method was validated for precision, repeatability, and accuracy. Instrumental precision was found to be 0.54, 0.93, 0.08, and 0.78% (coefficient of variation, CV); repeatability of the method was 1.01, 0.79, 0.98, and 1.06% (CV) for phyllanthin, hypophyllanthin, gallic acid, and ellagic acid, respectively. Accuracy of the method was determined by a recovery study conducted at 3 different levels, and the average recovery was found to be 99.09% for phyllanthin, 99.27% for hypophyllanthin, 98.69% for gallic acid, and 100.49% for ellagic acid. The proposed HPTLC method was found to be simple, precise, specific, sensitive, and accurate and can be used for routine quality control of raw material of P. amarus and formulations containing P. amarus. It also has the applicability in quantitating any of these marker compounds in other drugs.
