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.

 Objective: The present study was aimed at phytochemical screening, quantification, and high-performance thin-layer chromatography (HPTLC) analysis of hexane, chloroform and ethanol leaf extracts of Calamus rotang.Methods: Leaf extracts were prepared according to the polarity of the solvents, i.e., hexane, chloroform, and ethanol. Preliminary phytochemical screening involved the qualitative methods to detect the presence of alkaloids, phenols, flavonoids, saponins, steroids, etc. Quantitative estimation of alkaloids using boldine as standard, phenols using gallic acid as standard, and flavonoids using quercetin as standard were done. HPTLC analysis was done with all three extracts along with quercetin and rutin standards using mobile phase for flavonoids, i.e., 90:10 ratio of chloroform and methanol solvents.Results: Phytochemical screening showed the presence of phenols, flavonoids, alkaloids, etc. Hence, quantification was done for these phytochemicals. Alkaloids were present significantly more in hexane leaf extract, i.e., 2.54±0.216mg boldine equivalents/g. Phenols were present significantly more in ethanolic leaf extract, i.e., 49.04±0.364 mg gallic acid equivalents)/g. Flavonoids were present in significant amount in ethanolic leaf extract, i.e., 458.85±5.74 mg quercetin equivalents/g. HPTLC analysis of hexane, chloroform, and ethanolic extracts showed the presence of flavonoids such as quercetin, rutin, and some unknown flavonoid compounds.Conclusion: Ethanolic leaf extract showed a high amount of phenols and flavonoids. Hence, the extract can be further exploited further for in vitro and in vivo research work.

Abstract A simple and reproducible high-performance thin-layer chromatographic method was developed for the simultaneous determination of bergenin and gallic acid in Bergenia ligulata. Water and methanol were used as the extracting solvents. The concentrations of bergenin and gallic acid in both of these solvents were found to be almost the same. The method involves separation of the components by thin-layer chromatography on a precoated Silica Gel 60 F254 plate with a solvent system of ethyl acetate–formic acid–acetic acid–water (100 + 11 + 11 + 27). The sensitivity of the method for bergenin was 0.30 μg, whereas for gallic acid it was 0.25 μg. The proposed method is precise and sensitive and can be used for the detection, monitoring, and simultaneous quantification of bergenin and gallic acid in B. ligulata.
