Online published on 24 January, 2020. Abstract A study on physico-chemical properties including powder characters, fluorescence analysis, TLC and HPTLC studies were performed on five (S1 to S5) different powdered market samples of pepper following standard procedures. The samples showed varied texture from very fine to coarse nature. All the samples revealed the presence of diagnostic characters viz., stone cells, starch grains, parenchyma cells etc. The present study revealed that the physico-chemical values were as per standards except for total ash of S2 which is little higher than prescribed. Even though there were variations in the number of spots observed in ethanol extracts among the samples and the text in the Ayurvedic Pharmacopoeia of India, the presence of piperine was confirmed by TLC and HPTLC in all the samples.
