  author={Sulekha Pathak and K. Niranjan and Harish Padh and M. Rajani},
Eugenol and gallic acid are reported from the flower buds of Syzygium aromaticum (L.) Merr. & Perry (clove). Both the compounds have been shown to give interesting biological activities and hence serve as biomarkers. We report a simple TLC densitometric method for the quantification of eugenol and gallic acid in clove. The method was validated for precision, repeatability and accuracy. The method was found to be precise with RSD of 0.61 and 1.3 (intraday) and 0.96 and 0.24 (interday) for… Expand
