Estimation of Embelin in Embelia tsjeriam-cottam Fruits by HPLC to Standardize Harvesting Time
Embelin (2,5-dihydroxy-3-undecyl-2,5-cyclohexadiene-1,4-benzoquinone) is a phenolic compound found in the fruits of Embelia tsjeriam-cottam and is responsible for the medicinal properties of the plant Thus the fruits are harvested at a large scale before maturity leading to depletion of population. Since the chemical constituents of medicinal plants are directly associated with the harvesting time, a study was conducted in different forest areas of Chhattisgarh, India, to standardize the harvesting time of Baividang fruits on the basis of their embelin content during 2005-08. The embelin content was determined by RP-HPLC and varied from 1.09 to 5.21% (w/w). The immature fruits collected in October contain an average of 1.67% embelin whereas mature fruits collected in December on an average contain 4.64% embelin. On the basis of our findings it can be concluded that fruits should be harvested after attaining maturity to get better quality produce and also to maintain the sustainability of plant.
