Boerhaavia diffusa L. is a perennial creeping weed contains 15 amino acids, including 6 essential aminoacids and a large number of such compounds as flavonoids, alkaloids, steroids, triterpenoids, lipids, lignins, carbohydrates, proteins, and glycoproteins. The concentrations are set as 0.05%, 0.1%, 0.15% and 0.2 % using petroleum ether and ethyl alcohol extract of stem. The duration of the treatment is 30 minutes prior to mitotic peak. The mitotic index and index of various stages of mitosis are scored along with the number of abnormal cells.
