LD50 for ethanolic pulp extract was foundto be above 2000mg/kg in Albino rats in vivo[1]
The ethanolic extract of Eugenia jambolana seed extract(100 and 200 mg/kg body weight for 20 days) is found to be toxic to albino rat liver as evident by increase in liver enzyme levels(ALT, gamma GT) and disturbed liver histology[2]
safety of acute(300, 2000, and 5000 mg/kg body weight) and repeated(300, 1000, and 2000 mg/kg body weight, and animals were observed till the 28th day of treatment) oral administration of the aqueous extract of stem bark in Swiss albino mice and Wistar rats in vivo has been demonstrated[3]
LD50 oral for ethanolic seed extract in Swiss albino mice was found to be >5000mg/kg BW. The lowest observable adverse effect level for ethanolic seed extract was found to be 3000 mg/kg BW[4]
Effect on
or Carcinogen-
icity Data:
hydroalcoholic leaf extract showed antimutagenic potential in rats in vivo[5]
Syzygium cummini extract exhibited anti-tumor and anti-oxidative potential against benzo-a-pyrene (BaP)-induced gastric carcinogenesis in mice in vivo[6]
S. cumini seed extract prevented peroxidative damage due to DMBA contributing to skin papillomagenesis in Swiss albino mice in vivo[7]
The in vivo experiments with aqueous seed extract showed significant protective effects against chromosomal damage induced by the genotoxic carcinogens Urethane and DMBA.[8]
Fertility: The administration of the Oleanolic acid from flowers of E. jambolana for 60 days decreased the fertilizing capacity of the male albino rats without any significant changes in body weight or reproductive organ weights[9]
