ABSTRACT
The present study was aimed to elucidate antihyperlipidemic effect of ethanolic extract of bark of Dolichondrone falcata Bignoniaceae family by alloxan-induced hyperlipidemia in albino wistar rats and to investigate the serum lipid levels. Hyperlipidemia was induced experimentally in rats by inducing alloxan at a dose of 150mg/kg body weight. Hyperlipidemic rats were administered fresh ethanolic root extract at the dose of 200mg/kg b.w and 300mg/kg b.w and the standard drug Atorvastatin 10mg/kg b.w. Blood samples were collected after 24hrs of last administration and used for estimation of lipid profile. Serum cholesterol levels were estimated using standard methods. Fresh ethanolic extract at a dose of 200mg/kg b.w and
300mg/kg b.w resulted in dose dependent significant decline in total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C) and very low density lipoprotein-cholesterol (VLDL-C). Further, in comparison to atorvastatin 10mg/kg resulted in comparable decrease of total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C) and very low density lipoprotein-cholesterol (VLDL-C) levels. The phytochemical analysis revealed the presence of flavonoids, triterpenoids, alkaloids, phenolic compounds, tannins and saponins. The results of present study revealed antihyperlipidemic effect of Dolichondrone falcata in alloxan induced rats.
