Abstract

Diospyros kaki L.f. fruit and leaves are traditionally used for the treatment of hypertension, angina, internal hemorrhage, antithrombotic and anti-inflammatory effects.In the current study, the protective effects of ethyl acetate (Per-1), n-butanol (Per-2), and aqueous (Per-3) fractions of Diospyros kaki leaves against carbon tetrachloride (CCl4) induced nephrotoxicity in Swiss albino rats were tested. Animal were divided into nine groups; each group consists of six animals. The groups were : group I was untreated and kept as control, group II was treated with CCl4 only, group III (silymarin with CCl4); group IV (Per-1 100 mg/kg with CCl4);group V (Per-1 200 mg/kg with CCl4); group VI (Per-2 100 mg/kg with CCl4); group VII (Per-2 200 mg/kg with CCl4); group VIII (Per-3 100 mg/kg with CCl4); and group IX (Per-3 200 mg/kg with CCl4). Silymarin was used as standard drug. All tested fractions were found active (except Per-1 at low dose of 100 mg/kg) with significant value (p < 0.001) compared to CCl4 only group. Serum creatinine, malondialdehyde (MDA), and uric acid were significantly (p < 0.001) lowered in group VII–IX as compared to CCl4 only group. Similarly, total protein (TP) and non-protein sulfhydryls(NP-SH) level in kidney tissues were significantly (p < 0.001) elevated in the same groups compared to CCl4 only group. Further to check the cardio-protective potential, biochemical parameters such as LDH, creatine kinase, TP, MDA, and NP-SH levels in myocardial tissues were also estimated.These findings confirmed that the n-butanol and aqueous fractions are active and recommended for further bioactive phytoconstituents screening. Repeated column chromatography on silica gel G and sephadex-LH-20 of the active n-butanol fraction, four flavonoids were isolated. Based on the spectroscopic NMR data, compounds were identified as kaempferol (1), quercetin (2), astragalin (3), and rutin (4).
