Background: Raphanus sativus is reported to have a variety of biological activities. This work screened the hepato-protective and antioxidant activity of ethanol (ERS), and aqueous (ARS), extracts of leaves of Raphanus sativus in Carbon tetrachloride (CCl 4), model in rats. Material and Methods: The extracts were subjected to antioxidant tests (Total reducing power and Total phenolic content), and preliminary phytochemical screening. A pilot study was done on 100 and 300 mg/kg extracts, form which 300 mg was chosen for further experiments. The albino rats (200-250 grams), were divided into 5 groups of 6 animals each (n=6). There were three control groups comprising of normal control (normal saline-1ml/kg), negative control group (CCl 4 1ml/kg in olive oil in a ratio of 1:1 v/v), and positive control group (Silymarin 50mg/kg). The Test drugs were given in a dose of 300 mg/kg for both ERS and ARS extract for 7 days. Biochemical parameters (AST, ALT, Alkaline phosphatase, Total Bilirubin), histo-pathological examination of liver and in vivo antioxidant tests [CAT, GSH and MDA] were done. Results: The phytochemical study showed the presence of flavanoids, terpenoids, alkaloids, saponins and sterols. A dose dependent increase in the oxidative potential was observed in both the extracts with total phenolic content 70.1 and 44.4 GAE/g extract for ERS and ARS respectively. ERS 300mg/kg showed a significant (p<0.001) increase in levels of AST, ALT and alkaline phosphatase as compared to negative control (percentage hepatoprotection =45.3%) while ARS 300 mg/kg (p<.01) group showed 30% hepatoprotection. The GSH (p<0.001) and CAT (p<0.05) in ERS and ARS were significantly increased while MDA levels were decreased (P< 0.01), as compared negative control. The findings were confirmed histo-pathological examination. Conclusion: The ethanol and aqueous extract of Raphanus sativus have partial hepatoprotection against CCl 4 toxicity.

Purpose: To determine the phenolic and flavonoid contents of R. sativus rhizome ethanol extract and the hepatoprotective effect of the extract in rats. Methods: Folin-Ciocalteau and aluminum chloride colorimetric tests were used to determine the contents of phenols and flavonoids in the R. sativus extract. Male Sprague-Dawley rats induced with CCl4 to develop hepatotoxicity were treated orally with R. sativus extract for 4 weeks. The antioxidant and anti-inflammatory effects of the extract on the liver were determined by evaluating the concentration of oxidative analytes, serum liver enzymes and lipids, and hepatic histopathology and cytochrome P450 2E1 expression. Results: R. sativus extract significantly (p < 0.05) reduced the hepatotoxic effect of CCl4 via its antioxidant activities and protection of liver tissues from oxidative damage. Conclusion: The hepatoprotective effects of R. sativus rhizome ethanol extract are attributed to its high phenolic and flavonoid contents.

Objectives Raphanus sativus (radish) is a species of crucifer, which includes widely consumed vegetables, distributed in Asia, Africa and Europe. It is a rich source of bioactive molecules including anthocyanins, glucosinolates, isothiocyanates and other flavonoids, and miscellaneous phenolic substances. We have evaluated the hepatoprotection of R. sativus extract against zearalenone, an estrogenic mycotoxin initiating hepatotoxicity in male Balb/c mice. Methods Animals were divided into seven treatment groups and treated orally each day for twenty eight days as follows: a control, an olive oil group, group I, group II, and group III treated with radish extract alone (5, 10 and 15 mg/kg, respectively), group IV treated with zearalenone (40 mg/kg), and group V treated with zearalenone plus the lowest dose of radish extract. Key findings Administration of zearalenone alone resulted in significant decreases in the levels of alkaline phosphatase, lactate dehydrogenase, alanine and aspar...

The present study has been carried out to investigate the role of the aqueous extract of the fruits of Pithecellobium dulce (AEPD) against carbon tetrachloride (CCl 4) induced renal oxidative injury in mice. HPLC analysis shows that AEPD contains phenolics, flavonoids and saponins as the major active components. Creatinine and blood urea nitrogen (BUN) levels were assayed to determine renal protective action of AEPD in CCl 4-induced renal pathophysiology. Its antioxidant activity was determined by measuring radical scavenging activity, antioxidant enzymes activities, GSH content, protein carbonylation and lipid peroxidation. In addition, FACS analysis, DNA fragmentation and histological studies were carried out to determine its effect in CCl 4 induced renal oxidative injury and cell death. CCl 4 exposure increased the intracellular reactive oxygen species production, decreased intracellular antioxidant defence, reduced mitochondrial membrane potential, attenuated the intracellular ATP content and caused renal cell death mainly via the necrotic pathway as revealed by DNA fragmentation analysis. Treatment with AEPD both prior and post to the toxin exposure protected the organ from CCl 4 induced oxidative insult. Histological studies also support our results. Combining, results suggest that the protective role of AEPD against CCl 4 induced renal oxidative impairments is probably due to the antioxidative properties present in its active constituents.
Objective: Raphanus sativus is a hugely used edible root vegetable. We investigated whether the feeding of the Raphanus sativus hot water extract (RSE) ameliorates atherogenic lipid profile and oxidative stress in hypercholesterolemia. Methods: After feeding of the RSE to hypercholesterolemic rats for 6 weeks, the levels of plasma and hepatic total cholesterol (TC), triglyceride (TG), and plasma high density lipoprotein-cholesterol (HDL-C) and fecal TC levels were studied. The effects of RSE on the hepatic enzymes, namely alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP), the levels of lipid peroxide (LPO) and liver histology were also evaluated. Results: Hypercholesterolemia increased the levels of TC and TG in the plasma and livers. The levels of ALT, AST and ALP in plasma and LPO in the liver also increased. The dietary RSE, however, significantly ameliorated the above atherogenic lipids and liver enzymes. The RSE significantly reduced the levels of LPO in the liver, suggesting an in vivo protection against oxidative stress. The RSE also inhibited the in vitro Fenton's reagent-induced oxidative stress, thus corroborating the in vivo anti-LPO actions of RSE. The levels of hepatic LPO were positively correlated with plasma AST (r=0.76; P <0.05) and ALT (r=0.43; P<0.05) levels. Histologically, the livers of the RSE-fed hypercholesterolemic rats exhibited lesser fatty droplets and reduced inflammatory cells. Conclusion: Finally, R. sativus extract lowers the cardiovascular disease risk factors under hypercholesterolemic situation by increasing the plasma/hepatic clearance of cholesterol and improving the hypercholesterolemia-induced oxidative damage of hepatic tissues.

Background: Carbon tetrachloride (CCl 4) is a potent nephrotoxin, as it causes acute as well as chronic toxicity in kidneys. Therefore, this study was carried out to assess the pharmacological potential of different fractions of Carissa opaca fruits on CCl 4-induced oxidative trauma in the kidney. Methods: The parameters studied in this respect were the kidney function tests viz, serum profile, urine profile, genotoxicity, characteristic morphological findings, and antioxidant enzymatic level of kidneys. Result: The protective effects of various fractions of C. opaca fruits against CCl 4 administration were reviewed by rat renal function alterations. Chronic toxicity caused by 8-week treatment of CCl 4 to the rats significantly decreased the pH level, activities of antioxidant enzymes, and glutathione contents, whereas a significant increase was found in the case of specific gravity, red blood cells, white blood cells, level of urea, and lipid peroxidation in comparison to control group. Administration of various fractions of C. opaca fruit with CCl 4 showed protective ability against CCl 4 intoxication by restoring the urine profile, activities of antioxidant enzymes, and lipid peroxidation in rat. CCl 4 induction in rats also caused DNA fragmentation and glomerular atrophy by means of dilation, disappearance of Bowmen's space, congestion in the capillary loops, dilation in renal tubules, and foamy look of epithelial cells of tubular region, which were restored by co-admiration of various fractions of C. opaca. Conclusion: Results revealed that the methanolic fractions of C. opaca are the most potent and helpful in kidney trauma.
Hepato and Nephroprotective effects of six important medicinal plants against toxic oxidative stress
Medicinal Plants - International Journal of Phytomedicines and Related Industries, 2023
In the current scenario, consumption of adulterated food, junk food, excessive usage of allopathic medicines, exposure to toxic chemicals and sedentary lifestyle are the primary reasons for the failure of liver and kidney due to oxidative stress. Ayurveda, Indian traditional medicine is becoming popular in view of its safety, no side effects and low cost. Therefore, plant-based medical research has increased all over the world. The plant therapy reduces the oxidative stress in the liver and kidney of experimental animals, the stress induced by toxic chemicals. The supplement of plant extracts either in single or in a combination of various herbal extracts improves the activity of the antioxidative enzymes, reduces the stress markers, normalizes the biochemical parameters and the liver and kidney function. The hepato and nephroprotective ethnopharmacological activities of six medicinal plants like Phyllanthus niruri, Solanum xanthocarpum, polyalthia cerasoides, Acalypha indica, Tinospora cordifolia and Nigella sativa are discussed in the paper.
