Cordia obliqua is known as Bumber. Its fruits and leaves are popularly used because of antioxidant and anti-diabetic activities. The purpose of this study is to evaluate the phytochemicals and antioxidant activity as well as botanical features of stem bark of Cordia obliqua. Chemical components were preliminary screened in various fractions based on the polarities including; n-hexane, chloroform, ethyl acetate, butanol and aqueous fractions of using standard procedures. Total phenolic (TPC) and flavonoid (TFC) contents were assessed by Folin-Ciocalteau and aluminium chloride methods respectively. The antioxidant activity was evaluated by ABTS antioxidant procedure, using ascorbic acid as standard. Results confirmed that stem bark of Cordia obliqua chemically is characterized by the presences of flavonoids, alkaloids, steroids, saponins, tannins and carbohydrates at different levels in various fractions and the absence of cardiac glycosides and anthraquinones. Microscopically, the plant is characterized by presence of big Ca oxalate clusters, various types of xylem vessels and big amount of cork cells. TPC was ranged from 13.6{\textpm}1.4 and 220.5{\textpm}3.4 mg GAE/g dry plant extract and TFC was ranged from 0.029{\textpm}0.12and 15.46{\textpm}0.33 mg QE/g dry plant extract. Due to the high phenolic and flavonoid content in butanol and ethyl acetate fractions; results of antioxidant using ABTS assay showed high antioxidant activity with IC50 valued 11.84{\textpm}1.2 μg/ ml for butanol fraction and 14.81{\textpm}1.1 μg/ml for ethyl acetate fraction. Taken together, the research work demonstrated the potential natural antioxidant value of the waste product stem bark of Cordia obliqua. The study endorses forthcoming work to isolate and identify the chemical constituents in stem bark of Cordia obliqua.

Background: Cordia obliqua Willd plant is a genus of flowering plants in the borage family, Boraginaceae. It is also known as clammy cherry. Very little research was carried out for identification of its medicinal importance when compared to other Cordia species Objective: To determine the safe dose and to explore the in vivo antioxidant and hepatoprotective activity of Cordia obliqua fruits Methods: As per our previous study the ethanolic and aqueous extracts were rich in phytoconstituents and exhibited good in vitro antioxidant effect. So the ethanolic and aqueous extracts were used for evaluation of activity. Acute toxicity study (LD50) was conducted according to OECD guidelines. For hepatoprotective activity paracetamol induced hepatotoxicity was studied using standard drug like Silymarin. The antioxidant potential] of the plant extracts were tested using three tests viz, Reduced GSH, Catalase and SOD activity Results: Acute toxicity studies showed the non-toxic nature of Cordia obliqua fruit extract upto dose of 3000mg/kg body weight. Administration of Paracetamol to rats increased the levels of marker enzymes like ALT, AST and ALP. Increase in the levels of these enzymes in serum indicates damage to the liver cells. Pretreatment with aqueous and ethanolic extracts of Cordia obliqua decreased the levels of ALT, AST, ALP and increased levels of total protein, total bilirubin, direct bilirubin and comparisons histology of cells of extract which are an indication for the hepatoprotective activity. Conclusion: The fruits of Cordia obliqua are safe and effective in treatment of hepatic disorders and prevent oxidation of cells.
