Study reports on the preparation of oil containing V. negundo extract from different organic solvents and evaluation for anti-inflammatory activity by topical application. The oil obtained was evaluated for anti-inflammatory activity with carrageenan-induced rat paw edema and compared with the marketed sample of mahanarayan oil. The oil extracted using methanol showed highest activity on application compared to all of the oils prepared from other organic solvents. (77)
• Bronchodilatory Effect / Leaves: Study evaluated the mechanisms underlying the effectiveness of V. negundo in hyperactive respiratory disorders. Crude extract of leaves were used to evaluated in vivo bronchodilatory activity in anesthetized rats and underlying mechanisms studies in isolated guinea-pig tracheal strips. Results suggest V. negundo possesses a combination of papaverine-like PDE inhibitor and diltiazem-like Ca(++) entry blocking constituents, which partly explain the bronchodilatory effect. (79)
Anti-Inflammatory / 3.4-Dihydroxybenzoic Acid / Leaves: Study evaluated the anti-inflammatory activity of a leaf extract on topical administration using TPA (tetradecanoylphorbol acetate)-induced mouse ear inflammation model. Bioassay guided chromatography of fractions isolated 3.4-dihydroxybenzoic acid as bioactive principle responsible for the anti-inflammatory activity. (81)
• Antitussive / No Toxicity: Study evaluated the anti-tussive effect of a butanolic extract of V. negundo on sulphur-dioxide-induced cough in mice. At 1000 mg/kg, Vn caused maximum cough-suppresant effects (67% at 60 min). compared to codeine (10 ,mg/kg) and dextromethorphan (10mg/kg) with cough inhibitory potential of 75.7 and74.7%, respectively. LD50 of V. negundo was greater than 5000 mg/kg. In toxicity tests, no signs of neural impairment of acute behavioral toxicity were observed at antitussive doses. Results show an antitussive effect which was devoid of toxicity. (82)
• Bioactive Chromone / Alleviation of Pain and Inflammation: Study of Vitex negundo isolated two new chromone derivatives, namely, methyl 3-(2-(5-hydroxy-6-methoxy-4-oxo-4H-chromen-2-yl)ethyl)benzoate (1) and 3-(1-hydroxy-2-(5-hydroxy-6-methoxy-4-oxo-4H-chromen-2-yl)ethyl)benzoic acid (2). Results showed significant attenuation (p<0.001) of tonic visceral nociception and potent amelioration (p<0.001) of carrageenan-induced paw swelling. Results suggest a potential source of antinociceptive and anti-inflammatory agents. (83)
• Anti-Arthritic Activity Against Denaturation of Protein: Study evaluated the in vitro antiarthritic activity of aqueous extract of V. negundo buy denaturation of protein methods. V. negundo was screened for anti-arthritic activity by denaturation of egg albumin and bovine albumin proteins. Results showed a marked in vitro antiarthritic effect as evidenced by concentration dependent inhibition of protein (albumin) denaturation by aqueous extract of V. negundo. (85)
• Comparative Study of Volatile Constituents / Leaves: Review reports on the chemical profile of volatile oils extracted from leaves of V. negundo. Major constituents were δ-elemene, β-eudesmol, camphor, camphene, carene, β-caryophyllene, caryophyllene oxide, 1,8-cineole [eucalyptol], globulol, linalool, 1-oceten-3 ol, α-pinene, sabinene, terpinyl acetate, 4-terpineol, γ-terpinene, and viridiflorol. Chief constituents were ß-caryophyllene, viridiflorol, and ß-eudesmol. (86)
• Anti-Hemolytic Activity: Study evaluated the phytochemicals, antioxidant properties, and anti-hemolytic activity of Adhatoda vasica and Vitex negundo. Phytochemicals were higher in V. negundo, except for alkaloids. Tannins were high in both plants. The plants showed strong antioxidant and reducing power ability, which supports their use as antioxidant supplement. Both plants prevented hemolysis of goat erythrocytes, and were considered safe and useful for medical formulations. (87)
• Cardiotonic / Leaves: Study evaluated the cardiotonic activity of aqueous extract of leaves of V. negundo using isolated frog heart perfusion technique (IFHP). Results showed significant increase in the height of force of contraction (positive inotropic effect) and decrease in heart rate (negative chronotropic effect) at dose of 0.4 mg. The effect increase as dose was increased. (88)
• Antiestrogenic / Anti-Implantation / Anti-Inflammatory / Leaves: Study evaluated the anti-implantation potential of various fractions of V. negundo leaf extract in female Swiss albino mice. Animals treated with n-hexane fraction showed altered level of superoxide anion radical and superoxide dismutase activity. The possible mechanism of inhibition of blastocyst implantation is through the anti-inflammatory and antiestrogenic potential. (89)
• Antitubercular Activity / Leaves: Study focused on identification, isolation, and characterization of lead constituents and to determine the antitubercular activity of their fractions and isolated compounds. Ethanol extract, petroleum ether, and chloroform fraction showed antitubercular activity at 150 µg/ml. Petroleum ether and chloroform fractions of the EE which contains betulinic acid, ursolic acid, and ß-sitosterol showed anti-TB activity. (90)
