Objective: The aim of this study was to evaluate anti-inflammatory activity and cytotoxicity in vitro of hydroalcoholic extract of Bidens andicola.Methods: B. andicola hydroalcoholic extract was obtained from aerial parts of B. andicola, following a standardized methodology. Briefly, aerial parts of B. andicola were extracted with ethanol 70% v/v and defatted with n-hexane, hydroalcoholic fraction was concentrated under controlled conditions in a rotary evaporator, and finally the residue was freeze-drying to obtain the hydroalcoholic extract of B. andicola. Anti-inflammatory activity and cytotoxicity assays were carried out using in vitro isolated neutrophils model using stable water-soluble tetrazolium salts.Results and Conclusions: The in vitro anti-inflammatory assay on isolated neutrophils demonstrated that the hydroalcoholic extract showed antiinflammatoryactivity compared to aspirin, with inflammatory inhibition percent values of 80.138±0.729 to hydroalcoholic extract of B. andicola and 82.117±0.762 to aspirin, each tested in five replicates at the concentration of 200 ppm of hydroalcoholic extract or reference.

Objective: Anacardium occidentale, Achyranthes aspera, and Aegle marmelos are the common plants found in North and South India. The present study identifies the active phytochemicals and antioxidant properties in various extracts derived from dried bark, whole aerial parts, and leaves of the above plants. Materials and Methods: Phytochemical screening included extracts of pet ether, hydroalcoholic, and aqueous. The antioxidant activity was determined by measuring total phenolic contents (TPC), 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity (RSA), and total flavonoid content (TFC). Results: The phytochemical screening of A. occidentale, A. aspera, and A. marmelos of dried bark, whole aerial parts, and leaves revealed the presence of flavonoids, phenols, tannins, and proteins. It also contains alkaloids and glycosides. Hydroalcoholic extract of A. occidentale, A. aspera, and A. marmelos showed highest TPC 0.125 mg/g, 0.256 mg/g, and 0.254 mg/g, respectively. TFCs 0.094 mg/g, 0.145 mg/g, and 0.121 mg/g and highest DPPH RSA with the half maximal inhibitory concentration of 125 μg/mL, 105.58 μg/mL, and 98.89 μg/mL compare to the standard ascorbic acid of 21.65 μg/mL. Conclusion: This study showed that the hydroalcoholic extract of A. occidentale, A. aspera, and A. marmelos is potential source of natural antioxidants.

The Difference

Cadaba farinosa (family Capparidaceae) is generally known as “Indian cadaba” in the traditional ayurvedic system. The current study, aerial parts of different concentrates (Pet.ether, ethyl acetate and methanol) of Cadaba farinose was evaluated for its in-vitro antioxidant potential by Diphenylpicrylhydrazyl radical, and total antioxidant activity taking ascorbate as standard and superoxide radical activity taking Quercetin as the standard for the in-vitro methods. The methanolic concentrates of Cadaba farinose& ascorbic acid exhibited antioxidant potential possessing IC50 208µg/ml & 66µg/ml (Diphenylpicrylhydrazyl radical) , 188µg/ml & 57µg/ml (total antioxidant). The methanolic concentrates of Cadaba farinose & quercetin exhibited antioxidant potential possessing IC50 252µg/ml & 60µg/ml (superoxide radical). The IC50 value was originated that methanolic concentrates of Cadaba farinose more efficient in Diphenylpicrylhydrazyl radical, superoxide radical activity, total antioxidant activity compared EA & PE concentrates. The difference in scavenging potential of the extracts can be due to variation in the percentage of bioactive compound present in different solvents. Invitro antioxidant studies show methanolic concentrates of Cadaba farinose have better antioxidant activity. This result indicates that aerial parts of methanolic concentrate Cadaba farinose could serve as a natural antioxidant, which may be useful in preventing free radical-induced diseases.

Abstract Background Cineraria maritima has a long history of use in the treatment of cataract and other eye-related problems in the homeopathic system of medicines. High oxidative stress is one of the major underlying causes of cataract which results in the precipitation of natural protein present in the lenses with aging. This research has been carried out to determine the anti-cataract activity of C. maritima by performing various antioxidant techniques such as 1,1-diphenyl-2-picrylhydrazyl, nitric oxide, hydrogen peroxide, and studies in oxidative stress–induced ex vivo cataract model. Results Results of the study conducted in the ethanolic extract of aerial parts (leaves and stems) of C. maritima revealed the presence of various phytoconstituents such as alkaloids, phenols, flavonoids, etc. Total phenol and total flavonoid content was found to be 6.31 ± 0.06 % w/w and 2.14 ± 0.09% w/w respectively, which revealed that the plant contains a good amount of these compounds and hence possesses good antioxidant activity. Furthermore, IC50 values obtained from all the methods gave strong evidence regarding the antioxidant potential of this plant. Anti-cataract activity was also investigated using goat eye lenses and promising results were obtained which speak voluminously about its anti-cataract potential and support its well-prescribed use. Conclusion Results obtained with this study clearly supported the significant antioxidant potential and anti-cataract activity of this plant. Further, this plant demands great attention for the development of suitable novel dosage forms for the effective treatment of cataract.
