Phytochemical Analysis, in vitro Antioxidant and Antidiabetic Activities of Different Solvent Fractions of Maytenus heyneana Root | Chapter 1 | Novel Aspects on Pharmaceutical Research Vol. 5

 Oxidative stress plays an main role in pathogenesis of incessant disease especially CVS affliction (CVD), diabetes, cancer, neurodegenerative ailment hence, the increasing interest in the use of natural antioxidants as healing tools exists. The aim concerning this study was to investigate herbal drug that may enhance useful in the prevention of diabetes and antioxidant potential from intoxicating extracts of Maytenus heyneana (MH) root belonging to the classification Celastraceae and their different parts were studied.Ethanolic extract of Maytenus heyneana root was fractionated into toxin, ethyl acetate, and methanol by liquid-liquid extraction. The preliminary phytochemical reasoning was done by standard designs to identify the ghost of important compounds. In vitro antioxidants exercises were carried by 2,2-diphenyl- 2-picrylhydrazyl (DPPH) and 2,2-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS) cation radical scavenging assays. For antidiabetic potential, α-amylase and α-glucosidase catalyst inhibitory studies were carried on various fractions.The concerning qualities not quantities phytochemical study on the different solvent parts of the roots of MH accompanied the presence of few secondary metabolites to a degree cardiac glycosides, phenols, flavonoids, and terpenoids in all the fractions. Alkaloid was discovered only in chloroform and ethyl acetate parts and saponins were present only in methanol part. The presence of tannins was discovered in ethyl acetate and methanol fractions except in poison fraction. However, steroids and proteins were missing in all the parts.From the results of two assays prominent that at extreme concentration, methanolic fraction presented superior activity than the additional two fractions, even though among the various fractions, the methanol part showed important increase in α-amylase activity (3.14 μg/ml) when distinguished to the standard acarbose (4.67 μg/ml) (p<0.05).it can be decided that the methanol fraction of MH root maybe a good candidature for further studies and the seclusion of active phytoconstituents that is responsible in the management of diabetic and as antioxidant.

Determination of Antioxidant Property of Brown Alga Colpomenia sinuosa | Chapter 02 | Current Topics in Agricultural Sciences Vol. 6

 In vitro studies are a simple, calorimetric qualitative method that may be used to simulate the in vivo system and assist assess the antioxidant activity of Seaweed methanol extracts. DPPH (1,1-diphenyl-2-picryl hydrazyl), nitric oxide radical, hydrogen peroxide, ABTS radical scavenging, and Total antioxidant capacity (TAC) inhibitory assays were used to assess the antioxidant capabilities of Colpomenia sinuosa, a brown alga. In DPPH (96.56 and 88.57 percent), nitric oxide radical (81.2 4.1 percent and 76.69 3.1 percent), hydrogen peroxide (70.7 3.5 and 56.6 2.0 percent), and ABTS (76.8 3.8 percent and 74.0 2.8 percent), the dimethyl sulphoxide (DMSO) and methanol extracts showed the best antioxidant activity. The test for total antioxidant capacity (60.3 4.3 and 57.0 2.0) demonstrated only moderate activity. At a concentration of 2 mg/ml, the activity was higher and equivalent to that of commercial antioxidants butylated hydroxy anisole (BHA) (87.38 1.32 percent) and butylated hydroxy tolune (BHT) (56.05 0.19 percent). Because of its high free radical scavenging action, C. sinuosa could be a viable source of natural antioxidant lead compounds.
