“…Anti-oxidation substances in nature can be divided into two groups (Huang, Ou, & Prior, 2005); (i) the enzymatic group, for example superoxide dismutase (SOD), glutathione peroxidase and catalase, and (ii) the non-enzymatic antioxidants, for example carotenoids, ascorbic acid, a-tocopherol, glutathione and phenolics. With the growing medical interest in natural antioxidants, it is of no surprise that antioxidant proteins in plants have gained attention and reports of their existence and bioactivities have correspondingly increased as well (Arcan & Yemenicioglu, 2007;Ningappa & Srinivas, 2008;Rios-Gonzalez, Erdei, & Lips, 2002;Sarkar, Kinter, Mazumder, & Sil, 2009;Sivapriya & Leela, 2007). Recently, Curcuma longa L., or turmeric, was found to have a potential antioxidant protein, b-turmerine (Smitha, Dhananjaya, Dinesha, & Srinivas, 2009).…”

“…The saponins (1-4) were isolated from ethanol extract of aerial parts of Solanum torvum and evaluated the cytotoxic effect in vitro against a panel of human cancer cell lines (Lu et al 2009). Pharmacological studies revealed that S. torvum possesses antimicrobial (Chah et al 2000;Wiart et al 2004), antiviral (Arthan et al 2002), antioxidant (Sivapriya and Srinivas 2007), analgesic, anti-inflammatory (Ndebia et al 2007), and significant molluscicidal activity .…”

The present study was based on assessments of the antiparasitic activities to determine the efficacies of acetone, chloroform, ethyl acetate, hexane, and methanol dried leaf, flower, and seed extracts of Cassia auriculata L., Rhinacanthus nasutus KURZ., Solanum torvum Swartz, Terminalia chebula Retz., and Vitex negundo Linn. were tested against larvae of cattle tick Rhipicephalus (Boophilus) microplus Canestrini, 1887 (Acari: Ixodidae), adult of Haemaphysalis bispinosa Neumann, 1897 (Acarina: Ixodidae), hematophagous fly Hippobosca maculata Leach (Diptera: Hippoboscidae), nymph of goat-lice Damalinia caprae Gurlt (Trichodectidae), and adult sheep parasite Paramphistomum cervi Zeder, 1790 (Digenea: Paramphistomatidae). All plant extracts showed moderate parasitic effects after 24 h of exposure at 3,000 ppm; however, the highest parasite mortality was found in leaf ethyl acetate, flower methanol of C. auriculata, leaf and seed methanol of S. torvum, seed acetone of T. chebula, and leaf hexane extracts of V. negundo against the larvae of R. microplus (LC(50) = 335.48, 309.21, 297.43, 414.99, 167.20, and 611.67 ppm; LC(90) = 1571.58, 1111.82, 950.98, 1243.64, 595.31, and 1875.50 ppm), the leaf and flower methanol of R. nasutus, leaf and seed methanol of S. torvum, and seed methanol extracts of T. chebula against the nymph of D. caprae (LC(50) = 119.26,143.10,164.93,140.47, and 155.98 ppm; LC(90) = 356.77, 224.08, 546.20, 479.72, and 496.06 ppm), the leaf methanol of R. nasutus, leaf and seed methanol of S.torvum, and seed acetone of T. chebula against the adult of H. bispinosa (LC(50) = 333.15, 328.98, 312.28, and 186.46 ppm; LC(90) = 1056.07, 955.39, 946.63, and 590.76 ppm), the leaf methanol of C. auriculata, the leaf and flower methanol of R. nasutus, the leaf ethyl acetate of S. torvum against the H. maculata (LC(50) = 303.36, 177.21, 204.58, and 211.41 ppm; LC(90) = 939.90, 539.39, 599.43, and 651.90 ppm), and the leaf acetone of C. auriculata, the flower methanol of R. nasutus, the seed methanol of S. torvum, and the seed acetone of T. chebula were tested against the adult of P. cervi (LC(50) = 180.54, 168.59, 200.89, and 87.08 ppm; LC(90) = 597.51, 558.65, 690.37, and 433.85 ppm), respectively. Therefore, this study provides first report on the veterinary parasitic activity of plant extracts from Southern India.

“…Lim et al also isolated a 90 kDa glycoprotein from Opuntia ficus-indica which has been found to lower plasma lipid level by scavenging free radicals [78]. Sivapriya and Srinivas have isolated and purified a novel antioxidant protein from the water extract of Solanum torvum seeds [79]. Park and Lim demonstrated that the 75 kDa phytoglycoprotein isolated from Cudrania tricuspidata Bureau (CTB glycoprotein) shows anti-allergic inflammatory potential by suppressing release of histamine and expression of IL-4 and IFN-G in RBL-2H3 cells [80].…”
