The current line of investigation was focused at perusing the presence of phytochemical constituents, investigation of total phenol and flavonoid content, the antioxidant potential of various extracts of Caralluma adscendens whole plant using various in-vitro assays. The dried plant powder was extracted with various solvents based on polarity (Pet ether, Chloroform, Ethyl acetate, Ethanol and Aqueous) by hot continuous extraction in Soxhlet's apparatus and Extracts were dried. Phytoconstituents present in each extract was examined by performing preliminary phytochemical screening. Total Phenolic Content (TPC), Total Flavonoid Content (TFC) and Antioxidant potential for crude extracts were studied by DPPH, nitric oxide scavenging and FRAP methods. The total phenolic content and flavonoid content of Ethanolic extract of plant was found to be 80.08±0.629mg and 70.88±1.170mg of GAE and Quercetin equivalents respectively. The Ethanolic extract exhibited potent antioxidant activity as determined by 2,2-diphenyl-1-picrylhydrazyl(DPPH), nitric oxide scavenging and ferric reducing antioxidant power assays(FRAP) than the other extracts. The IC50 values for the Ethanolic extract of Caralluma adscendens was found to be 214.765±0.224 µg/ml and 215.928±0.506µg/ml by DPPH and nitric oxide scavenging assays respectively.

Olax scandens Roxb. (family Olacaceae) available in throughout tropical India. The current study, aerial parts of different concentrates of Olax scandens was evaluated for its in-vitro antioxidant potential by FRAP assay taking ascorbic acid as the standard and estimation of total phenolic content and flavonoids content. The IC50 value was originated that methanolic concentrates of Olax scandens are more efficient in antioxidant activity by FRAP methods compared EA & PE concentrates. The methanolic concentrates of Olax scandens & ascorbate exhibited antioxidant potential possessing IC50 207µg/ml & 50µg/ml by Ferric reducing ability Power assay. The methanolic and EA concentrates of Olax scandens showed the total phenolic content (14.426 ± 0.032, 4.128 ± 0.025) respectively, and ৒lavonoids content (11.526 ± 0.054, 3.682 ± 0.042) respectively. Invitro antioxidant studies show methanolic concentrates of Olax scandens have better antioxidant activity as well as a higher content of total phenolic and flavonoids content. These results indicate that aerial parts of methanolic concentrates Olax scandens could serve as a natural antioxidant, which may be useful in preventing free radical-induced diseases.

Abstract. Yemata G, Desta B, Fetene M. 2019. In vitro antibacterial activity of traditionally used medicinal plants against Xanthomonas campestris pv. musacearum in Ethiopia. Biodiversitas 20: 555-561. In Ethiopia, traditional medicinal plants have long been used to treat human and livestock ailments. Nevertheless, studies about the use of these plant extracts to control crop diseases are scarce. Therefore, the aim of the present study was to evaluate the antibacterial activity of traditionally used medicinal plants against Xanthomonas campestris pv. musacearum (Xcm). The bioactive chemicals from leaf samples were drawn using methanol by maceration method. Total phenolic content of the extracts was determined by Folin Ciocalteau reagent. The antibacterial activity of leaf extracts was evaluated by disc diffusion method. The phytochemical analysis revealed the presence of alkaloids, flavonoids, phenolic compounds, terpenoids, tannins and saponins. Extracts with higher total phenolic content had greater antibacterial activity. The extract of each species showed antibacterial activity against Xcm on a dose dependent manner. Significant differences were recorded between species and test concentrations. The extract of Bersama abyssinica exhibited the strongest antibacterial activity at 200 mg/mL followed by Ricinus communis, Eucalyptus citriodora and Acokanthera schimperi. At lower test concentrations, extracts of E. citriodora and R. communis revealed higher antibacterial activity. Moreover, these species had lower bacteriostatic and bactericidal concentrations. The results showed the potential potency of E. citriodora and R. communis leaf extracts in controlling enset bacterial wilt. However, further studies on the identification of chemical compounds and in vivo evaluation of the extracts are recommended.

Flavonoid Content

The current investigation is intended to evaluate the content of phytochemical constituents and antioxidant potential of hydroalcoholic extracts of stem and root of Grewia serrulata DC (HAESGS & HAERGS) and leaf and bark of Grewia Nervosa (Lour.) panigrahi (HAELGN & HAEBGN). Initially, all the extracts at different concentrations were estimated for their total phenolic content and total flavonoid content. The study was further extended for their antioxidant potential evaluation using various in vitro methods such as 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical, hydroxyl radical and superoxide radical scavenging assays. The total phenolic content (mg gallic acid equivalent per gram of extract) was high in HAELGN (170.82±0.19) and HAERGS (123.00±0.48) than HAESGS (111.2±0.26) and HAEBGN (119.60±0.23). The total flavonoid content (mg quercetin equivalent per gram) is greater in HAERGS (71.24±0.50) and HAESGS (65.68±0.27) than HAELGN (55.82±0.35) and HAEBGN (62.38±0.45). The IC50 values (µg/ml) of different plant extracts inferred that DPPH radical scavenging activity is greater in HAELGN (42.91±0.88) and HAEBGN (53.87±0.35) than HAESGS (126.73±1.20) and HAERGS (88.87±1.25). However, hydroxyl and superoxide radical scavenging activity is more in HAERGS (135.41±1.19 & 88.00±1.42) and HAELGN (172.28±1.91 & 108.163±1.09) than HAESGS (237.3±1.65 & 110.074±0.87) and HAEBGN (204.7±1.04 & 125.54±1.07). The results of present comprehensive analysis demonstrated that both the plants Grewia serrulata DC and Grewia Nervosa (Lour.) panigrahi possess high phenolic, flavonoid contents and potential antioxidant activity, and could be used as a valid source of natural antioxidants and might be utilized for pharmacological screening of various therapeutic activities.
