Plants have formed the sophisticated traditional medicine till today especially in developing countries that use plant-based traditional medicines for their healthcare. The aim of the current review is to present the literature for the pharmacological properties, safety/toxicity studies, and phytochemical investigation of Lannea coromandelica which is popularly known as Indian ash tree. The compiled data may be helpful for the researchers to focus on the priority areas of research yet to be discovered. Particulars of pharmacological activities, phytochemical isolation, toxicity studies etc. were obtained from the published reports....
Roots of Sphaeranthus indicus were extracted with ethanol. The antimicrobial activities of ethanolic extracts were evaluated by using in-vitro disc concentration of 20, 40 and 60 µg/ml. The minimum inhibitory concentration was calculated using broth tube dilution method. Significant antibacterial and antifungal action was observed in ethanolic extract of roots against E. coli, S. aureus, P. aurogenosa by Tetracycline was used as standard and C. albicans, A. niger by Fluconazole was used as standard respectively....
Present review is an attempt to compile the current information on taxonomy, vernacular names, morphology, occurrence and distribution, traditional uses, phytochemistry and pharmacological activities of the Cyathocline lyrata Cass respectively chronologically. This information will be helpful for finding the new chemical entities as well as pharmacological activities....
Recently, natural plants have received much attention as sources of biological active substances including antioxidants. In this present study we investigated In-vitro antioxidant activity of hexane, ethyl acetate and ethanol extracts of Cassia siamea. In-vitro antioxidant activity was evaluated for extracts by using free radicals Superoxide (Riboflavin photo reduction method) and DPPH. The selected plant extracts produced concentration dependent percentage inhibition of different free radicals and produced maximum activity at a concentration of 800 µg and there after the percentage inhibition was raised gradually to its maximum level with higher concentrations. In the present study we found that the extracts of Cassia siamea showed good antioxidant activity. Among the three extracts, ethanol extract showed better activity than the other extracts on the tested super oxide and DPPH free radical....
Ethnomedicine plays a vital role in interiors of North Eastern India till date for basic medicinal needs of the Ethnic Communities of the region. During a preliminary survey, we found a very interesting claim about anthelmintic potential of olive leaves by a local traditional practitioner practicing in the interiors of Brahmaputra Valley region. This research was conducted to evaluate the possible antihelmintic activity of leaf of Olea europea using Indian adult earth worm (Pheretima posthuma) as a test worm. Various concentration (5%, 2.5%, 1%) were in-vitro tested using hydroalcoholic extract and chloroform extract was tested in 0.1% and 0.25% concentrations and the results were involved in terms of time for paralysis (P) and time for death (D). It showed shortest time for paralysis in 5% concentration of Hydroalcoholic extract, while the time for paralysis and death increased in 2.5% and 1% respectively as compared to standard drug Albendazole. The present study indicated that the leaf of Olea europea has a significant anthelmintic potential and can be further explored due to its easy availability and cost factor....
The study aims to evaluate the phytochemical screening and in-vitro antioxidant potential of ethanolic extract of Ocimum sanctum leaves with the help of three in-vitro antioxidant models viz total antioxidant activity (phosphomolybdic acid method),1,1-diphenyl -2-picrylhydrazyl (DPPH) assay and FRAP assay. Ethanolic extract of Ocimum sanctum leaves strongly scavenged DPPH radical scavenging activity, reducing power and total antioxidant activity in dose-dependent manner. The results showed that Ocimum sanctum leaves exhibited strong antioxidant potential with the presence of alkaloids, flavonoids, saponins, tannins, polyphenols and steroids....
The study aims to evaluate the phytochemical screening and free radical scavenging activity of ethanolic extract of Saracaindica bark. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay was used to determine antioxidant properties of Saracaindica by measuring the absorbance at 517 nm. Saracaindica bark and α-tocopherol strongly scavenged DPPH radical in dose-dependent manner. IC50 value for α-tocopherol and Saracaindica bark was found to be 70.97 and 160.34 µg/ml respectively. The results showed that Saracaindica bark exhibited strong antioxidant potential with the presence of alkaloids, flavonoids, saponins, tannins, polyphenols and steroids....
The study aims to evaluate the phytochemical screening and invitro antioxidant potential of ethanolic extract of Tinospora cordifolia leaves with the help of two-invitro antioxidant models viz total antioxidant activity (phosphomolybdic acid method),1,1-diphenyl -2-picrylhydrazyl (DPPH) assay. Ethanolic extract of Tinospora cordifolia leaves strongly scavenged DPPH radical scavenging activity and total antioxidant activity in dose-dependent manner. The results showed that Tinospora cordifolia leaves exhibited strong antioxidant potential with the presence of alkaloids, flavonoids, saponins, tannins, polyphenols and steroids....
The study aims to evaluate the phytochemical screening and free radical scavenging activity of ethanolic extract of Tribulus terrestris. The 1, 1-diphenyl -2-picrylhydrazyl (DPPH) assay was used to determine antioxidant properties of Tribulus terrestris by measuring the absorbance at 517 nm. Tribulus terrestris and α-tocopherol strongly scavenged DPPH radical in dose-dependent manner. IC50 value for α-tocopherol and Tribulus terrestris was found to be 70.97 and 124.08 µg/ml respectively. The results showed that Tribulus terrestris exhibited strong antioxidant potential with the presence of alkaloids, flavonoids, saponins, polyphenols and steroids....
