| 1 | In vivo and in vitro phytochemical and antibacterial efficacy of Baliospermum montanum (Willd.) Muell.Arg.显示文摘Objective:To evaluate the phytochemical and anti-bacterial potential of mother plants in vivo and in vitro derived callus of Baliospermum montanum(B.montanum)(Willd.) Muell.-Arg. leaves and root.Methods:The in vitro derived rootlets and leaves segments of B.montanum were cut into 0.5-0.7 cm in length and cultured on Murashige and Skoog solid medium supplemented with 3%sucrose,gelled with 0.7%agar and different concentration of 2,4-D either alone or in combinations.The preliminary phytochemical screening was performed by Harborne method.Antibacterial efficacy was performed by well diffusion method and incubated for 24 h at 37℃.Results:The highest percentage of callus formation(leaves segments 86.9±0.56:root segments 78.7±0.51) was obtained on Murashige and Skoog’s basal medium supplemented with 3%sucrose and 2.0 mg/L of 2.4-Dichlorophenoxy acetic acid.The phytochemical study revealed the high quantity presence of steroids,triterpenoids,glycosides,saponins,alkaloids,flavanoids, phenolic compounds,tannins,sugars etc of root and leaves derived calli.The ethanol extract of leaves segment derived calli of B.montanum showed the maximum solubility and antimicrobial activity with the MIC ranged from 100 to 200μL.Conclusions:The preliminary phytochemical study confirmed that the calli mediated tissues showed the higher percentage of metabolite constituents and extraction value compared to the in vivo leaves and roots.The present study observation suggested that a possibility to establish high yielding genotypes by in vitro culture for production of medicinally important bioactive compounds. | Johnson M Wesely EG Zahir Hussain MI Selvan N | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，11： | 6 |
| 2 | Preliminary phytochemical and antimicrobial studies on a spike-moss Selaginella inaequalifolia(hook.& grev.) Spring显示文摘Objective:To screen the anti-cancer spike-mosses for the presence of various bioactivities and to identify the important bioactive chemicals present in Selaginella inaequalifolia(S. inaequalifolia)(Hook.& Grev.) Spring.Methods:Preliminary phytochemical screening was done by following the method of Brindha et al.Antimicrobial study was carried out by disc diffusion method.Results:Results of preliminary phytochemical screening on five different extracts(petroleum ether,benzene,chloroform,ethanol and distilled water) of the spike-moss S.inaequalifolia show the presence steroids,triterpenes,phenolic group,tannin,sugars and catechin.Alkaloids,amino acids,anthraquinone and reducing sugar did not show any positive result.Among the five different extracts,ethanol and chloroform extracts show the presence of maximum number(4 each) of compounds.The results on antimicrobial studies show that all the three microbes[Staphylococcus aureus(S.aureus),Escherichia coli(E.coli) and Candida albicans (C.albicans)]tested are resistant to the ethanol extract and susceptible to petroleum ether extract.The petroleum ether extract shows maximum inhibition with 45 mm of inhibition zone in C.albicans.The inhibition zone in S.aureus and E.coli are 26 mm and 22 mm respectively. Conclusions:The present study shows S.inaequalifolia having potent antibacterial and anticandidal activities. | Varaprasadham Irudayaraj Janaky M Marimuthu Johnson Nallayan Selvan | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，12： | 4 |
