| 1 | Antibacterial activity of leaves and inter-nodal callus extracts of Mentha arvensis L显示文摘Objective:To determine the anti-bacterial efficacy of chloroform,ethanol,ethyl acetate and water extracts of inter-nodal and leaves derived calli extracts from Mentha arvensis(M.arvensis) against Salmonella typhi(S.typhi),Streptococcus pyogenes(S.pyogenes),Proteus vulgaris(P. vulgaris) and Bacillus subtilis(B.subtilis).Methods:The inter-nodal and leaves segments of M.arvensis 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-Dichlorophenoxyacetie acid(2,4-D) either alone or in combinations.The preliminary phytochemical screening was performed by Brindha et al method.Antibacterial efficacy was performed by disc diffusion method and incubated for 24 h at 37℃.Results:Maximum percentage of callus formation(inter-nodal segments 84.3±0.78;leaves segments 93.8±1.27) was obtained on Murashige and Skoog’s basal medium supplemented with 3%sucrose and 1.5 mg/L of 2,4-D.The ethanol extracts of leaves derived calli showed the maximum bio-efficacy than other solvents.The leaves and stem derived calli extracts on Proteus sp.showed that the plants can be used in the treatment of urinary tract infection associated with Proteus sp.Through the bacterial efficacy studies,it is confirmed that the in vitro raised calli tissue was more effective compared to in vivo tissue.Conclusions:The bio-efficacy study confirmed that the calli mediated tissues showed the maximum zone of inhibition.The present study paved a protocol to establish high potential cell lines by in vitro culture. | Johnson M Wesely EG Kavitha MS Uma V | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，3： | 9 |
| 2 | Chromatographic finger print analysis of steroids in Aerva lanata L by HPTLC technique显示文摘Objective:To determine the chemical profile and steroids composition of the medicinally important plant Aerva lanata(A.lanata) L.Methods:Preliminary phytochemicul screening was done by the method as Harborne described.HPTLC studies were canied out as Harborne and Wagner et al described.The Ethyl acetate-ethanol-water(8:2:1.2) was employed as mobile phase for glycosides.Results:The desired aim was achieved using Chloroform-acetone(8:2) as the mobile phase.The methanolic extract of stem,leaves,root,flower and seeds of A.lanata showed the presence of 30 different types of steroids with 30 different Rf values from 0.04 to 0.97. Maximum number(11) of steroids has been observed in leaves followed by root(10).Conclusions: HPTLC profile of steroids has been chosen here to reveal the diversity existing in A.lanata.Such finger printing is useful in differentiating the species from the adulterant and act as biochemical markers for this medicinally important plant in the pharma industry and plant systematic studies. | Yamunadevi Mariswamy Wesely Edward Gnaraj Johnson M | 2011 | Asian Pacific Journal of Tropical Biomedicine2011，1，6： | 6 |
| 3 | 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 |
