Antibacterial activity of Tabernaemontana stapfiana britten (Apocynaceae) extracts.
Antibacterial and phytochemical screening of methanolic, sequential extracts (hexane, dichloromethane, ethyl acetate and methanol) and alkaloid rich fractions of Tabernaemontana stapfiana Britten was carried out. The phytochemical screening showed the presence of alkaloids, flavonoids, coumarins, tannins and saponins that have been associated with antimicrobial activity. The stem and root bark ...

Um novo alcalóide, denominado histrixnina (1), e cinco alcalóides indólicos conhecidos, ibogamina (2), olivacina (3) e affinina (4), affinisina (5) e N b -metilaffinisina (6), foram isolados do extrato metanólico das cascas das raízes de Tabernaemontana hystrix. Os triterpenos conhecidos 3O-acetil-α-amirina, 3-O-acetil-β-amirina, 3-O-acetil-lupeol foram também identificados. As estruturas dos c...
متن کاملL-Asparaginase Activity of Fungal Endophytes from Tabernaemontana heyneana Wall. (Apocynaceae), Endemic to the Western Ghats (India)
"Endophytes," the microbes residing within the plant tissues, are important sources of secondary metabolites. Tabernaemontana heyneana Wall., a medicinal tree, endemic to the Western Ghats with rich ethnobotanical history and unique chemical diversity, was selected to study fungal endophytes and evaluate them for L-asparaginase activity. Healthy plant parts were selected for the isolation of en...

متن کاملEffects of Temperature and Season on In Vitro Establishment and Shoot Multiplication of Picea abies (L.) H. Karst
Plant propagation originated from the mature tissues is the most desirable method in producing clonal plants, however microbial contamination usually is the main concern during regeneration processes. Moreover, commercial production of plants using clonal propagation is considered as high throughput method due to the removal of seasonal barriers, lower cost of production with higher yield wh...
