Micropropagation of Calophyllum brasiliense (Cambess.) from nodal segments.
Micropropagation of Calophyllum brasiliense Cambess. (Clusiaceae) is a way to overcome difficulties in achieving large-scale plant production, given the recalcitrant nature of the seeds, irregular fructification and absence of natural vegetative propagation of the species. Cultures were established using nodal segments 2 cm in length, obtained from 1-2 year old seedlings, maintained in a greenh...
متن کاملStorage of Calophyllum brasiliense Cambess. seeds.
Calophyllum brasiliense is a species native to Brazil and has potential for use in the timber industry, in the reforestation of degraded areas, besides having medicinal properties. Its propagation is mainly by seeds which, depending on their recalcitrant characteristics, leads to difficulty in conservation, due to changes in its physiological potential during storage. Aiming to contribute to th...
متن کاملAnti-Mycobacterium tuberculosis activity and cytotoxicity of Calophyllum brasiliense Cambess (Clusiaceae)
We evaluated the in vitro anti-Mycobacterium tuberculosis activity and the cytotoxicity of dichloromethane extract and pure compounds from the leaves of Calophyllum brasiliense. Purification of the dichloromethane extract yielded the pure compounds (-) mammea A/BB (1), (-) mammea B/BB (2) and amentoflavone (3). The compound structures were elucidated on the basis of spectroscopic and spectromet...
متن کاملToxicogenomic analysis of pharmacological active coumarins isolated from Calophyllum brasiliense
Calophyllum brasiliense (Calophyllaceae) is a tropical rain forest tree, mainly distributed in South and Central America. It is an important source of bioactive natural products like, for instance soulatrolide, and mammea type coumarins. Soulatrolide is a tetracyclic dipyranocoumarins and a potent inhibitor of HIV-1 reverse transcriptase and Mycobacterium tuberculosis. Mammea A/BA and A/BB coum...
متن کاملMicropropagation of Alternanthera Sessilis (L.) Using Shoot Tip and Nodal Segments
A rapid in vitro propagation system has been established from mature shoot tip and nodal segments of ahighly valuable medicinal plant Alternanthera sessilis (L.). The explants were cultured on Murashige andSkoog’s medium augmented with different concentrations and combinations of plant growth regulators forshoot bud initiation and multiplications. For shoot tip, highest freque...
