Phytochemistry Profile, Antimicrobial and Antitumor Potential of the Methanolic Extract of Tabernaemontana catharinensis A DC and Eragrostis plana NEES. [PDF]
Natural compounds that have the potential to act as antimicrobials and antitumors are a constant search in the field of pharmacotherapy. Eragrostis plana NEES (Poaceae) is a grass with high allelopathic potential. Allelopathy is associated with compounds generated in the primary and secondary metabolism of the plant, which act to protect it from ...

Leishmanicidal activity of a supercritical fluid fraction obtained from Tabernaemontana catharinensis [PDF]
The branches and leaves of Tabernaemontana catharinensis were extracted with supercritical fluid using a mixture of CO(2) plus ethanol (SFE), and the indole alkaloid enriched fraction (AF3) was selected for anti-Leishmania activity studies. We found that AF3 exhibits a potent effect against intracellular amastigotes of Leishmania amazonensis, a ...

The Occurrence of Intrusive Growth Associated with Articulated Laticifers inTabernaemontana catharinensisA.DC., a New Record for Apocynaceae [PDF]
Premise of research. In Apocynaceae, nonarticulated laticifers have been recorded in most species studied. Interpretation of the mode of development of laticifers, whether articulated or nonarticulated, is controversial, possibly because of the rapid changes that occur in the early differentiation stages of the structures.

In the present work, the technical and economical analysis of extraction and isolation of indole alkaloids from Tabernaemontana catharinensis is presented. The extraction was carried out using supercritical CO2 as solvent and ethanol as cosolvent (5%, v/v). The global yield isotherms were determined at 35 and 45 ◦C for pressures of 150–350 bar.

Cytological differentiation and cell wall involvement in the growth mechanisms of articulated laticifers in Tabernaemontana catharinensis A.DC. (Apocynaceae) [PDF]
The cellular mechanisms of laticifer growth are of particular interest in plant biology but are commonly neglected. Using transmission electron microscopy and immunocytochemical methods, we recorded cytological differentiation and evaluated the cell wall involvement in the growth of articulated laticifers with intrusive growth in the mature embryo and ...
