Uptake of Seeds Secondary Metabolites by Virola surinamensis Seedlings. [PDF]
The major secondary metabolites and fatty acids occurring in the seeds of Virola surinamensis were monitored by GC‐MS during germination and seedling development. The role as carbon source for seedling development was indicated considering that both classes of compounds were similarly consumed in the seeds and that no selective consumption of compounds

Establishment of adventitious root cultures of Peritassa campestris (Celastraceae) was achieved from seed cotyledons cultured in semisolid Woody Plant Medium (WPM) supplemented with 2% sucrose, 0.01% PVP, and 4.0 mg L−1 IBA. Culture period on accumulation of biomass and quinone‐methide triterpene maytenin in adventitious root were investigated.

Libidibia ferrea has been used in folk medicine throughout Brazil, and this study evaluated the biological activities of crude extract (CE) as well as a partially purified fraction (F80) obtained from its pods. Results from the MTT assay revealed that only F80 inhibited NCI‐H292 cell growth; however, neither CE nor F80 reduced HEp‐2 cell growth or ...
