Variation of the alkaloid content of Peumus boldus (boldo).
TLDR
The alkaloid composition of the leaves of Peumus boldus, determined for 130 individually identified trees, classified by age and sex, was highly variable, where N-methyllaurotetanine, laurotetsine, coclaurine and in some cases isocorydine predominated, but not boldine. Expand
PHYTOCHEMICAL ANALYSIS OF ALKALOIDS FROM THE CHILEAN ENDEMIC TREE CRYPTOCARYA ALBA
TLDR
A phytochemical study of the roots and aerial parts of Cryptocarya alba (Mol.) Looser (Lauraceae), an endemic Chilean tree, led for the first time to the isolation and unambiguous characterization of four known alkaloids by NMR techniques. Expand
Boldine inhibits the alveolar bone resorption during ligature-induced periodontitis by modulating the Th17/Treg imbalance.
TLDR
Boldine, administered orally, inhibited the alveolar bone resorption and modulated the Th17/Treg imbalance during experimental periodontitis, which is reported to protect from pathological bone loss during rheumatoid arthritis and osteoporosis. Expand
Variation of Secondary Metabolites in the Aerial Biomass of Cryptocarya alba
TLDR
Important variations were found according to the season, age of the tree and of the leaves, and the EO composition also varied considerably, supporting the idea that the natural variability of medicinal species is an important subject for study. Expand
