Summary
Betaines, including glycinebetaine and trigonelline, were found in all studied Bromeliaceae plants, though in low concentrations. This research highlights the widespread presence of these compounds in the Bromeliaceae family.
Area of Science:
- Phytochemistry
- Plant biochemistry
- Botany
Background:
- Betaines are important plant metabolites with various physiological roles.
- The Bromeliaceae family is diverse, but its betaine content is not well-documented.
Purpose of the Study:
- To investigate the presence and distribution of betaines in aerial parts of Bromeliaceae species.
- To quantify the levels of glycinebetaine and trigonelline in selected Bromeliaceae taxa.
Main Methods:
- Phytochemical analysis of aerial plant parts from 38 Bromeliaceae taxa.
- Isolation and quantification of glycinebetaine and trigonelline.
Main Results:
- Glycinebetaine and trigonelline were detected in all 38 studied taxa.
- Yields for both betaines were generally low, with glycinebetaine ranging from 0.0004% to 0.087% and trigonelline from 0.0003% to 0.022%.
- Highest yields were observed in Tillandsia usneoides (glycinebetaine) and Billbergia rubicunda (trigonelline).
Conclusions:
- Glycinebetaine and trigonelline are ubiquitous in the aerial parts of the studied Bromeliaceae family.
- The low concentrations suggest these compounds may not be primary storage molecules in this plant family.
