4. Conclusion
About forty phenolic compounds were detected in polar extracts
of wild R. grandifolius Lowe (leaves, flowers and berries) such as
flavonoids, anthocyanins, glycosylated triterpenes and conjugated
forms of hydroxycinnamic acids. Twenty five compounds were
found in leaves and flowers and seventeen in berries, these comprising
six anthocyanins; two procyanidins were found in leaves.
Six triterpene glycosides were ubiquitous in the various morphological
parts.
