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.
