Abstract: | Secondary metabolites characterization of ethanol extracts of Palicourea sessilis leaves and stems by UPLC-DAD ESI-MS/MS led to putative identification of hydrolysable tannins in leaf extract (ESI negative mode) while hydroxycinnamic acid amides (HCA) such as N-p-coumaroylputrescine and N-feruloylagmatine were detected in both leaf and stems extracts in the ESI positive mode. Secondary metabolites quantification data showed a higher content of total phenolic in the leaf extract while the total alkaloids contents are statistically equivalent in both of the extracts. Furthermore, monoterpene indole alkaloids were not detected in both extracts. The presence of HCA is here firstly reported for a Palicourea species. This finding increases the classes of secondary metabolites occurring in this genus. |
