Chemical composition of volatile compounds in flowers and leaves of Senna reticulata (Leguminosae) from the Eastern Amazonia.

Abstract

Senna reticulata (Willd.) H. S. Irwin & Barneby is a Leguminosae’s family plant and native from Amazonia, as known as “matapasto” that means “killspasture” or “shaman’s leaf”, it is utilized as food, medicine, and other uses for the populations of the region. But to it has a lack of information about its constituents, as well as for several other species of plants from Amazonia. So, this research aimed to reveal the chemical composition of the aroma in flowers and leaves of S. reticulata from Eastern Amazonia. Because such information had not yet been presented for the species and may be useful for its better understanding. The aroma of the flowers was a predominance of Geraniol (30.28%), Citronellol (27.87%) and Methyl salicylate (12.91%). While in the leaves was characterized by a mixture of 2E-Hexenal (5.0%) + Hex-(3Z)-enol (67.82%), and by Methyl salicylate (9.81%) and para-vinylGuaiacol (6.14%). The information presented here could contribute for the development of products, based on the chemical composition of the aroma in flowers and leaves from S. reticulata, as well as for future research.
