Phenylpropanoid and phenylethanoid derivatives from Kigelia pinnata DC. fruits

Abstract

Further phytochemical investigation of the fruits of Kigelia pinnata DC. has yielded a new phenylpropanoid derivative identified as 6-p-coumaroyl-sucrose (1) together with ten known phenylpropanoid and phenylethanoid derivatives (2–11) and a flavonoid glycoside (12). The structures of the isolated compounds were elucidated using various techniques of NMR and MS spectral analysis.

Keywords:

• Kigelia pinnata DC.
• Phenylpropanoids and phenylethanoids
