Phytochemical Investigation on Volatile Compositions and Methoxylated Flavonoids of Agrostis gigantea Roth.

ABSTRACT: In this study, methoxylated flavonoids and volatile constitutions of Agrostis gigantea Roth (Poaceae) were investigated for the first time. The flavonoids were identified by spectroscopic methods (¹H-NMR, ¹³C-NMR, COSY, NOSEY, TCOSY, and HMBC). The volatile constitutions of aerial parts and seeds were analyzed by gas chromatography-mass spectrometry (GC-MS). Two methoxylated flavonoids, luteolin 5-methyl ether (1), and cirsilineol (2) were isolated from the aerial parts of this plant. According to the GC-MS data the main constitutions of these volatile oils belong to the simple phenolic category which include coniferyl alcohol (18.80%) and eugenol (12.19%) in aerial parts and seeds, respectively. By using the computer- aided molecular modeling approaches, the b
