Gas chromatography-mass spectrometry (GC-MS) determination of phytoconstituents from ethanolic and aqua-ethanolic root extracts of Uraria picta Desv. (Fabaceae)

Abstract

This is a first-time study on Gas Chromatography-Mass Spectrometry (GC-MS) determination of phytoconstituents from ethanolic and aqua-ethanolic root extracts of Uraria picta. It is a commercially importance species which is utilized in Dashmoolarishta, an established ayurvedic drug of ISM. GC-MS determined two major phytoconstituents in ethanolic extract as N-Capric acid Isopropyl Ester (RT- 21.397, 60.98%), 9-Octadecenoic acid (Z) -, Hexyl Ester (RT- 23.298, 39.02%) and three compounds in aqua-ethanolic extract namely Propanoic acid, 2- Hydroxy-, Pentyl Ester (RT- 11.697, 81.64%), α - D-Mannofuranoside, 1-Nonyl - (RT- 20.28, 7.87%) and 2-Bromopropionic acid, Penta decyl ester (RT- 21.486, 6.77%). Four phytocompounds investigated from roots in the present study have commercial significance.
