Abstract

Stevia rebaudiana Bertoni, a plant originating in Paraguay, produces a variety of high-potency, low calorie sweeteners in its leaf tissue. The essential oil composition of the aerial parts of five different Stevia rebaudiana genotypes cultivated in Tuscany coast (Italy) were examined by GC and GC/MS. Forty different components were identified and the main constituents in all studying samples were spathulenol (13.4-40.9%), caryophyllene oxide (1.3-18.7%), β-caryophyllene (2.1-16.0%) and β-pinene (5.5-21.5%).

Abstract

An HPLC-ESIMSn method, based on high-performance liquid chromatography coupled to electrospray positive ionization multistage ion trap mass spectrometry, has been used to rapidly identify and guide the isolation of phenolic constituents from the methanol extract of the aerial parts of T. cinerea. On the basis of the results of the online screening by HPLC-ESIMSn, 17 phenolic constituents, including two new compounds, namely demethylapollinin 7-O-β-D-glucopyranoside (1) and cineroside A (17), were isolated, and their structures were unambiguously assigned by the extensive use of 1D- and 2D-NMR experiments.
