Mogroside Via1, New Isomer of Mogroside VI Isolated From Luo Han Guo
Two isomers of Mogroside VI, Mogroside VIa1 (1) and Mogroside VIa (2), were isolated from the extracts of Luo Han Guo. Compound 1 is a newly isolated isomer of Mogroside VI. We report here detailed structural confirmation of the structures of 1 and 2 as well as the sensory data for both compounds. Structure elucidation of both mogrosides were achieved by NMR analysis and the complete 1H and 13C NMR assignments of both mogrosides are described herein based on the NMR experiments (1H, 13C, COSY, HSQCDEPT, HMBC, ROESY and 1D-TOCSY) and mass spectral data. The sensory properties of compounds 1 and 2 were measured.View article
