Six new glucose esters of 3-nitropropanoic acid from Indigofera kirilowii

An investigation of the aliphatic nitrocompounds in Indigofera kirilowii resulted in the identification of two new esters of glucose with 3-nitropropanoic acid and acrylic acid -- kirilowin C (1) and kirilowin D (2), together with four new glucose 3-nitropropanoates - kirilowins E-H (3-6). Their structures were identified by spectroscopic data. (C) 2008 Elsevier B.V. All rights reserved.
