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.
