Two new isoflavone 7-O-α-4″-anhydro-4″,5″-didehydroglucuronides from Streptomyces sp. LZ35ΔgdmAI.Nat Prod Res. 2016; 30(2):180-4.NP
Two isoflavone 7-O-α-4″-anhydro-4″,5″-didehydroglucuronides, namely daidzein 7-O-α-4″-anhydro-4″,5″-didehydroglucuronide (1) and genistein 7-O-α-4″-anhydro-4″,5″-didehydroglucuronide (2), were isolated and identified from the mutant strain of Streptomyces sp. LZ35ΔgdmAI. Their structures were elucidated by the analysis of their high resolution mass spectrometry (HR-MS) and 1D, 2D Nuclear magnetic Resonance (NMR) spectroscopic data. They are new natural products and maybe the transformed products of the soybean meal by Streptomyces sp. LZ35ΔgdmAI.
