“…These include rotenoid derivatives (Chibber and Khera, 1979;Svasti et al, 1999), and other isoflavone derivatives (Mathias et al, 1998;Rajasekhara Rao and Srinivasa Rao, 1991;Sharma et al, 1980;Farag et al, 1999). These compounds include both O-linked and C-linked glycosides, simple glucosides and oligosaccharide glycosides.…”

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.

“…(Leguminosae) has been extensively investigated for its isoflavonoid and neoflavonoid constituents (Ahluwalia, Sachdev, & Seshadri, 1965;Ahluwalia & Seshadri, 1963;Banerji, Murti, & Seshadri, 1965, 1966Banerji, Murti, Seshadri, & Thakur, 1963;Dhingra, Seshadri, & Mukerjee, 1974;Farag, Ahmed, Terashima, Takaya, & Niwa, 2001;Mukerjee, Saroja, & Seshadri, 1971;Ramakrishna et al, 2001;Sharma, Chibber, & Chawla, 1979a, 1979b, 1980a, 1980b. To the best of our knowledge, no phytochemical work on the root bark of this species has been reported.…”
