Dual high-resolution alpha-glucosidase and radical scavenging profiling combined with HPLC-HRMS-SPE-NMR for identification of minor and major constituents directly from the crude extract of Pueraria lobata.[Pubmed:25679337]
J Nat Prod. 2015 Feb 27;78(2):294-300.
The crude methanol extract of Pueraria lobata was investigated by dual high-resolution alpha-glucosidase inhibition and radical scavenging profiling combined with hyphenated HPLC-HRMS-SPE-NMR. Direct analysis of the crude extract without preceding purification was facilitated by combining chromatograms from two analytical-scale HPLC separations of 120 and 600 mug on-column, respectively. High-resolution alpha-glucosidase and radical scavenging profiles were obtained after microfractionation of the eluate in 96-well microplates. This allowed full bioactivity profiling of individual peaks in the HPLC chromatogram of the crude methanol extract. Subsequent HPLC-HRMS-SPE-NMR analysis allowed identification of 21 known compounds in addition to two new compounds, i.e., 3'-methoxydaidzein 8-C-[alpha-D-apiofuranosyl-(1-->6)]-beta-D-glucopyranoside and 6''-O-malonyl-3'-methoxydaidzin, as well as an unstable compound tentatively identified as 3'-de-O-methylpuerariafuran.
[Isoflavones from vines of Pueraria lobata].[Pubmed:20353004]
Zhongguo Zhong Yao Za Zhi. 2009 Dec;34(24):3217-20.
OBJECTIVE: To investigate the isoflavones from the vines of Pueraria lobata. METHOD: The compounds were isolated by column chromatography over silica gel and RP-C18, and purified by Sephadex LH-20 column chromatography and preparative TLC. The structures were elucidated on the basis of physico-chemical properties and spectral data. RESULT: Twelve compounds were isolated and identified as: 3'-methoxydaidzein (1), formononetin (2), genistein (3), daidzein (4), daidzin (5), genistin (6), ononin (7), 5-hydroxyl ononin (8), calycosin (9), 6"-O-acetyl genistein (10), 6"-O-acetyl daidzin (11), puerarin (12). CONCLUSION: For the first time, compounds 9-11 were isolated from the genus Pueraria plant, and compounds 1, 3, 6-8 were obtained from the vines of this plant.
Identification of isoflavones in the roots of Pueraria lobata.[Pubmed:17253303]
Planta Med. 1998 Oct;64(7):620-7.
The isoflavones of the roots of Pueraria lobata (Willd.) Ohwi (Puerariae Radix) were investigated by high-performance liquid chromatography (HPLC) coupled to photodiode array (PDA) and to mass spectroscopy (MS) using atmospheric pressure chemical ionization (APCI) or electrospray ionization (ESI) in combination with collision-activated decomposition (CAD) (HPLC-APCI-CAD-MS or ESI-CAD-MS) for identification of glycosides and HPLC-APCI-CAD-MS for identification of aglycones. The major glycosides are derived from daidzein ( 9) and most are 8- C-glycosides. 3'-Hydroxypuerarin-4'- O-deoxyhexoside ( 2B) and 3'-methoxy-6''- O- D-xylosylpuerarin ( 6) were identified as new constituents. MS data were obtained for puerarin-4'- O- D-glucoside ( 1), 3'-hydroxypuerarin ( 2A), puerarin ( 3), 3'-methoxypuerarin ( 4), 6''- O- D-xylosylpuerarin ( 5), daidzin ( 7) and 3'-methoxydaidzin ( 8), which were previously characterized by NMR analysis. Isoflavones identified in Puerariae Radix comprise 3'-methoxydaidzein ( 10), genistein ( 12), daidzein-7- O-methyl ether ( 13A), 3'-methoxydaidzein-7- O-methyl ether or 3'-methoxyformononetin ( 13B) and biochanin A ( 15), while previous characterization of daidzein ( 9) and formononetin ( 14) was substantiated by MS data. The structure of compound 11 could not be established by MS techniques. The estrogenic activity was mainly located in the aglycone fraction.
Activity-guided isolation of constituents of Tephrosia purpurea with the potential to induce the phase II enzyme, quinone reductase.[Pubmed:9322358]
J Nat Prod. 1997 Sep;60(9):869-73.
An isoflavone, 7,4'-dihydroxy-3',5'-dimethoxyisoflavone (1), and a chalcone, (+)-tephropurpurin (2), both novel compounds, as well as six constituents of known structure, (+)-purpurin (3), pongamol (4), lanceolatin B (5), (-)-maackiain (6), (-)-3-hydroxy-4-methoxy-8,9-methylene-dioxypterocarpan (7), and (-)-medicarpin (8), were obtained as active compounds from Tephrosia purpurea, using a bioassay based on the induction of quinone reductase (QR) activity with cultured Hepa 1c1c7 mouse hepatoma cells. Additionally, three inactive compounds of known structure, 3'-methoxydaidzein, desmoxyphyllin B, and 3,9-dihydroxy-8-methoxycoumestan, were isolated and identified. The structure elucidation of compounds 1 and 2 was carried out by spectral data interpretation.
