The concentration from the metabolites was established by triple quadrupole mass spectrometer outfitted that has a pump and an autosampler. Chroma tography separation was carried out with Agilent ZORBAS SB C18 column. A mobile phase consisting of acetonitrile, methanol was implemented, using the movement rate set at 0. 3 ml min1 in addition to a five min run time. A number of reactions monitoring mode was utilized for your quantification as well as the selected transitions of m/z had been 401110 for coniferin, 359329 for lariciresinol, 361164 for secoisolariciresinol, 357164 for mataireisnol, 357 151 for pinoresinol, 179146 for coniferyl alcohol, 685523 for secoisolariciresinol diglucoside, 286 117 for kaempferol, 302 151 for quer cetin, and 316 299 for isorhamnetin. Standards of laricir esinol, and pinoresinol have been prepared in our laboratory, other specifications have been obtained from Sigma Aldrich.
Q TOF LC/MS analysis of flavonoids Roots and leaves were harvested from plantlets of I. indigotica. Samples had been dried at 40 C to consistent fat and powdered for extraction. A powdered selleck chemicals sample was extracted in solvent by reflux extraction process at 80 C 3 times, and concentrated to 50 mL. Chemical analysis was performed working with an ultra performance liquid chromatography method fitted with an Agilent 6538 UHD Precise Mass Q TOF LC/MS outfitted with an ESI interface. The chromatographic separation of compounds was achieved making use of an Agilent Eclipse Plus C18 column in binary gradient mode at a flow fee of 0. 3 mL/min. Column oven and car sampler temperatures have been maintained at 40 C and four C, respectively.
The column temperature was held at 25 C as well as the sample injection volume was 5 uL. The full scan mass spectra had been measured in a scan range from 100 to one,500 amu by using a scan resolution of 13,000 m/z/s. Spectra have been acquired inside the favourable and adverse ionization modes. Information examination was performed employing the Agilent Mass Hunter Workstation program. the original source The target compounds had been recognized by the item ion spectrum, from the beneficial and damaging ion modes. The extracted fragment mass ions of your target compounds have been as follows, kaempferol, m/z 287. 055, 285. 041. quercetin, m/z 303. 049, 301. 036. kaempferol 3 O glucoside, m/z 449. 108, 447. 0963. quercetin three O rhamnoside 7 O rhamnoside, m/z 595. 166, 593. 154. kaempferol three O rhamnoside seven O glu coside, m/z 595. 166, 593. 154. quercetin three O glucoside seven O rhamnoside, m/z 611.
16, 609. 148. quercetin 3 O rhamno side 7 O glucoside, m/z 611. 16, 609. 148. Co expression analysis Co expression analyses were carried out utilizing a co expression Gene Search algorithm to the RIKEN PRIMe internet site. A total of 71 Arabidopsis genes using the highest homology to I. indigotica UGTs were collected as query genes. The co expression relationships of your genes exhibited correlation coefficients 0.
