Explain the role of surface sterilising chemicals in aseptic culture initiation and function of sucrose in MS medium?Apple puree was analyzed for petulin by HPLC-MS-MS after SPE clean-up. The procedure was 10.0g of puree + 10μl of a 10μg/ml solution of isotopically labeled petulin as internal standard were treated with 10.0ml of pectinase and acetic acid, centrifuged, and filtered. Four ml of the filtrate was passed through a SPE cartridge. The petulin was eluted with 2.0ml of ethyl acetate. The sample was evaporated to dryness and the residue dissolved in 1.0ml of the mobile phase. The analyte signal was 127 and the internal standard 197.
