isopropanol/potato

Carbaryl (1-naphthyl-N-methylcarbamate) was extracted from corn and potato with acetone. The acetone extract was partitioned into methylene chloride-hexane and concentrated for cleanup on a 5% water-deactivated Florisil column. The fraction containing the carbamate was subjected to high pressure

"Tocosh" is a potato that has undergone a process of hydraulic oxidation that enhances its antimicrobial properties so that this natural resource can be used in medical sciences. The aim of this study was to develop and evaluate the antibacterial and cytotoxic

The existence of three infectious forms of potato spindle tuber viroid (PSTV) RNA from Scopolia sinensis was demonstrated by fractionation with high salt, by reverse phase and high pressure liquid chromatography, and by polyacrylamide gel electrophoresis. Purification of fraction II was achieved by

One hundred eighty-two authentic potato samples ( Solanum tuberosum) of known variety were collected from various German regions in 2016 and 2017. Samples were extracted with a liquid-liquid-extraction protocol that included isopropanol, methanol, and water in order to focus on lipophilic

A reverse transcription polymerase chain reaction (RT-PCR) protocol was developed using two 20-mer primers located in nuclear inclusion genes NIa and NIb of potato virus Y (PVY). A 1017 bp PCR-product was detected in dormant potato tubers, infected with PVY(O), but not in tubers from healthy plants.

A simple and efficient method is presented for the extraction, cleanup, and liquid chromatographic (LC) determination of linuron and 3 of its metabolites, 3-(3,4-dichlorophenyl)-1-methyl urea (DCPMU), 3-(3,4-dichlorophenyl) urea (DCPU), and 3,4-dichloroaniline (DCA), in potatoes. Samples are

In 2010 and 2011, diseased watermelon plants (Citrillus lanatus [Thunb.] Matsun and Nakai) had chlorotic and wilted leaves and vines prior to harvest in three out of four sampled commercial fields in the Municipality of Matamoros, State of Coahuila, in the north-central region of Mexico known as La
