Rapid determination of vitamin E in vegetable oils by reversed-phase high-performance liquid chromatography.
A quick and direct method for measuring tocopherols (alpha, beta+gamma and delta) in vegetable oils has been developed using RP-HPLC with UV detection. Previous extraction of tocopherols is not required. The oil is diluted in hexane and an aliquot is mixed with ethanol containing an internal standard (alpha-tocopherol acetate). The chromatographic system consists of an ODS-2 column with a metha...
متن کاملReverse phase analytical and preparative high pressure liquid chromatography of aflatoxins.
Reverse phase high pressure liquid chroma· k)graphy (HPLC) was investigated and found applicahle for determining 6 aflatoxins. Afla. toxins Mz• Mt• Gz• Gt , and Bt were completely resolved and Bz was satisfactorily separated on aCtS (10 ,urn. 4 mm id X 30 em) column with an eluting solvent of acetonitrile.water (35+ 65) and flow rate of 1.5 ml/min. Compounds were detected by ultraviolet absorba...
متن کاملThe Combination Process for Preparative Separation and Purification of Paclitaxel and 10-Deacetylbaccatin III Using Diaion® Hp-20 Followed by Hydrophilic Interaction Based Solid Phase Extraction
There is no other naturally occurring defense agent against cancer that has a stronger effectthan paclitaxel, commonly known under the brand name of Taxol®. The major drawback for themore widespread use of paclitaxel and its precious precursor, 10-deacetylbaccatin III (10-DABIII), is that they require large-scale extraction from different parts of yew trees (Taxus species),cell cultures, taxane...
متن کاملPurification of saponins from leaves of Panax notoginseng using preparative two-dimensional reversed-phase liquid chromatography/hydrophilic interaction chromatography.
Saponins are widely distributed in the plant kingdom and have been shown to be active components of many medicinal herbs. In this study, a two-dimensional purification method based on reversed-phase liquid chromatography coupled with hydrophilic interaction liquid chromatography was successfully applied to purify saponins from leaves of Panax notoginseng. Nine saponin reference standards were u...
