Pressurized liquid extraction (PLE) has been used for the extraction of beta-sitosterol from food samples. In the present work, extractions were performed by mixing ground samples with Hydromatrix(More)
This paper reports the development of an analytical method for the determination of isoflavones in legumes using LC-MS/MS. A modified approach of the QuEChERS methodology was used to extract the(More)
Pressurized liquid extraction (PLE) was used to isolate tocopherols from seeds and nuts. Very clean extracts were obtained, which were injected directly into the chromatographic system. This enables(More)
