A rapid and sensitive ultra high performance liquid chromatography coupled to triple quadrupole tandem mass spectrometry method was established and employed to determine 21 nucleosides, nucleobases, and amino acids in 60 samples from different parts of Angelicae Sinensis Radix. The established methods were validated by good linearity (r2 > 0.9937), limits of detection (0.12–77.75 ng/mL), limits...
A rapid HPLC method has been developed for the simultaneous determination of 23 amino acids, 10 biogenic amines and the ammonium ion in wine. Samples were pre-column derivatised with diethyl ethoxymethylenemalonate and separated using reversed-phase HPLC within 30min. The matrix effect was evaluated when measuring samples taken from different stages of fermentation. Most compounds showed no obvious...
Lipoprotein lipase (LPL) of Tianfu meat goose was cloned and sequenced using a RT-PCR approach. The nucleotide sequence covered 468 bp with an open reading frame of 155 amino acids. Alignment analysis indicated that the nucleotide sequences are highly conserved to other species studied including chicken, domestic guinea pig, house mouse, Norway rat, cattle, cow and goat, and the homologies are 92...
