HPLC of Formula: 91523-50-1. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 6-Hydroxy-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid, is researched, Molecular C10H11NO3, CAS is 91523-50-1, about Gas chromatography mass spectrometry analysis and in vitro antibacterial activity of essential oil from Trigonella foenum-graecum.

Objective: To evaluate the antibacterial activity of essential oil from Trigonella foenum-graecum seeds powder, and identify the compounds from the extracted oil. Methods: The seeds powder of Trigonella foenum-graecum was subjected to Clevenger extractor. Seven strains of bacteria were used to test antibacterial activity of the extract The activity against bacteria was tested by disk diffusion method using Whatman Number1 filter paper. Gas chromatog. mass spectrometry anal. was performed with an Agilent7890/5975B-gas chromatog./mass selective detector. Results: The hydrodistillation of seeds powder yielded 0.285% (v/w) of oil. Disk diffusion of the oil showed bactericidal activity against both Gram neg. and Gram pos. bacteria of lasted strains. The inhibition zone ranged from (8 ± 0) mm to (15.0 ± 0.7) mm depending on microbial strains. Gas chromatog. mass spectrometry anal. showed 14 different compounds The total compounds represented 80.96% of the oil. Conclusions: The antibacterial activity is due to the effects of different biol. active compounds present in the extract Identification of the compounds may help to develop new effective antimicrobial agent(s). Further researches on purification, characterization and toxicol. of the active compounds are needed.
This literature about this compound(91523-50-1)HPLC of Formula: 91523-50-1has given us a lot of inspiration, and I hope that the research on this compound(6-Hydroxy-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid) can be further advanced. Maybe we can get more compounds in a similar way.
