描述 | 2-Hydroxy-3-methylbutanoic acid is a close structure analogue of GHB (gamma-hydroxybutyrate), which is a naturally occurring neurotransmitter and a psychoactive drug[1]. A method for the quantitative determination of 2-hydroxy-3-methylbutanoic (2OH3MB) has been optimized, validated and applied to a set of wines and other alcoholic beverages. Concentrations ranged from the method detection limits to 519 μg/L for 2OH3MB, which may have relevant sensory effects. 2OH3MB was not found in distillates but was present in beer. 2OH2MB, 3OH3MB and 3OHB were found in unfermented grape derivatives[2]. |

溶解方案 |
DMSO: 105 mg/mL(888.84 mM),配合低频超声助溶,注意:DMSO长时间开封后,会吸水并导致溶解能力下降,请避免使用长期开封的DMSO 以下溶解方案都请先按照体外实验的方式配制澄清的储备液,再依次添加助溶剂: ——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议现用现配,当天使用; 以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶
