Gas-Liquid Chromatography of Trimethylsilyl Derivatives of Abscisic Acid and Other Plant Hormones1-
A bstract. This paper describes a new method for qualitative and quantitative assay of abscisic acid and other acidic plant hormones, such as indoleacetic acid and the gibberellins, by the gas-liquid chromatography of their trimethylsilyl derivatives. Interfering substances in plant extracts were largely removed by preliminary oolumn chromatography with carbon-celite and elution of the absoisic...

متن کاملGas-liquid chromatography of bile acids: a new liquid phase for both acetate and trimethylsilyl derivatives.
Polymetaphenoxylene (PPE-20) has been found to be more useful than cyclohexane dimethanol succinate (HI-EFF-8-BP) for trimethylsilyl derivatives of bile acids and to be preferable to trifluoropropyl substituted silicone (OV-210, QF-1) for analysis of their acetate derivatives.
متن کاملMass spectrometry of alditols as trimethylsilyl derivatives
The trimethylsilyl ethers of alditols with 3, 4, 5 and 6 carbon atoms were investigated. The mass spectra are unusually clearly correlated with the structures. The predominant fragmentations are cleavages in the carbon chain and rearrangement loss of trimethylsilanol. The spectra are closely related to those of the methyl ethers. A spectrum unambiguously identifies a compound as an alditol and ...
متن کاملCucurbit[5]uril-metal complex-induced room-temperature phosphorescence of α-naphthol and β-naphthol.
Similar to the larger members of the cucurbituril family, such as cucurbit[8]uril (Q[8]), the smallest member, cucurbit[5]uril (Q[5]), can also induce room-temperature phosphorescence (RTP) of α-naphthol (1) and β-naphthol (2). The relationship between the RTP intensity of 1 and 2 and the concentration of Q[5] or Q[8] suggests that the mechanism underlying the Q[5] complex-induced RTP is differ...
