我们最近开发了2D 1H-13 C HSQC 0方法来量化复杂混合物中的单个化学物质。HSQC 0方法已在相位循环和梯度选择版本中实施。与定量1D NMR一样,HSQC 0中的归一化积分信号强度与混合物中单个化学品的浓度成比例。我们应用HSQC 0方法选择性地定量存在于从海绵软骨藻分离的Verrucosispora sp.提取物中的1%w/w水平的噻可拉林。加勒比海我们期望这种方法可以用于定量提取物中的其他感兴趣的天然产物,而无需事先纯化。
We recently developed 2D 1H-13C HSQC0 approach to quantify individual chemicals in complex mixtures. The HSQC0 approach has been implemented in phase-cycled and gradient selective versions. As in quantitative 1D NMR, the normalized integrated signal intensities in HSQC0 are proportional to the concentrations of individual chemicals in the mixture. We applied the HSQC0 approaches to selectively quantify thiocoraline present at a level of 1% w/w in an extract from a Verrucosispora sp. isolated from the sponge Chondrilla caribensis f. caribensis. We expect that this approach can be used to quantify other natural products of interest in extracts without prior purification.
