The major dietary anthocyanin, cyanidin-3-glucoside, was prepared on a 4 g scale from three units of diethyl [2-13C]malonate and one unit of [1,3-13C2]acetone, such that five isotope locations were distributed throughout the molecule to provide a penta-13C5-labelled anthocyanin, [6,8,10,3â²,5â²-13C5]cyanidin-3-glucoside chloride, for use in human stable-isotope tracer studies.
主要的膳食花青素--花青素-3-葡萄糖苷是以 4 克为单位,由三个单位的[2-13C]丙二酸二乙酯和一个单位的[1,3-13C2]丙酮制备而成的、这样,在整个分子中分布了五个同位素位置,从而得到了五-13C5 标记的花青素--[6,8,10,3â²,5â²-13C5]氯化花青素-3-葡萄糖苷,用于人体稳定同位素示踪研究。
