摘要
胡桃醌(5-羟基-1,4-萘醌)是从核桃楸中提取分离出来的一种萘醌类活性物质。研究采用超声波辅助浸提和减压蒸馏等方法,从核桃楸树皮中提取制得胡桃醌产品,产品得率0.09%。分别用FT-IR表征了产品的有机官能团、用GC-MS分析了产品的化学组成和产品中胡桃醌的相对含量(GC含量达96.42%)、通过1HNMR确认了产品的胡桃醌结构。本研究提供了一种从核桃楸树皮中简便快捷地提取制得高纯度的胡桃醌产品的方法。
Juglone （5-hydroxy-1, 4-naphthaoquinone） is one of the active substances that was extracted from Juglans mandshurica Maxim. Juglone product was obtained from bark of J, mandshurica by ultrasonic extraction and vacuum distillation, and the yield of product was 0, 09 %. The product was characterized by FT-IR, GC-MS and 1^H NMR. The result showed all the characteristic absorption peaks of hydroxyl-naphthaoquinone in the FT-IR spectrum of the product, The constituents of the product were determined by GC-MS to be ： 1,4-naphthaoquinone, 5-hydroxy-1,4-naphthaoquinone and 7-methoxy-1-tetralone, and the content of juglone in the product was 96, 42 %, The structure of juglone in the product was confirmed by 1^H NMR, This study offered a simple and effective method to get high purity juglone from bark of J. mandshurica.
