The progenitors of damascenone (1), the most intensive C13-norisoprenoid volatile aroma constituent of rose essential oil, were surveyed in the flowers of Rosa damascena Mill. Besides 9-O-beta-D-glucopyranosyl-3-hydroxy-7,8-didehydro-beta-ionol (4b), a stable progenitor already isolated from the residual water after steam distillation of flowers of R. damascena Mill., two labile progenitors were identified
在玫瑰蔷薇的花朵中调查了玫瑰香精油中最强的C13-去甲肾上腺素类挥发性香气成分大马香酮(1)的祖先。除了9-O-β-D-吡喃葡糖基-3-羟基-7,8-二氢-β-紫罗兰醇(4b)外,一种稳定的祖细胞已经通过蒸煮R. damascena Mill。的花朵而从残留的水中分离出,两个根据它们的合成,不稳定的祖细胞被鉴定为(3S,9R)-和(3S,9S)-megastigma-6,7-dien-3,5,9-三醇9-O-β-D-吡喃葡萄糖苷(2b)和HPLC-MS分析数据。在酸性条件下加热时,化合物2b得到大马cen酮(1),3-羟基-β-大马康酮(3)和4b。
