Abstract

The cyanoglycoside, prunasin, was isolated for the first time as an aroma precursor of benzaldehyde from fresh tea leaves (Camellia sinensis var. sinensis cv. Yabukita). Prunasin was readily hydrolyzed by a crude enzyme prepared from the fresh tea leaves to liberate benzaldehyde. The isomerization of prunasin under neutral conditions was also recognized.

摘要

氰基糖苷苦杏仁苷首次从新鲜茶叶（茶树品种龙井43）中分离出来，作为苯甲醛的香气前体。苦杏仁苷很容易被从新鲜茶叶中制备的粗酶水解，从而释放出苯甲醛。苦杏仁苷在中性条件下的异构化也得到了确认。
