摘要：

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.
