摘要：

A crude enzyme was extracted from fresh tea leaves and it showed β-glucosidase activity, using p-nitrophenyl-β-, d,-glucoside as a substrate. The non-volatile fraction of a hot-water extract from green tea was incubated with the crude enzyme extract at 37°C for 30 min. After this enzymatic hydrolysis, the formation of (Z)-3-hexenol, linalool oxide I, linalool, methyl salicylate, geraniol, benzyl alcohol and 2-phenylethanol was observed. Geranyl-β-, d,-glucoside was synthesized by the Koenigs–Knorr reaction. When it was reacted with the crude enzyme extract of tea leaves, geraniol was identified on GC as an enzymatic hydrolysis product. Thus, geranyl-β-, d,-glucoside seems to be the precursor of geraniol in tea leaves. © 1990 by the Japan Society for Bioscience, Biotechnology, and Agrochemistry. All rights reserved.
