Abstract

Geraniol dehydrogenase, the specific enzyme involved in geraniol to citral trans (geranial) transformation, activity was monitored in various lemongrass cultivars differing in amounts and relative percentages of citral and geraniol in their essential oils. The enzyme activity had a positive and significant association with citral to geraniol, and geranial to geraniol ratios. The results are suggestive of a strong relationship between the enzyme activity and essential oil quality in lemongrass cultivars.

Key words

Lemongrass (Cymbopogonflexuosus Stapf.) - cultivars - geraniol dehydrogenase - essential oil quality - biochemical screening - citral
