Comparison of terpene components from flowers of Artemisia annua
Bangladesh Journal of Pharmacology, 2012 Terpene constituents of essential oils obtained by steam distillation from Artemisia annua flowers at the pre-, full- and post-flowering stage was investigated by gas chromatography (GC) and gas chromatography-mass spectrometric detector (GC-MS). The aim

Metabolism of Monoterpenes [PDF]
Plant Physiology, 1985 l-Menthone of peppermint leaves is reduced to d-neomenthol which is glucosylated and transported to the rhizome, whereupon the beta-d-glucoside is hydrolyzed, the aglycone oxidized back to l-menthone, and this ketone converted to l-3,4-menthone lactone.
