herbaceous note.

a sweet, honey-like intense odor that characterizes all other derivatives

Essential oil composition
In addition to triterpene and spartitrioside (the constituents of the flowers), five flavonoid glycosides bearing
a catechol structure in ring B were isolated from the butanol extract, and their structures were elucidated as isoquercitrin (quercetin
3-beta-glucoside), luteolin 4?-beta-glucoside, quercetin 3, 4?-diglucoside, azaleatin 3-beta-glucoside (quercetin 5-methylether
3-beta-glucoside) and quercetin 4?-beta-glucoside.
Taste threshold values
Taste characteristics at 30 ppm: sweet, hay, warm, herbal tea with a woody, herbal nuance.
