Safety Profile
USE WITH AWARENESSWhat Does Wisteria sinensis, microwave extraction Smell Like?
The scent unfolds like a spring morning – initial bursts of grape-like sweetness give way to a heart of true floral character with hints of lilac and orange blossom. There’s an underlying green freshness that prevents cloying sweetness, evolving into a delicate honeyed dry-down. The microwave extraction method preserves volatile top notes that are often lost in traditional extraction, resulting in an unusually vibrant floralcy with subtle almond-like nuances in the base.
In Famous Fragrances

Chemistry, Properties & Perfumer Guide
The Chemistry
Wisteria sinensis extract contains a complex mixture of volatile organic compounds including linalool, benzyl alcohol, and methyl anthranilate. The microwave-assisted extraction process enhances yield of oxygenated monoterpenes while minimizing thermal degradation. Key aroma compounds include wisterin, a unique glycoside that hydrolyzes during extraction to release aromatic aglycones. The extraction method preserves delicate esters that contribute to the fresh top notes.
