Allium schoenoprasum L. - Amaryllidaceae - chives, **Schnittlauch**

Herbaceous perennial plant, 10-50cm tall, native to Europe, Asia and North America.

"In culinary use, the scapes and the unopened, immature flower buds are diced and used as an ingredient for fish, potatoes, soups, and other dishes." [[https://en.wikipedia.org/wiki/Chives]]

"Two kinds of disulfide has been isolated from Allium schoenoprasum and their structures established as methyl pentyl disulfide and pentyl hydrodisulfide by spectroscopic and synthetic methods. These compounds, which smell like sweet onions, are important aroma constituents." \\

"Using well-established techniques, a sample was obtained of the steam volatile oil of chive (Allium schoenoprasum L.). A total of 30 components were identified and the neutral oil contained mainly sulfur compounds (16.8%). The most important constituents are dipropyl disulfide, methyl pentyl disulfide, pentyl hydrodisulfide and (cis and trans) 3,5-diethyl-1,2,4-trithiolane." \\
