Abstract
The composition of volatile constituents from tissues of Korean wild garlic, Allium victorialis var. platyphyllum collected from different habitats of Ulleung Island, Korea, was determined. The concentrations of total volatile constituents in garlic bulbs and stems were variable. The most abundant volatile compound in A. victorialis bulb extract was alanine (47–65%), followed by dimethyl tridisulfide (5.1–10.3%) and allyl disulfide (0.1–12.1%). Dimethyl trisulfide (5.2–10.3%), diallyl disulfide (0.1–12.1%) and dimethl pentasulfide (0–0.3%) were abundant in stem tissues. Very significant differences in the composition of volatile sulfides in stems and bulbs of A. victorialis were noticed. Finally principal component analysis (PCA) was adopted to know the chemical-population structure of the garlic extracts. Habitat of garlic plant appreciably affected the proportions of alk(en)yl group (methyl, m-propyl and allyl radicals) in the of bulb and stem tissues.
