- | Constituents of the absolute of B.megastigma from Tasmania were β-ionone and many of its derivatives like 7,8-dihydro—β-ionone, 7,8-dihydro—β—ionol, 4-oxo-β—ionone, 4-hydroxy-β—ionone, 4-oxo-β—ionol, and 3-hydroxy-β-ionone as well as isomeric 3-hydroxymegastigm-7-en-9-ones and megastigm-7-ene-3, | + | " |

+ | "For flavor and fragrance use, the flowers of Boronia megastigma are collected, extracted with petroleum ether (a hydrocarbon fraction), concentrated into a waxy concentrate (a concrete) and then the concrete is re-extracted with alcohol, and concentrated to form Boronia absolute. The absolute is typically a dark green semi-fluid liquid that possesses a fruity, tea-like, slightly herbaceous odor. In perfumes, boronia is used in violet, mimosa and honeysuckle bases, while for flavors it adds body and naturalness to flavors such as raspberry, strawberry, peach, etc." \\ | ||

+ | "The petal waxes clearly contribute the bulk of the weight of the concrete from Boronia flowers, and the C17 to C33 saturated branched and linear hydrocarbons represent the proportion of these waxes amenable to GC analysis." | ||
+ | Volatiles of the fraction to C20 (representing 16.0-25.9% of the concrete) were mainly α-pinene (2.3-11.0%), | ||

+ | "While aroma constituents formed from carotenoids are perhaps the most important to the aroma of boronia, the absolute also contains a number of linalool related materials (linalool, linalyl acetate and a series of 8-hydroxylinalool esters) and compounds in the methyl jasmonate series... that undoubtedly impact the odor profile substantially." | ||
