Abstract

The invention discloses an isoflavone compound extracted from rose waste residues, a preparation method of the isoflavone compound and an application of the isoflavone compound. The compound is namedas 4'-hydroxy-7-(3-hydroxypropanoyl)-6-methoxy-isoflavone, the molecular formula of the compound is C19H16O6, and the structural formula of the compound is as shown in the specification. Damask rose waste residues after rose essential oil production serve as raw materials and are subjected to extraction, organic solvent extraction, MCI discoloration, silica-gel column chromatography and high-performance liquid chromatographic separation to prepare the compound. The compound is added into a cigarette filter, can coordinate with tobacco fragrance, reduces cigarette smoking irritation, has obvious fluid promoting and smoke aftertaste functions and has an obvious smoke softening effect.

Description

technical field [0001] The invention belongs to the technical field of phytochemistry, and in particular relates to an isoflavone compound extracted for the first time from waste residue of Damask rose after essential oil production, which can improve the smoking quality of cigarettes. At the same time, the invention also relates to the preparation method of the compound and the application of the compound in cigarette production. Background technique [0002] Damascus rose (scientific name Rosa Damascena, common name Damask rose), also known as Turkic rose, Rosaceae Rosa, is a classical garden rose, bushy shrubs, native to Syria, widely planted in France since the 14th century, Damascus rose is also a Bulgarian rose The main rose variety planted has double-petaled flowers, the petals are slightly lighter in color, and has a satin-like texture; the pure and delicate floral fragrance makes it crown the top-grade oil roses, so it is widely planted for extraction rose essentia...
