近日,，國際著名雜志International Journal of Cosmetic Science刊登了國外研究人員的最新研究成果“Population genetic segmentation of MHC-correlated perfume preferences,。”,，文章中,，作者揭示了女性對香水味道喜好是受基因調控的；香水是每個女人最愛的產(chǎn)品,，瑞士一項研究發(fā)現(xiàn),，女性對于香水味道的喜好，都會受到一組名為MHC的基因調控,，該基因也決定了每個人會受到哪一種異性的氣味所吸引,。
據(jù)報道，瑞士聯(lián)邦技術研究所日前對116名受訪者進行了不同氣味的測試,，包括肉桂,、玫瑰、雪松等10種物質,，而每次的測試濃度與環(huán)境都不相同,。
結果發(fā)現(xiàn)，最受歡迎的氣味是“香樹脂”,，而“香根草”因為氣味較平淡,，最不受歡迎。研究指出,，在不同氣味的刺激下,，人類受基因MHC控制會對味道呈現(xiàn)出強度不同的反應。
英國劍橋大學專家萊斯利納普表示,，同一款香水給不同的人使用,，會產(chǎn)生不一樣的反應，而MHC基因將來也會被擴大研究,。另一名瑞士專家德金德也表示,，MHC基因與異性氣味的關系是在女性聞嗅男性襯衫味道的實驗中發(fā)現(xiàn)的，他還指出,，90年代初期就曾發(fā)現(xiàn)過人體對于氣味的喜好與免疫基因有關,。（生物谷Bioon.com）

Population genetic segmentation of MHC-correlated perfume preferences

Keywords: individual preferences;major histocompatibility complex;mate choice behaviour;olfaction;perfume ingredients;perfumes;scent;sexual communication Synopsis It has become difficult to find a matching perfume. An overwhelming number of 300 new perfumes launch each year, and marketing campaigns target pre-defined groups based on gender, age or income rather than on individual preferences. Recent evidence for a genetic basis of perfume preferences, however, could be the starting point for a novel population genetic approach to better match perfumes with people’s preferences. With a total of 116 participants genotyped for alleles of three loci of the major histocompatibility complex (MHC), the aim of this study was to test whether common MHC alleles could be used as genetic markers to segment a given population into preference types. Significant deviations from random expectations for a set of 10 common perfume ingredients indicate how such segmentation could be achieved. In addition, preference patterns of participants confronted with images that contained a sexual communication context significantly differed in their ratings for some of the scents compared with participants confronted with images of perfume bottles. This strongly supports the assumption that genetically correlated perfume preferences evolved in the context of sexual communication. The results are discussed in the light of perfume customization.
