Цікавий факт
Guilin, whose name translates to Forest of Sweet Osmanthus, has around 12 million sweet-scented osmanthus trees covering more than 80 varieties. Around 200,000 of those trees are planted in downtown Guilin. The Chinese idiom "pluck osmanthus in the Toad Palace" was a refined way of saying "passing the exam".
Отримання й хімія
Спосіб отримання
Petroleum ether extraction of the flowers gives a concrete, and alcohol extraction of the concrete gives the absolute. The yield of absolute is only about one kilo per 3,000 kilos of flowers, and the enfleurage method or the infusion process have also been applied to these flowers. The trees flower from September to mid-November. The flowers are harvested manually by beating the branches with long sticks so that they fall onto a large sheet spread on the ground. Fresh flowers wither very quickly, so they are preserved in brine for a few weeks to develop the olfactory precursors. After salting, the notes are stronger and more stable, with ripe fruit, lactonic and sweet floral notes. The flowers are then washed with water to remove salts and impurities and extracted with a volatile solvent into concrete. Storage of the concrete is the final stage of the aging process, during which the tea notes are developed. The concrete is washed with ethanol to remove the waxes and concentrate the olfactory components, which gives the absolute. The blossoms are extracted at local distilleries during the autumn and winter.

У парфумерії
In fine perfumery and personal care products, osmanthus absolute enhances fruity top notes and lends roundness to a composition. It combines well with woody, spicy, floral and tobacco accords. It is used in the heart of floral accords to add a sensual note. It is used in reconstitutions of yellow fruits, tobacco or syrupy accords to give them a fruity and floral note. In flavours it is useful for creating yellow fruit flavors. A less coloured grade has an enhanced fruity apricot-jam character. The perfumed oil left by enfleurage or infusion can be used as it is in cosmetic preparations. As a flavour at 10 ppm the absolute tastes sweet, fruity, berry-like, jammy, herbal and fresh. Osmanthus does not feature in the current PREMIEREPEAU collection.
