| characteristics | violet oil can be extracted from the flowers of Violet, a plant of Viola family, with petroleum ether extraction. the freezing point is 50 ℃ and the acid value is 47.7. After leaching, net oil, relative density 0.9539, freezing point 15 ℃, refractive index 1.4932,[α]D 5. |
| violet flower net oil | a precious natural plant spice. Mainly produced in England and France. The extract can be obtained from the flowers of Violet from the Viola family by petroleum ether extraction, the freezing point is 50 ℃, and the acid value is 47.7. After leaching, net oil, relative density 0.9539, freezing point 15 ℃, refractive index 1.4932,[α]D 5. The extract has a quiet and clear fragrance of green beans, which is quite like acacia, iris, and woody. The main components of the clean oil are true ionone, eugenol, benzyl alcohol, methyl salicylate, nondienol, nondienal, hexanol, hexenol, heptenol, etc. Mainly used to prepare high-grade perfume essence. Due to the scarcity and price, production is basically stopped and replaced by violet leaf oil. Artificial can be ionone, methyl ionone as the base fragrance, violet leaf oil or methyl heptyne carboxylate to increase the clear gas, with jasmine, acacia, ylang oil compared to the flower fragrance, and then anisaldehyde, jasmine aldehyde to add bean flavor. |
| violet | alias grass violet, grass osmanthus. A perennial herb of the genus Cruciferae, often cultivated in one or two years. Chromosome number 2n = 2x = 14. Violets have a long history of cultivation and have been cultivated as herbs in ancient Greece. In 1542, there were three colors of red, purple and white. In 1568, there was a record of double-petal varieties for the first time. Before 1900, double-petal varieties with a double-petal rate of more than 50% had been selected. After the 20th century, the study of violets from cytogenetics explained the cytological basis for the production of double valve lines. And made extremely effective variety improvement work. morphological characteristics plant height 20 ~ 60cm, the whole plant is covered with gray stellate pilose. Stems erect, base slightly lignified. Leaves alternate, oblong to oblanceolate, entire, gray-green. terminal racemes, aromatic; sepals 4, the base of the sepals on both sides is saccate; petals 4, obovate, cruciform, flower diameter about 3cm. Flowering period in spring, silieres are cylindrical, the seeds have white membranous wings, the 1000-grain weight is about 1.7g, the germination rate is about 50%, and the seed life is 4 years. varieties, types, varieties and horticultural varieties are: ① summer violet, also known as var.annua. Annual, small stems and leaves, early flowering, growth period of 100~150 days, strong aroma, mostly used for cut flowers. Spring sowing, flowering from June to August. Winter greenhouse cultivation, Christmas can bloom. (2) autumn violet (var. au-tumnalis). Sowing in early spring and flowering in autumn. Sowing in autumn and cultivated in greenhouse can bloom continuously from winter to spring. (3) winter violet (var. hiber-na). Winter flowering, height 50 ~ 60cm, autumn sowing, flowering from winter to summer. It can be cultivated in the open field in southern China, with larger plants. |
| production method | violet (Viola odorata L.) dry leaves are used as raw materials and extracted by petroleum ether extraction, with a yield of 0.009~0.12%. |
