What are the constituents of jasminum sambac linn plant?

Answer 1

KKG didn't exactly answer your question

Inspiration for Jasmin perfumes comes from the constituents identified in natural Jasmin: Benzyl Acetate, Benzyl Alcohol and cis-Jasmone give the fruity aromatic jasmin qualities, Linalool and Farnesol give the flowery character and Methyl Anthranilate and Indole give the narcotic animalic backgound. Whilst the above few materials will pass as a jasmin they do little justice to the natural absolute with its 300 plus other components.
The Sambac variety has a higher Linalool level and more green notes from the family of cis-3-Hexenol esters.

Answer 2

Jasminum Sambac is the botanical name of the flower plant Jasmine. Jasmine or Jessamine, common name applied to plants of two genera: true jasmines and false jasmines. The true jasmines are a genus of shrubs and climbing plants, including about 450 species, most of which are native to tropical regions of Eurasia. The salver-shaped jasmine flower has a five- or eight-cleft calyx, five- or eight-lobed corolla, two stamens, and a solitary pistil. The fruit is a two-lobed berry. The common white jasmine is native to southern Asia. It is a tall climbing plant, bearing pinnate leaves and fragrant white flowers. Spanish jasmine is a bushy shrub, native to Indonesia, bearing white flowers flecked with pink. Arabian jasmine is a white-flowered climbing plant, native to India. Flowers of all three species contain an essential oil used in making perfumes.

The false jasmine genus contains one Asian and two North American species. One of the latter is the yellow, or Carolina, jasmine. Yellow jasmine has fragrant yellow flowers with a five-parted calyx; five-lobed, funnel-shaped corolla; five stamens with arrowhead-shaped anthers; and a solitary pistil. The fruit is a two-celled capsule. The roots contain a crystalline alkaloid called gelsemine, formerly used as an antispasmodic and to induce perspiration.
