So, we can conclude that the oil content in the prickly seed will be between 5 to 10% according to the cultivar used for the extraction. And finally, we can say that to get 1 kg of oil, between 300 and 500kg of fresh fruits will be needed.
The oil processed from the seeds is characterized by a high degree of unsaturation wherein linoleic acid is the major fatty acid (56.1–77%). Oleic (C18:1) and linoleic (C18:2) acids can count for more than 80%  of the total fatty acids.
The sterol fraction is usually about 1% of TL withβ-sitosterol as sterol marker, representing 72% of the total sterol content in seed oil.
Originally native to India and Indonesia, vetiver grows wild in all tropical and subtropical latitudes. Vetiver is an herbaceous, perennial, bushy plant that can grow up to two meters tall. Its long, rigid, narrow leaves. Vetiver is most closely related to Sorghum but shares many morphological characteristics with other fragrant grasses, such as lemongrass (Cymbopogon citratus), citronella (Cymbopogon nardus, C. winterianus), and palmarosa (Cymbopogon martinii).
The name vetiver first appeared in France in the 19th century. It comes from the Tamil vettiveru, from vetti, meaning "pull out" and ver meaning "root", thus translating as "dug up roots" or "unearthed roots." In many Indian states, it is also known as Cus-Cus, Khus-Khus, or Khas-Khas. Vetiver is also written "vetyver". Vetiver scent was very popular in ancient India, when Indian brides-to-be were given an ointment made from vetiver roots. The stems and leaves were used as thatch to roof houses, or were braided into mats.
Vetiver roots are the source of the precious woody, earthy smell that is characteristic of the plant. They also play an ecological role in preventing soil erosion caused by flooding and runoff of rainwater.
Indonesia, India and Haiti are the main producers of the essential oil. Javanese vetiver is characterized by its strong smoky notes.
