What has ricinoleic acid?

2.10. Castor oil contains ricinoleic acid, a hydroxy monounsaturated fatty acid, as main constituent of its fatty acid profile. Castor oil, sometimes described as ricinoleic acid triglyceride, is the only commercially available vegetable oil containing hydroxy functionality of a fatty acid present abundantly (70–90%).

How do you make ricinoleic acid?

Ricinoleic acid is obtained from castor oil through hydrolysis, usually carried out under basic conditions. Industrially, ricinoleic acid is manufactured by saponification or fractional distillation of hydrolyzed castor oil (Fig. 21.11).

Where can I get ricinoleic acid?

mature castor plant
It is a major component of the seed oil obtained from mature castor plant (Ricinus communis L., Euphorbiaceae) seeds or in sclerotium of ergot (Claviceps purpurea Tul., Clavicipitaceae). About 90% of the fatty acid content in castor oil is the triglyceride formed from ricinoleic acid.

How do you extract ricinoleic acid from castor oil?

Ricinoleic acid was extracted from castor oil using alkaline ethanol followed by neutralization with an acid. 46 In brief, 50 g of dried castor oil and 200 mL of ethanol with 12 g of KOH were charged into a 500-mL round-bottom flask fitted with a water condenser and refluxed at 150°C for an hour.

How do you calculate linoleic acid?

Linoleic acid is an organic compound with the formula COOH(CH2)7CH=CHCH2CH=CH(CH2)4CH3. Both alkene groups are cis. It is a fatty acid sometimes denoted 18:2 (n-6) or 18:2 cis-9,12. A linoleate is a salt or ester of this acid.

Can we drink castor oil?

Ingesting too much castor oil can cause nausea, cramps, dizziness, and muscle weakness. Use it as advised by your doctor and don’t take it on an empty stomach. Because castor oil may help induce labor, pregnant women should avoid it.

Is ricinoleic acid toxic?

The available data demonstrate few toxic effects. Although animal studies indicate no significant irritant or sensitization potential, positive reactions to Ricinoleic Acid in selected populations with identified dermatoses did suggest that sensitization reactions may be higher in that population.

What is ricinoleic acid?

Ricinoleic acid, formally called 12-hydroxy-9- cis -octadecenoic acid is a fatty acid. It is an unsaturated omega-9 fatty acid and a hydroxy acid. It is a major component of the seed oil obtained from mature castor plant (Ricinus communis L., Euphorbiaceae) seeds or in sclerotium of ergot (Claviceps purpurea Tul., Clavicipitaceae).

What is ergot ricinoleic acid?

Ricinoleic acid, formally called 12-hydroxy-9- cis -octadecenoic acid is a fatty acid. It is an unsaturated omega-9 fatty acid and a hydroxy acid. It is a major component of the seed oil obtained from mature Castor plant ( Ricinus communis L., Euphorbiaceae) seeds or in sclerotium of ergot ( Claviceps purpurea Tul., Clavicipitaceae ).

What is the coproduct of zinc and ricinoleic acid?

The coproduct is 2-octanol. The zinc salt is used in personal care products such as deodorants. Ricinoleic acid exerts analgesic and anti-inflammatory effects. Ricinoleic acid specifically activates the EP3 prostanoid receptor for prostaglandin E2.

What is 12-hydroxy-9-cis-octadecenoic acid?

Ricinoleic acid, formally called 12-hydroxy-9-cis-octadecenoic acid is a fatty acid. It is an unsaturated omega-9 fatty acid and a hydroxy acid.
