| Introduction | Castor oil is the fat oil extracted from the seeds of Ricinus communis, at room temperature for almost colorless or microstrip yellow clear viscous liquid, slightly odorous, light flavor and then micro-Xin. Insoluble in water, soluble in ethanol, benzene and carbon disulfide, and anhydrous ethanol, ether, chloroform or acetic acid can be arbitrary mixture, but insoluble in mineral oil. Relative density 0.956~0.969(25 deg C), refractive index 1.478~1.480, acid value <= 2.0, saponification value 176~186, iodine value 82~90. Castor oil is a glyceride of higher fatty acids mainly composed of ricinoleic acid (12-hydroxyoctadec-9-enoic acid) and oleic acid. R1,R2 and R3 in the molecule can be the same or different, including ricinoleic acid 80% ~ 88%, oleic acid 3%~ 9%, there are Palmitic acid, Stearic acid, linoleic acid, linolenic acid, dihydroxystearic acid (dihydroxystearic acid), the composition of the glycerides of triricinoleate (Tririci-nolein) 68.2%, diricinoleate (Diricinolein) 28.0%, a ricinoleate (Monoricinolein)2.9% and non ricinolein (Nonricinolein) 0.9%. Ash contains a large amount of calcium, iron, silicon, the other contains inorganic elements of aluminum, copper, magnesium and a small amount of manganese, titanium, nickel, zinc and so on. |
| pharmacological action | Castor oil is a stimulant laxative. In the duodenum by the role of lipase and bile, saponification into glycerol and small intestine mucosa irritation of ricinoleic acid sodium and cause intestinal peristalsis, and has the effect of Runchang, mainly in the small intestine, defecation 4~6 hours after taking medicine. |
| Clinical application | castor oil can be used in the following fields: 1, for habitual constipation. 2, because the drug can make the intestinal gas and feces completely empty, also suitable for rectal endoscopy, intestinal surgery and gastrointestinal X-ray examination before used as laxative. 3, used as a food poisoning agent. |
| preparation | preparation method: castor seeds can be washed, steamed and fried, and then deodorized, castor oil was prepared by decolorization. |
| toxicity | ADI 0-0.7(FAO/WHO,2001). GRAS(FDA,§ 172.876,2000). |
| usage limit | FDA, § 172.876(2000): Hard Candy, mg/kg; as a coating agent for vitamin and inorganic salt tablets, GMP is limited. FEMA(mg/kg): Beverage 1.5~140, cold drink 3.0~540, Candy 3.0~410, baked goods 210. |
| Use | used in the production of Sebacic acid, cold-resistant plasticizer, lubricating oil, perfume, penetrating agent for textile industry, emulsifiers, etc. used in the preparation of laxatives and zinc preparations leather fatliquor. Preparation of Sulfated Castor oil. Leather finishing agent, brightener. used in the manufacture of plasticizer, dibasic acid, polyurethane coating, rubber, adhesive, fatty acid, surfactant, insulating oil, hydraulic oil, lubricating oil, Turkey red oil, soap, polyamide -11 fiber, etc. Castor oil is dehydrated to conjugated double bond dry oil. A variety of products can be obtained by hydrogenation under different conditions, and therefore, it is widely used in various industrial sectors. Castor oil is a stimulant laxative. It mainly acts on the small intestine and is used for catharsis. release agent; Carrier solvent; Protective coating. used in the manufacture of Turkey red oil, soap, plastic, lubricating oil, etc. plasticizer, base material |
| production method | from Ricinus communis seeds of annual tall herb Ricinus communis, the oil content of the seed is about 45% ~ 60%. The cold-pressed oil of castor bean is added to the pre-prepared 3% sodium hydroxide solution, stirred and heated to 60-65 ℃ to fully saponify the free fatty acids in the oil, washed with hot water at 95-100 ℃, and left to stand, wash water was removed and washed repeatedly for several times. Below 105 ℃ (7.98-14.63kPa) dehydration, add white clay and activated carbon stirring, decolorizing for half an hour, pressure filtration, castor oil (medicinal). extracted from castor seeds. |
