Macrolactones and Polyesters from Ricinoleic Acid

Biomacromolecules, 2005
A systematic study on the synthesis, characterization, and polymerization of ricinoleic acid (RA) lactone is reported. Ricinoleic acid lactones were synthesized by refluxing pure ricinoleic acid in chloroform (10 mg/mL) with dicyclohexylcarbodimide and (dimethylamino)pyridine as catalyst.

Stable polyanhydride synthesized from sebacic acid and ricinoleic acid

Journal of Controlled Release, 2017
Poly(anhydride) are unstable and prone to hydrolytic degradation and depolymerisation via anhydride interchange. They are stored at -20°C, packed under inert atmosphere until use. We synthesized a new poly(anhydride) from ricinoleic (RA) and sebacic (SA) acid with alternating ester-anhydride structure that is stable at 25°C for over 18months.

Lactic Acid and Ricinoleic Acid Based Copolyesters

Macromolecules, 2005
Copolyesters based on purified ricinoleic (RA) and lactic (LA) acids with different RA:LA ratios were synthesized by thermal polycondensation and by transesterification of high molecular weight poly(lactic acid) (PLA) with ricinoleic acid and repolyesterification.

Ricinoleic Acid Catabolism in Peroxisomes

Botanica Acta, 1991
AbstractPeroxisomes from castor bean endosperm and mung bean hypocotyl completely degrade ricinoleic acid (12‐D‐hydroxy‐9‐cis‐octadecenoic acid) to acetyl‐CoA. Concomitant NADH formation occurred with a stoichiometry of 9 nmol NADH formed per 1 nmol ricinoleate degraded.

Synthesis of phosphatidylcholines containing ricinoleic acid

Tetrahedron, 2001
Abstract 1,2-Diricinoleoyl- and 1-ricinoleoyl-2-oleoyl-sn-glycero-3-phosphocholine were synthesised with good yields. The synthesis started with the preparation of ricinoleic acid from castor oil. The choice of a suitable agent to protect the –OH group of ricinoleic acid was a key factor to afford the final products.

Final Report on the Safety Assessment of Ricinus Communis (Castor) Seed Oil, Hydrogenated Castor Oil, Glyceryl Ricinoleate, Glyceryl Ricinoleate SE, Ricinoleic Acid, Potassium Ricinoleate, Sodium Ricinoleate, Zinc Ricinoleate, Cetyl Ricinoleate, Ethyl Ricinoleate, Glycol Ricinoleate, Isopropyl Ricinoleate, Methyl Ricinoleate, and Octyldodecyl Ricinoleate1

International Journal of Toxicology, 2007
The oil derived from the seed of the Ricinus communis plant and its primary constituent, Ricinoleic Acid, along with certain of its salts and esters function primarily as skin-conditioning agents, emulsion stabilizers, and surfactants in cosmetics, although other functions are described.

Ricinoleic acid inLinum mucronatum seed oil

Lipids, 1971
AbstractLinum mucronatum seed oil contains 15% ricinoleic [(+)‐12‐D‐hydroxy‐cis‐9‐octadecenoic] acid, previously unknown in the Linaceae. Identification was made by IR, gas liquid chromatography, nuclear magnetic resonance, ozonolysis and mass spectrometry. Other major components of the oil are oleic acid (24%) and linoleic acid (48%).

Hydroboration-oxidation of ricinoleic acid derivatives

Russian Journal of Organic Chemistry, 2008
The regioselectivity in the hydroboration-oxidation of ricinoleic acid derivatives only slightly depends on the configuration of the optically active center: the fraction of the resulting 1,3-diol is larger by 6–10% than that of the 1,4-isomer.

CLA production from ricinoleic acid by lactic acid bacteria

Journal of the American Oil Chemists' Society, 2003
AbstractThe ability to produce CLA from ricinoleic acid is widely distributed in lactic acid bacteria. Washed cells of Lactobacillus plantarum JCM 1551 were selected as a potential catalyst for CLA production from ricinoleic acid. Cells cultivated in medium supplemented with a mixture of α‐linolenic acid and linoleic acid showed enhanced CLA ...

Polyesters of Ricinoleic Acid and Lactic Acid

2009
Abstract Properties of Special Interest Polyester copolymers of ricinoleic acid (RA) with lactic acid (LA) degrade in physiological medium giving an almost zero-order weight loss, with a 20–40% loss after 60 days of incubation. Lactic acid release to the degradation solution is proportional to weight loss of the polymer samples. The main
