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

Hydrolytic Degradation and Drug Release of Ricinoleic Acid–Lactic Acid Copolyesters

Pharmaceutical Research, 2006
A systematic study on the degradation and drug release from L-lactic acid and ricinoleic-acid-based copolyesters is reported. These copolyesters were synthesized by ring opening polymerization (ROP), melt condensation (COND) and transesterification (TRANS) of high molecular weight poly(lactic acid) (PLA) with ricinoleic acid (PLA-RA), and ...

Antimicrobial activity of some ricinoleic acid oleic acid derivatives

Journal of the American Oil Chemists' Society, 1961
AbstractRicinoleic and acid oleic acid derivatives were screened for their antimicrobial activity, under optimum growing‐conditions, against several species of bacteria, yeasts, and molds. Several ricinoleic acid derivatives and petroselinic (iso‐oleic) acid exhibited considerable activity; in fact, their activity against some micro‐organisms was ...

Ricinoleic Acid in Common Vegetable Oils and Oil Seeds

Lipids, 2008
AbstractAn original gas chromatography/mass spectrometry method for quantifying trace amounts of ricinoleic acid (12‐hydroxy‐cis‐9‐octadecenoic acid) is detailed. Data are presented on trace amounts of ricinoleic acid found in several common vegetable oils and oils extracted from common oil seeds: e.g., ca. 30 ppm in commercial olive oil was the lowest

Synthesis and biological evaluation of ricinoleic acid-based lipoamino acid derivatives

Bioorganic & Medicinal Chemistry Letters, 2016
A series of novel ricinoleic acid based lipoamino acid derivatives were synthesized from (Z)-methyl-12-aminooctadec-9-enoate and different l-amino acids (glycine, alanine, phenyl alanine, valine, leucine, isoleucine, proline and tryptophan). The structures of all the prepared compounds were characterized by 1H NMR, 13C NMR and mass spectral studies ...
