Cyclopropenoid fatty acids in seed oils ofSida acuta andSida rhombifolia (malvaceae)

Abstract

Seed oils ofSida acuta andSida rhombifolia were found to contain sterculic (11.0, 10.8%) and malvalic (1.7, 2.0%) acids respectively, in addition to the normal fatty acids. Co‐occurrence of these acids was established by gas liquid chromatography of the silver nitrate‐methanol‐treated methyl esters usingSterculia foetida esters as a reference standard. This gas liquid chromatography technique of quantitation was found most suitable to estimate these acids in low level cyclopropenoid acid‐containing seed oils.

Constituintes químicos e atividade antioxidante de Sida galheirensiS Ulbr. (Malvaceae)

“…Estudos farmacológicos utilizando extratos desta planta indicaram sua atividade antinociceptiva e antiinflamatória 4 . Investigações fitoquímicas com espécies do gênero Sida mostraram a presença de ácidos graxos [5][6][7][8][9] , diterpenos 7 , esteróides 10,11 , flavonóides 12,13 e compostos nitrogenados 14,15 . Os radicais livres desempenham papel importante no organismo, mas o efeito cumulativo desses radicais está implicado em doenças, tais como câncer, ateroscleroses, isquemia cerebral e envelhecimento 16 .…”

Structural Assessment of Chemical Constituent of Sidaguri (Sida rhombifolia Linn) and Its Ability to Inhibit Cyclooxygenase

“…These compounds was reported to show antibacterial activity against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Salmonella Typhimurium [6], while root bark of sidaguri only showed antibacterial activity against facultative anaerob Gram + bacteria, Enteroc faecalis but no antibacterial activity against obligate anaerob bacteria; Actinomyces spp [3]. Another investigations on the leaves of S. rhombifolia found aliphatics group cyclopropenoid fatty acid, myrstic acid, palmitic acid, stearic acid, oleic acid, and linoleic acid [12]. More studies should be carried out to examine other functional groups contained in the root bark of sidaguri and its biological activities against other bacteria.…”

Epoxy and cyclopropenoid fatty acids in Amaranthus paniculatus seed oil

“…However, the direct TLC and 2,4-DNP TLC plastic formulations and in the preparation of long-chain compounds. Oils containing cyclopropenoid fatty acids have attracted much attention owing to their biological effects on animals and their co-carcinogenic Properties (Ahmad et al 1976).…”
