Studies on essential oils, Part 41. Chemical composition, antifungal, antioxidant and sprout suppressant activities of coriander (Coriandrum sativum) essential oil and its oleoresin

Abstract

Gas chromatography-mass spectrometry (GC-MS) analysis of the seed oil of coriander (Coriandrum sativum) showed the presence of 52 components, accounting for 98.45% of the total oil. The major components were linalool (75.30%), geranyl acetate (8.12%) and α α α α α-pinene (4.09%). Its oleoresin showed the presence of 28 components. Oleic acid (36.52%), linoleic acid (33.2%) and palmitic acid (11.05%) were the major components. The antifungal activities of coriander oil and its oleoresin against eight fungi were evaluated using the inverted petriplate and food poison techniques. Using the inverted petriplate method, the essential oil was found to be highly active against Curvularia palliscens, Fusarium oxysporum, Fusarium moniliforme and Aspergillus terreus. In the case of the oleoresin, more than 50% mycelial zone inhibition was obtained for the fungi Fusarium oxysporum, Aspergillus niger and Aspergillus terreus. Using the food poison technique, the essential oil showed 100% inhibition on the growth of A. terreus, A. niger, F. graminearum and F. oxysporum, whereas its oleoresin showed weaker fungitoxic activity, exhibiting 100% inhibition on the growth of F. oxysporum only. The oleoresin had a better antioxidant activity for sunflower oil than essential oil and synthetic antioxidants, BHA and BHT. The oil was also found to exert strong sprout suppressant activity (SSA) for potatoes. Copyright

Antifungal activity of thyme, summer savory and clove essential oils against Aspergillus flavus in liquid medium and tomato paste

“…In our opinion major components of thyme (thymol (33.14%), carvacrol (19.59%), linalool (16.00%) and -cymene (10.30%)), summer savory (carvacrol (24.50%), thymol (23.12%) andterpinene (20.72%)) and clove oil (eugenol (63.37%), -caryophyllene (15.94%) and eugeyl acetate (13.14%)) have key roles in their antifungal activities. Antifungal activities of these compounds have been reported by others (Burt, 2004;Nguefack, Letha, Amvam Zollob, & Mathura, 2004;Singh, Maurya, Lampasona, & Catalan, 2006). However, the mechanisms of action of these compounds have not been completely elucidated.…”

Salinity impact on fruit yield, essential oil composition and antioxidant activities of Coriandrum sativum fruit extracts

“…Different studies have proven that coriander extracts and essential oil exhibit antioxidant activities (Guerra, Melo, & Filho, 2005;Singh, Maurya, de Lampasona, & Catalan, 2006). Wangensteen, Samuelsen, and Malterud (2004) demonstrated that coriander leaves showed stronger antioxidant activity, tested by DPPH, the inhibition of 15-lipoxygenase and inhibition of Fe 2+ -induced porcine brain phospholipid peroxidation, than the seeds.…”

Antifungal activity of coriander (Coriandrum sativum L.) essential oil in tomato sauce

“…Previous studies have investigated the antifungal activity of EO against A. flavus and A. fumigaths [21]. Some authors also described the antifungal activity of C. sativum EO against A. niger [22], A. terreus, A. flavus, Trichothecrum roseum, Fusarium graminearum, Fusarium oxysporum, Fusarium moniliforme and Curvularia palliscens [23]. Antifungal activity of the CEO was tested on Penicillium lilacinum and A. niger, MIC was determined 2.5 and 2.3 mg/mL, respectively [24].…”
