Objective: The aim of this study was to investigate chemical constituents of leaves and seeds of Corchorus olitorius since no phytochemical investigation had been done previously in Iraq.Methods: Leaves and seeds of C. olitorius were defatted by maceration in hexane for 24 h. The defatted plant materials were extracted using Soxhlet apparatus, the aqueous methanol 85% as a solvent extraction for 24 h, and fractionated by petroleum ether, chloroform, ethyl acetate, and n-butanol. The ethyl acetate, n-butanol, and n-butanol after hydrolysis fractions for each part (leaves and seeds) were analyzed by high-performance liquid chromatography (HPLC) and high-performance thin-layer chromatography (HPTLC) for its phenolic acid and flavonoid contents. The petroleum ether fraction from the leaves was analyzed using Gas chromatography/mass spectrometer (GC/MS). Flavonoids and phenolic acid derivative were isolated from the ethyl acetate of leaf fraction and n-butanol after hydrolysis fraction of the seeds and identified by mass spectrometry, infrared, HPLC, and HPTLC.Results: The different chromatographic and spectroscopic results revealed the presence of luteolin, quercetin, astragalin, isoquercetin, catechins, and 3,5-dicaffeoylquinic acid (3,5-DCQA) in both leaves and seeds of C. olitorius and also 17-octadecynoic acid, 9-octadecanoic acid (oleic acid), hexadecenoic acid (palmitic acid), 9,12-octadecanoic acid (linoleic acid), octadecadien-1-ol (β-sitosterol), and α-tocopherol (Vitamin E) in the petroleum ether fraction of C. olitorius leaves.Conclusion: The results of the current study proved the presence of 3,5-DCQA, astragalin, and isoquercetin in the ethyl acetate fraction of C. olitorius leaves and catechin in the n-butanol after hydrolysis fraction of C. olitorius seeds.

Abstract Background Many plants of genus Cordia are traditionally used as astringent, anti-inflammatory, anthelminthic, antimalarial, diuretic, febrifuge, appetite suppressant and cough suppressant and to treat urinary infections, lung diseases and leprosy. The aim of the study is to determine the total phenolic and flavonoid contents of total ethanol extract and different fractions of C. myxa L. leaves, in addition to evaluation of some pharmacological activities including antioxidant, anti-inflammatory, analgesic, antipyretic and antidiabetic effects. Methods Air dried powder of C. myxa leaves were extracted using 95% ethanol and fractionated successively with petroleum ether, dichloromethane, ethyl acetate and finally with n-butanol. The fractions were concentrated and then investigated for their antioxidant, anti-inflammatory, analgesic, antipyretic and antidiabetic activities using phosphomolybidinum and DPPH assays, carrageenan-induced paw edema, hot plate, yeast -induced pyrexia and streptozotocin-induced hyperglycemia methods, respectively. Results The ethyl acetate fraction showed the highest antioxidant activity with high phenolic and flavonoid contents (31.03 ± 0.15 mg gallic acid equivalent/g dried weight and 811.91 ± 0.07 mg rutin equivalent/g dried weight, respectively). Dichloromethane and ethyl acetate fractions exhibited higher anti-inflammatory activity with percentages of inhibition 45.16% and 40.26%, respectively, which were quite comparable to that of indomethacin (51.61%). The petroleum ether and dichloromethane fractions showed the highest analgesic activity with reaction time 289.00 ± 3.00 and 288.33 ± 20.82, respectively. Evaluation of antipyretic activity revealed that the total ethanol extract and different fractions showed high antipyretic activities after 2 h, which were very close to that of the standard acetyl salicylic acid with a rapid onset (30 min). The total ethanol extract and the petroleum ether fraction exhibited the most potent hypoglycemic effect with a significant reduction in blood glucose level especially after 3 h to 95.67 ± 5.77 mg/dl and 87.67 ± 10.26 mg/dl, respectively and percentages decrease in blood glucose level were 68.22% and 70.78%, respectively. Conclusion Cordia myxa L. extract and fractions exhibited antioxidant, anti-inflammatory analgesic, antipyretic and antidiabetic activities which may be attributed by the presence of active phytoconstituents.
