“…Also, p-cymene and (E)-β-ocimene were found to be significant compounds in leaf essential oil at 11.2 and 9.1% against 3.9 and 2.7% in the flower essential oil, respectively. It is well known that different parts of the same plant may include different phytochemicals (37,38). This variation can be elucidated by the presence of different secretory structures in different plant parts.…”

The chemical composition of leaf and flower essential oils of Origanum onites L. were analyzed using Thermo Scientific TSQ GC-MS/MS. Also, antioxidant activities of the leaf and flower essential oils were investigated by using DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging activity and β-carotene linoleic acid assays. BHA (Butylated hydroxyanisole) and BHT (Butylated hydroxytoluene) were used as standards. The essential oil yields of O. onites were 1.75% for leaves and 4.25% for flowers. A total of twenty-three compounds representing 99.9% of leaf oil and twenty-four compounds constituted 99.6% of the flower oil were determined. Oxygenated monoterpenes were detected at a high percentage (69.2%) in leaf essential oil, and carvacrol (64.9%) was determined as the main compound. Also, flower essential oil was dominated by sesquiterpene hydrocarbons (73.5%), and α-cubebene (36.4%) was determined as a primary compound. For leaf oil, a high antioxidant capacity was determined, primarily due to carvacrol and p-cymene.

“…Zanthoxylum avicennae belongs to Rutaceae , and is mainly distributed around southern coastal area of China and parts of Southeast Asia, such as Hainan, Fujian, Guangxi, the Philippines, and Vietnam [1]. Z. avicennae has often been used to treat and relieve many illnesses, such as multi-phlegm, rheumatism, sore throat, jaundice, insect and snake bites, vomiting and diarrhea, repel Ascaris , and digestive system diseases in clinical and in traditional Chinese medicine [2,3,4,5,6,7,8]. Therefore, Z. avicennae deserves great research value and the bioactive substances from Z. avicennae have attracted researchers’ attention.…”

Screening Effective Antifungal Substances from the Bark and Leaves of Zanthoxylum avicennae by the Bioactivity-Guided Isolation Method

et al. 2019

To find good antifungal substances by the bioactivity-guided isolation method, we tracked down the effective antifungal substances in the bark and leaves of Zanthoxylum avicennae, and isolated three antifungal compounds 1, 2, and 3. The structures were identified as xanthyletin, luvangetin, and avicennin by 1H-NMR, 13C-NMR, and HRMS spectra. Particularly, compound 2 had several isomers, and the 1H-NMR spectra of 2 in different solvents showed a significant difference. To determine the stereo structure of 2, a single crystal was prepared and identified by X-ray diffraction as Luvangetin. Moreover, the difference of 1H-NMR data of 2 between in solvent dimethyl sulfoxide-d6 (DMSO-d6) and deuterated chloroform (CDCl3), and other reported isomers were discussed for the first time. The bioassay results indicated that the three compounds 1, 2, and 3 displayed low to high antifungal activities against tested phytopathogenic fungi. In particular, all compounds 1, 2, and 3 showed excellent antifungal activities against Pyricularia oryzae and Z. avicennae, with the values of half maximal effective concentration (EC50) ranging from 31 to 61 mg/L, and compound 3 was also identified as a more potent inhibitor against Fusaium graminearum (EC50 = 43.26 ± 1.76 mg/L) compared with fungicide PCA (phenazine-1-carboxylic acid) (EC50 = 52.34 ± 1.53 mg/L). The results revealed that compounds 1, 2, and 3 were the main antifungal substances of Z. avicennae, and can be used as lead compounds of a fungicide, which has good development value and prospect.
