“…Previously, there were reports on the phytotoxic/allelopathic potential of volatile oils produced by Artemisia species. Jiang et al studied the chemical profile and phytotoxic activity of the essential oil extracted from A. sieversiana , which led to the identification of α-thujone (64.46%) and eucalyptol (10.15%) as the most abundant constituents [ 56 ]. Both the major oil components and the essential oil possessed significant phytotoxic effect against the receiver species A. retroflexus , Medicago sativa , P. annua and Pennisetum alopecuroides , with their IC 50 values ranged from 1.55~6.21 mg/mL (α-thujone), 1.42~17.81 mg/mL (eucalyptol), 0.23~1.05 mg/mL (the mixture of α-thujone and eucalyptol) and 1.89~4.69 mg/mL (the essential oil).…”

“…Eucalyptol and camphor (purity 98%) were purchased from Sigma-aldrich Co. (St. Louis, USA). The volatile oils, eucalyptol, camphor and their mixture were diluted in 0.5% acetone in distilled H 2 O to yield 0.2, 0.5, 1.5, 3, 5 mg/mL solutions, with acetone as the initial solvent (our previous experiment showed acetone at such concentration did not significantly affect seedling growth of the test plants [ 37 , 56 ]. Five ml of 0.5% acetone in distilled H 2 O (control) or diluted solutions were added to each petri dish (9 cm in diameter) which contained 10 test seeds.…”

The chemical profile and allelopathic effect of the volatile organic compounds (VOCs) produced by a dominant shrub Serphidium kaschgaricum (Krasch.) Poljak. growing in northwestern China was investigated for the first time. Serphidium kaschgaricu was found to release volatile compounds into the surroundings to affect other plants’ growth, with its VOCs suppressing root elongation of Amaranthus retroflexus L. and Poa annua L. by 65.47% and 60.37% at 10 g/1.5 L treatment, respectively. Meanwhile, volatile oils produced by stems, leaves, flowers and flowering shoots exhibited phytotoxic activity against A. retroflexus and P. annua. At 0.5 mg/mL, stem, leaf and flower oils significantly reduced seedling growth of the receiver plants, and 1.5 mg/mL oils nearly completely prohibited seed germination of both species. GC/MS analysis revealed that among the total 37 identified compounds in the oils, 19 of them were common, with eucalyptol (43.00%, 36.66%, 19.52%, and 38.68% in stem, leaf, flower and flowering shoot oils, respectively) and camphor (21.55%, 24.91%, 21.64%, and 23.35%, respectively) consistently being the dominant constituents in all oils. Eucalyptol, camphor and their mixture exhibited much weaker phytotoxicity compared with the volatile oils, implying that less abundant compounds in the volatile oil might contribute significantly to the oils’ activity. Our results suggested that S. kaschgaricum was capable of synthesizing and releasing allelopathic volatile compounds into the surroundings to affect neighboring plants’ growth, which might improve its competitiveness thus facilitate the establishment of dominance.

“…The EO of A. sieversiana was found to exhibit significant phytotoxic activity against Amaranthus retroflexus, Medicago sativa, Poa annua, and Pennisetum alopecuroides, with IC 50 values ranging from 1.89 -4.69 mg/mL. [16] Razavi et al reported that the EO of A. austriaca significantly reduced the seed germination, as well as the shoot and root length, of Lactuca sativa at concentrations higher than 1 mg/mL. [17] The EO of A. pedemontana (flowering stage) inhibited the root and leaf growth of Lolium perenne by 30 % at 0.4 μg/μL.…”

“…[15] Volatiles produced by certain Artemisia species have been reported to be highly phytotoxic, and they are considered effective allelochemicals that favor the establishment of the plant's own dominance. [16][17][18] To learn more about volatiles released by plants, the classic Clevenger essential oil hydrodistillation and HS-SPME methods are often used to determine their chemical profiles. [19] Unlike HS-SPME, the HD method yields an EO which can be further used for bioactivity determination.…”

The chemical profile and allelopathic action of the volatiles produced by Artemisia selengensis were studied. Artemisia selengensis was found to release volatile chemicals to the environment to influence other plants' growth, which suppressed the root length of Amaranthus retroflexus and Poa annua by 50.46 % and 87.83 % under 80 g/1.5 L treatment, respectively. GC/MS analysis led to the identification of 41 compounds (by hydrodistillation, HD) and 48 compounds (by headspace solid-phase microextraction, HS-SPME), with eucalyptol (15.45 % by HD and 28.09 % by HS-SPME) being detected as the most abundant constituent. The essential oil (EO) of A. selengensis completely inhibited the seed germination of A. retroflexus and P. annua at 1 mg/mL and 0.5 mg/mL, respectively. However, eucalyptol displayed much weaker activity compared with the EO, indicating that other less abundant constituents might contribute significantly to the EO's activity. Our study is the first report on the phytotoxicity of A. selengensis EO, suggesting that A. selengensis might release allelopathic volatile agents into the environment that negatively affect other plants' development so as to facilitate its own dominance; the potential value of utilizing A. selengensis EO as an environmentally friendly herbicide is also discussed.

“…[33] The IC 50 for Artemisia sieversiana essential oil against A. retroflexus L. was 1.98, while it was 3.79 and 4.31 mg mL À 1 for its two major components α-thujone and eucalyptol, respectively, indicating the possible involvement of synergistic effect of these two compounds. [34] Worth noted, despite being less potent than the positive control 2,4-D isooctyl ester, AcOEtE as a natural herbicide has lots of advantages such as being health and environment friendly, and low cost, making it much interesting in organic farming practices. As far as we know, our present study represents the first report of the herbicidal effect of pomelo seed.…”

Pomelo seeds (PS) are important by-product of pomelo fruits (Citrus grandis Osbeck). The value-added utilization of PS remains highly challenged. This study aimed to investigate the utilization potential of PS as natural antioxidant, antibacterial, herbicidal agents, and their functional components. The ethanolic extract (EE) of PS and its four fractions as PEE (petroleum ether extract), AcOEtE (ethyl acetate extract), BTE (butanol extract), and WE (water extract), were prepared and biologically evaluated. BTE exhibited the best antioxidant activity among all these extracts, in both ABTS (2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt) and FRAP (ferric reducing antioxidant power) assays. AcOEtE was superior to other extracts in herbicidal assay against both Festuca elata Keng (IC 50 of 0.48 mg mL À 1 ) and Amaranthus retroflexus L. (IC 50 of 0.94 mg mL À 1 ). Meanwhile, both AcOEtE and BTE demonstrated inhibitory effects against Bacillus subtilis, Escherichia coli, and Xanthomonas citri subsp. citri, with MIC ranging 2.5 -5.0 mg mL À 1 . Furthermore, the primary chemical components involving naringin, deacetylnomilin, limonin, nomilin, and obacunone, were quantified in all these extracts. PCA (principal component analysis) suggested that naringin might highly contribute to the antioxidant activity of PS, and the herbicidal activity should be ascribed to limonoids. This study successfully identified AcOEtE and BTE as naturally occurring antioxidant, antibacterial, and herbicidal agents, showing application potential in food and cosmetics industries, and organic farming agriculture.
