Chemical Characterization and Antifungal Activity of Blue Tansy ( Tanacetum annuum) Essential Oil and Crude Extracts against Fusarium oxysporum f. sp. albedinis, an Agent Causing Bayoud Disease of Date Palm. Antibiotics (Basel) 2023; 12:1451. [PMID: 37760747 PMCID: PMC10526058 DOI: 10.3390/antibiotics12091451] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 09/13/2023] [Accepted: 09/14/2023] [Indexed: 09/29/2023] Open
Abstract
Tanacetum annuum L. is a Mediterranean plant, commonly known as Blue Tansy due to its blue colour as an essential oil, which is widely used for medicinal purposes. However, there are no studies on the bioactive compounds (especially, phenolic compounds) and the biological properties of their organic extracts. Herein, the purpose of the present work was to investigate the chemical composition of the essential oil and crude extracts of the T. annuum aerial parts collected from northern Morocco and to evaluate their antioxidant and antifungal activity against Fusarium oxysporum f. sp. albedinis, an agent causing Bayoud disease of the date palm, an important food source and commercial perennial crop in the Sahara and North Africa. Chemically, Folin-Ciocalteu and aluminium chloride colourimetric methods were used to determine the total phenolic (TPC) and total flavonoid (TFC) contents, respectively; polyphenols were characterized using HPLC-MS, while GC-MS was used to analyse the essential oil composition. Moreover, the evaluation of antioxidant and antifungal activities was carried out using the DPPH test and microdilution method, respectively. The results showed that the three T. annuum parts (stems, leaves and flowers) extracts contained important TPC and TFC with values varied between 51.32 and 116.32 mg/g of dry crude extract (DCE). HPLC-MS analysis revealed the identification and quantification of 19 phenolic acids and flavonoids with an emphasis on apigenin 7-glucoside (4540 µg/g of dry weight (DW)), luteolin 7-glucoside (2804 µg/g DW) and salicylic acid (1878 µg/g DW). Additionally, 39 biomolecules were identified in the essential oil using GC-MS, which were predominated by camphor (16.69%), α-pinene (12.37%), bornyl acetate (11.97%) and limonene (11.10%). The methanolic and hydro-methanolic extracts of T. annuum parts demonstrated a strong antioxidant property with IC50 values ranging between 0.22 and 0.65 mg/mL. Concerning antifungal activity, the essential oil and crude extracts of the Moroccan Blue Tansy exhibited a potent capacity against F. oxysporum f. sp. albedinis at low concentrations, with MIC and MFC values of 3.33 and 4.58 µL/mL for the essential oil and values of 3.33 and 9.17 mg/mL for crude extracts, respectively. Overall, these results demonstrated T. annuum as an important source of bioactive compounds and contribute significantly to the potential of using essential oils and extracts for controlling the Bayoud disease of date palms. Moreover, the finding suggests that T. annuum can be highly useful for phytosanitary and pharmaceutical industries.

Gamma-irradiation effect on the chemical composition and antibacterial activity of the moroccan tanacetum annuum L. essential oil. Heliyon 2023; 9:e16625. [PMID: 37292271 PMCID: PMC10245259 DOI: 10.1016/j.heliyon.2023.e16625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Revised: 05/10/2023] [Accepted: 05/23/2023] [Indexed: 06/10/2023] Open
Abstract
The primary objective of the present inquiry was to assess the impact of gamma irradiation on the chemical composition and antibacterial potential of the essential oil extracted from the aerial parts of Moroccan Tanacetum annuum L. to this end, two distinct irradiation doses of 5 kGy and 10 kGy were administered to the essential oil, and the resultant effects were evaluated via analysis of the oil's chemical composition and antibacterial activity. The study findings have revealed that irradiation technology possesses the remarkable ability to modulate the concentrations of specific chemical constituents in a manner that effectively amplifies the antibacterial activity of the essential oil. Moreover, the technology has evinced the generation of novel compounds while also demonstrating the eradication of certain pre-existing ones upon the oil's exposure to irradiation. These discoveries have emphasized the potential of irradiation technology for augmenting the chemical profile of essential oils, thereby mitigating the risk of contamination via microbiological, physical, or chemical means, ultimately enhancing the therapeutic efficacy of the plant and its essential oil. Furthermore, the results of this study signify the possibility of harnessing irradiation technology in the production of various natural products and essential oils. The present research has thus broadened the horizons for the application of irradiation technology in advancing the potency and safety of essential oils, paving the way for a diverse range of applications in different fields, such as medicine.
