HPTLC-Bioautography-MS-Guided Strategy for the Detection of Phthalides With Antimicrobial and Antioxidant Activities From Ligusticum chuanxiong Essential Oil.
Introduction: Antimicrobial resistance and free radical-mediated oxidative stress and inflammation involved in many pathological processes have become treatment challenges. One strategy is to search for antimicrobial and antioxidant ingredients from natural aromatic plants. This study established a rapid and high-throughput effect-component analysis method to screen active ingredients from Ligusticum chuanxiong essential oil (CXEO).
Objective: The study aims to screen phthalides with antimicrobial and antioxidant activities from CXEO by high-performance thin-layer chromatography (HPTLC)-bioautography combined with HPLC-TOF/MS method.
Methods: Antimicrobial activity was evaluated by disc diffusion and micro broth dilution methods. Antioxidant capacity was performed by DPPH scavenging test. Phthalides in CXEO were identified using HPLC-TOF/MS method. HPTLC-bioautography technique was established to screen phthalides of antifungal and antioxidant activities.
Results: CXEO had significant inhibitory activity against Candida albicans, weak or undetected inhibitory activity against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. For tested strains of C. albicans, inhibition zone diameters ranged from 13 to 17 mm, and MICs were from 0.5 to 2 mg mL-1. CXEO also had strong antioxidant activity, IC50 value for scavenging DPPH free radicals was 1.014 ± 0.014 mg mL-1. Nine phthalides in CXEO were tentatively identified. Ligustilide and senkyunolide A were screened to have both antimicrobial activity against C. albicans and strong DPPH scavenging property.
Conclusion: HPTLC-bioautography-MS-guided strategy is very practical for high-throughput screening of antifungal and antioxidant phthalides from CXEO. In vitro experiments have shown that phthalides and CXEO have good biological activities, which may be used to the treatment of C. albicans infection or oxidative stress damage caused by various diseases. The therapeutic potential should be validated in vivo in the future.
期刊介绍：
Phytochemical Analysis is devoted to the publication of original articles concerning the development, improvement, validation and/or extension of application of analytical methodology in the plant sciences. The spectrum of coverage is broad, encompassing methods and techniques relevant to the detection (including bio-screening), extraction, separation, purification, identification and quantification of compounds in plant biochemistry, plant cellular and molecular biology, plant biotechnology, the food sciences, agriculture and horticulture. The Journal publishes papers describing significant novelty in the analysis of whole plants (including algae), plant cells, tissues and organs, plant-derived extracts and plant products (including those which have been partially or completely refined for use in the food, agrochemical, pharmaceutical and related industries). All forms of physical, chemical, biochemical, spectroscopic, radiometric, electrometric, chromatographic, metabolomic and chemometric investigations of plant products (monomeric species as well as polymeric molecules such as nucleic acids, proteins, lipids and carbohydrates) are included within the remit of the Journal. Papers dealing with novel methods relating to areas such as data handling/ data mining in plant sciences will also be welcomed.
