Abstract
Aristolochic Acid I (AAI) is an environmental and foodborne toxin found in the Aristolochia and Asarum species of plants that are widespread all over the world. Therefore, there is an urgent need to develop a sensitive and specific biosensor for identifying AAI. Aptamers as a powerful biorecognition element provide the most viable options for solving this problem. In this study, we used library-immobilized SELEX to isolate an AAI-specific aptamer with a KD value of 86 ± 13 nM. To verify the practicability of the selected aptamer, a label-free colorimetric aptasensor was designed. This aptasensor exhibited a low detection limit of 225 nM. Besides, it had been further applied for the determination of AAI in real samples and the recoveries ranged from 97.9% to 102.4%. In the future, AAI aptamer will provide a promising tool for safety evaluation in various fields of agriculture, food, and medication.

Ji H, Zhang G, Zhou X. Rapid simultaneous determination of thirteen aristolochic acids analogs in Aristolochiaceae plants by Ultra-High-Performance liquid Chromatography- tandem mass spectrometry in dynamic multiple reaction monitoring mode. J Chromatogr B Analyt Technol Biomed Life Sci 2023; 1225:123753. [PMID: 37216764 DOI: 10.1016/j.jchromb.2023.123753] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Revised: 05/08/2023] [Accepted: 05/11/2023] [Indexed: 05/24/2023]
Abstract
Asarum and Aristolochia are two large genera of Aristolochiaceae plants containing typical toxicant aristolochic acid analogs(AAAs), AAAs can be deemed as toxicity markers of Aristolochiaceae plants. Based on the least AAAs in dry roots and rhizomes of Asarum heterotropoides, Asarum sieboldii Miq and Asarum sieboldii var, all of which are enrolled in the Chinese pharmacopeia up to now. AAAs distribution in Aristolochiaceae plants, especially Asarum L. plants, is still obscure and controversial due to few AAAs measured, unverified species of Asarum, and complicated pretreatment in analytical samples making the results more challenging to reproduce. In the present study, a simple ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method in dynamic multiple reaction monitoring mode for simultaneous determination of thirteen AAAs was developed for evaluating the distribution of toxicity phytochemicals in Aristolochiaceae plants. The sample was prepared by extracting Asarum and Aristolochia powder with methanol, and the supernatant was analyzed using the Agilent 6410 system on an ACQUITY UPLC HSS PFP column with gradient elution of water and acetonitrile, containing 1% v/v formic acid (FA) each, at a flow rate of 0.3 mL/min. The chromatographic condition provided good peak shape and resolution. The method was linear over the specific ranges with the coefficient of determination (R2) > 0.990. Satisfactory intra- and inter-day precisions were achieved with RSD less than 9.79%, and the average recovery factors obtained were in the range of 88.50%~105.49%%. The proposed method was successfully applied for simultaneous quantification of the 13 AAAs in 19 samples from 5 Aristolochiaceae species, especially three Asarum L. species enrolled in the Chinese Pharmacopoeia. Except Asarum heterotropoides, the results supported that the Chinese Pharmacopoeia (2020 Edition) adopting the root with rhizome as medicinal parts of Herba Asari instead of the whole herb for drug safety by providing scientific data.

The Ginsenoside Rg 1 Rescues Mitochondrial Disorders in Aristolochic Acid-Induced Nephropathic Mice. Life (Basel) 2021; 11:life11101018. [PMID: 34685389 PMCID: PMC8539135 DOI: 10.3390/life11101018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 09/08/2021] [Accepted: 09/20/2021] [Indexed: 01/15/2023] Open
Abstract
Chronic exposure to aristolochic acid (AA) leads to renal interstitial fibrosis and nephropathy. In this study, we aimed to investigate the renoprotective effects of Panax ginseng extract (GE) and ginsenoside saponin (GS) on AA-induced nephropathy (AAN) in mice. Eighty female C3H/He mice were randomly divided into eight groups, including normal; AA (3 μg/mL for 56 days); AA with GE (125, 250, or 500 mg/kg/d for 14 days); and AA with important GE ingredients, Rg1, Rb1, or Rd (5 mg/kg/d for 14 days). Compared with the AA group, renal injuries were significantly decreased in the GE (250 mg/kg/d), Rb1, and Rg1 treatment groups. Rg1 exhibited the best renoprotection among all GS-treated groups. There were 24 peaks significantly altered among normal, AA, and AA + Rg1 groups, and four mitochondrial proteins were identified, including acyl-CoA synthetase medium-chain family member 2, upregulated during skeletal muscle growth 5 (Usmg5), mitochondrial aconitase 2 (ACO2), and cytochrome c oxidase subunit Va preprotein (COX5a). We demonstrated for the first time that the AAN mechanism and renoprotective effects of Rg1 are associated with expression of mitochondrial proteins, especially ACO2, Usmg5, and COX5a.
