Urinary elimination of ecdysterone after consumption of quinoa alone and in combination with spinach. Arch Pharm (Weinheim) 2024; 357:e2300689. [PMID: 38400693 DOI: 10.1002/ardp.202300689] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 02/02/2024] [Accepted: 02/05/2024] [Indexed: 02/25/2024]
Abstract
The phytosteroid ecdysterone is classified as an anabolic agent and has been included on the monitoring list of the World Anti-Doping Agency since 2020. Therefore, the consumption of food rich in ecdysterone, such as quinoa and spinach, is the focus of a lively debate. Thus, the urinary excretion of ecdysterone and its metabolites in humans was investigated following quinoa consumption alone and in combination with spinach. Eight participants (four male and four female) were included, and they ingested 368 ± 61 g cooked quinoa alone and in combination with 809 ± 115 g spinach after a washout. Post-administration urines were analyzed by LC-MS/MS. After intake of both preparations, ecdysterone and two metabolites were excreted in the urine. The maximum concentration of ecdysterone ranged from 0.44 to 5.5 µg/mL after quinoa and from 0.34 to 4.1 µg/mL after quinoa with spinach. The total urinary excreted amount as parent drug plus metabolites was 2.61 ± 1.1% following quinoa intake and 1.7 ± 0.9% in combination with spinach. Significant differences were found in the total urinary excreted amount of ecdysterone, 14-deoxy-ecdysterone, and 14-deoxy-poststerone. Only small portions of ecdysterone from quinoa and the combination with spinach were excreted in the urine, suggesting that both quinoa and spinach are poor sources of ecdysterone in terms of bioavailability.

Abstract
The naturally occurring compounds ecdysterone and turkesterone, which are present in plants, including Rhaponticum carthamoides Willd. (Iljin), Spinacia oleracea L., Chenopodium quinoa Willd., and Ajuga turkestanica (Regel) Briq, are widely recognized due to their possible advantages for both general health and athletic performance. The current review investigates the beneficial biological effects of ecdysterone and turkesterone in nutrition, highlighting their roles not only in enhancing athletic performance but also in the management of various health problems. Plant-based diets, associated with various health benefits and environmental sustainability, often include sources rich in phytoecdysteroids. However, the therapeutic potential of phytoecdysteroid-rich extracts extends beyond sports nutrition, with promising applications in treating chronic fatigue, cardiovascular diseases, and neurodegenerative disorders.

Variation of Sequential Ligandrol (LGD-4033) Metabolite Levels in Routine Anti-Doping Urine Samples Detected with or without Other Xenobiotics. Molecules 2023; 28:6486. [PMID: 37764261 PMCID: PMC10535477 DOI: 10.3390/molecules28186486] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 08/24/2023] [Accepted: 09/04/2023] [Indexed: 09/29/2023] Open
Abstract
Ligandrol, also known as LGD-4033, belongs to the group of selective androgen receptor modulators (SARMs). Ligandrol was first included in the WADA Prohibited List in 2018. This work presents a method that allows for the detection and identification of ligandrol and its metabolite in athletes' urine and in dietary supplements by means of ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Samples were prepared according to an approach involving acid hydrolysis and double liquid-liquid extraction (LLE). Furthermore, due to the lack of reference material for ligandrol metabolites, the urine collected from the control excretion study was analyzed. The presented method is appropriate to monitor ligandrol and its metabolites. The samples collected for doping control purpose contained multiple metabolites, which may potentially rule out the hypothesis of ingesting a single 1 µg or 10 µg dose only. Another aspect to take into account is that ligandrol can be applied together with SARMs, steroids, and GHSs. This will also affect the substances' metabolism and elimination. It is also worth noting that dietary supplements may contain ligandrol as an official ingredient or as a contaminant. The described method may be usefully applied by other anti-doping or toxicological laboratories.

Abstract
The aim of our research was to perform a comprehensive study of ecdysterone (ECD)-containing dietary supplements (DSs). Two analytical methods were optimised according to the expected concentration of the target compounds: quantitation of ECD by liquid chromatography (LC) coupled to diode array detector (DAD), and limit test for 47 World Anti-Doping Agency prohibited by LC coupled with tandem mass spectrometer (MS/MS). For quantitation of ECD, the method was fully validated with outstanding performance characteristics (LOD: 35 µg·g−1, LOQ: 115 µg·g−1, CV% < 5%), resulting in significantly lower LOD and shorter runtime than published previously. For limit tests, a chromatographic method was developed to obtain excellent separation, while MS/MS parameters were optimised to allow the lowest possible reporting limit (RL: 0.6–10 ng·g−1 or mL−1). Twenty-one ecdysterone-containing DSs from ten brands were analysed. In all cases, the measured ECD content was much lower than labelled, and 20% of the samples contained a prohibited substance. The concentration of ecdysterone and contaminations varied randomly from batch to batch. The developed methods help to prevent the use of contaminated or useless DSs.

Abstract
Ecdysterone (crustecdysone; beta-ecdysone; 20-hydroxyecdysone) is a naturally occurring steroid hormone belonging to the ecdysteroid class. The presented study investigated the possible concentration range of ecdysterone in urine after consumption of various preparations of spinach, drinking tea (made from Rhapoiticum Carthamoides) and topical use of a cream containing Cyanotis arachnoides. It is very important to establish reference ranges reflecting concentrations compatible with dietary habits and common uses of care products. The data obtained in the research may be used in the interpretation of results of routine analyses. In addition, elimination time and observed concentrations provided by the studies conducted by the Polish Anti-Doping Laboratory can be used by WADA. In the case of spinach, peak elimination occurred within the first few hours, followed by a rapid decline. As for the other plants, instead of clear peak concentrations, gradual elimination was observed. Individual differences were observed between volunteers depending on route of administration. Differences in ecdysterone elimination following ingestion of spinach-based and other plant products were observed too. The highest observed ecdysterone concentration was related to the paste consumption, and it was 691 ng/ml. Finally, our findings were compared with the data collected for the samples routinely tested as part of the monitoring program. During 2.5 years, the presence of ecdysterone was confirmed in as many as 507 samples out of 11 191 total samples tested. The concentration range was very wide, from 1 ng/ml (which is the LOD for this method in the Polish Anti-Doping Laboratory) to over 2000 ng/ml.
