Comprehensive analysis of Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. fruits based on UPLC-MS/MS and GC-MS: A rapid qualitative analysis

Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. fruits (ESF), as a natural edible fruit, has long been popularized. However, few studies have conducted comprehensive chemical analyses of it. This study aimed to assess nonvolatile, volatile, and fatty oil components of ESF and to preliminarily explore the antioxidant activities. The qualitative and quantitative analyses of volatile and fatty oil components of ESF from 15 different regions were performed by the gas chromatography-mass spectrometry (GC-MS). Totally, 37 and 28 compounds were identified from volatile oil and fatty oil, respectively. The ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS/MS) was used to accurately detect 43 compounds of nonvolatile components. The volatile and fatty oil components and nonvolatile components of ESF were used as samples to determine the antioxidant activity of 2,2-diphenyl-1-picrylhydrazyl (DPPH) in vitro. The components of ESF had antioxidant activity, and the nonvolatile components had stronger antioxidant activity. The results revealed that the proposed method, which is of great significance for the screening of new active ingredients, is valuable for the identification of pharmaceutical component and further development of food industry.

Safety and efficacy of a feed additive consisting of a tincture derived from the roots of Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. (taiga root tincture) for use in dogs, cats and horses (FEFANA asbl)

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of a tincture from the roots of Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. (taiga root tincture) when used as a sensory additive in feed for dogs, cats and horses. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the additive is safe for dogs, cats and horses at the maximum proposed use level of 460.7, 489.5 and 140.7 mg/kg complete feed, respectively. The additive was considered safe for consumers when used at the proposed conditions of use in horses for meat production. The additive under assessment should be considered as irritant to skin and eyes, and as a skin and respiratory sensitiser. The use of the taiga root tincture as a flavour in feed for horses was not expected to pose a risk for the environment. Since the root of E. senticosus has flavouring properties and its function in feed would be essentially the same as that in food, no further demonstration of efficacy is considered necessary for the tincture under assessment.
