Abstract

Asiatic acid is a triterpenoid isolated from Centella asiatica. The present study aimed to investigate whether asiatic acid could lessen the metabolic, cardiovascular complications in rats with metabolic syndrome (MS) induced by a high-carbohydrate, high-fat (HCHF) diet. Male Sprague-Dawley rats were fed with HCHF diet with 15% fructose in drinking water for 12 weeks to induce MS. MS rats were treated with asiatic acid (10 or 20 mg/kg/day) or vehicle for a further three weeks. MS rats had an impairment of oral glucose tolerance, increases in fasting blood glucose, serum insulin, total cholesterol, triglycerides, mean arterial blood pressure, heart rate, and hindlimb vascular resistance; these were related to the augmentation of vascular superoxide anion production, plasma malondialdehyde and tumor necrosis factor-alpha (TNF-α) levels (p<0.05). Plasma nitrate and nitrite (NOx) were markedly high with upregulation of inducible nitric oxide synthase (iNOS) expression, but dowregulation of endothelial nitric oxide synthase (eNOS) expression (p<0.05). Asiatic acid significantly improved insulin sensitivity, lipid profiles, hemodynamic parameters, oxidative stress markers, plasma TNF-α, NOx, and recovered abnormality of eNOS/iNOS expressions in MS rats (p<0.05). In conclusion, asiatic acid improved metabolic, hemodynamic abnormalities in MS rats that could be associated with its antioxidant, anti-inflammatory effects and recovering regulation of eNOS/iNOS expression.

  • C. asiatica has an anti-inflammatory effect observed by reduction in IL-1β, IL-6, TNFα, PGE2, and COX-2.

    “C. asiatica has shown an anti-inflammatory effect observed by the reduction in Interleukin-1β (IL-1β), Interleukin-6 (IL-6) and Tumour Necrosis Factor α (TNFα) [33,36,37], as well as prostaglandin E2 (PGE2) [36,38], and cyclooxygenase-2 (COX-2) [39].”

    From A systematic review of the effect of Centella asiatica on wound healing (2022) · cites this paper as [37]

    Results §3.5 reports reduced plasma TNF-α after asiatic acid treatment in metabolic-syndrome rats. The Discussion reports reductions in IL-1β, IL-6, and COX-2 from other asiatic-acid studies; PGE2 appears only in the title of a cited study in the References. The source concerns isolated asiatic acid, not C. asiatica as a whole, and does not itself report reductions in all five markers. (LLM, conf=0.85)

  • This enhancement might result from the anti-inflammatory effect of C. asiatica due to reduction in IL-1β, IL-6, TNFα, PGE2, and COX-2.

    “This might result from the anti-inflammatory effect caused by C. asiatica due to the reduction in IL-1β, IL-6 and TNFα [33,36,37], as well as prostaglandin E2 (PGE2) [36,38] and cyclooxygenase-2 (COX-2) [39].”

    From A systematic review of the effect of Centella asiatica on wound healing (2022) · cites this paper as [37]

    The Discussion reports reduced TNF-α in rats treated with asiatic acid and describes prior studies reporting reductions in IL-1β and IL-6. The source studies asiatic acid isolated from C. asiatica, not C. asiatica itself. In the printed sentence, this citation supports the cytokine portion; PGE2 and COX-2 have separate citations. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
