Abstract:
Background: Portulaca grandiflora is a tiny, upright herb that contains a variety of
chemical components, including alkaloids, glycosides, mucilage, proteins, tannins, flavonoids,
saponins, polysaccharides, and triterpenoids possessing properties that may help with atherosclerosis.
The reported pharmacological properties of Portulaca grandiflora are antioxidant, antidiabetic,
antiasthmatic, antibacterial, antiulcer and anti-inflammatory properties.
Objectives: The yield of methanol extract is higher than that of ethanol and acetone, and its phytoconstituents,
like flavonoids and polyphenols, and has potent antioxidant properties. In order to
determine the effectiveness of Portulaca grandiflora methanol extract fraction against high-fat
diet (HFD)-induced hyperlipidemia, hemodynamic change, antioxidant levels, and vascular dysfunction
in rats, a study was carried out on a flavonoid-rich methanol extract fraction of the aerial
part of Portulaca grandiflora Hook.
Methods: This method involves a study of 30 days involving male Wistar rats (240–250 g) (n=5)
that were fed with an Ath diet. Study groups were divided into (i) The Control Group, (ii) the
Diseases Control Group, (iii) Disease + Standard drug (Atorvastatin 20mg/kg, orally, (iv) Disease
+ Test Extract dose 1 (Portulaca grandiflora 200 mg/kg orally), and (v) Disease + Test Extract
dose 2 (Portulaca grandiflora 400 mg/kg orally). Both the test drug Portulaca grandiflora
and the standard drug Atorvastatin were given orally for 30 days.
Results: At the end of the study, blood samples were taken to measure the serum lipid profile,
alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, and levels of oxidative
tissue stress. Hemodynamic parameters and aortic staining were performed. Portulaca grandiflora
treatment improved the lipid profile and considerably reduced oxidative stress levels.
Aortic staining examination revealed a marked reduction in atherosclerotic lesions.
Conclusion: These results revealed that Portulaca grandiflora is an effective treatment approach
in preventing atherosclerotic lesion progression, which is attributed to its protection against oxidative
stress and various enzymatic activities in the Atherogenic model.
