Microencapsulated curcumin from Curcuma longa modulates diet-induced hypercholesterolemia in Sprague Dawley rats

Abstract

Hypercholesterolemia is one of the major causes of cardiovascular ailments. The study has been conducted on the hypothesis that hypercholesterolemia can be modulated by microencapsulated curcumin due to its enhanced bioavailability. In this context, curcumin obtained from fresh rhizomes of Curcuma longa by conventional (CSE) and supercritical fluid (SFE) extractions, has been successfully microencapsulated using a mixture of gelatin and maltodextrin. The microencapsulated curcumin CSE&SFE, has been added as supplemented diet and has been resulted in maximum plasma concentration of curcumin at 100 min as 529.31 ± 8.73 and 405.23 ± 7.12 μg/mL, respectively compared to non-encapsulated turmeric powder used as control. During the bio evaluation trial, turmeric powder (3%), microencapsulated curcuminCSE (1%) and microencapsulated curcuminSFE (0.5%) were provided to designate rat groups categorized by normal; N1, N2, and N3 and hypercholesterolemic; H1, H2, and H3 conditions, respectively. The incorporation of microencapsulated curcuminSFE in the supplemented diet caused a reduction in serum cholesterol, low density lipoprotein (LDL) and triglycerides, athrogenic index (AI) and cardiac risk ration (CRR) as 5.42 and 12.81%, 7.25 and 15.42%, 3.17 and 9.38%, 15.38 and 29.28%, and 10.98 19.38% in normo- and hypercholesterolemic rat groups. Additionally, high-density lipoprotein (HDL) and anti-atherogenic index (AAI) indicated a significant increase in all treated rat groups. Conclusively, the inclusion of turmeric and curcumin microencapsulates in the dietary module has been proven effective to alleviate hyperlipidemia. Therefore, the present study is proven that curcumin absorption via the gastrointestinal tract and its stability toward metabolization in the body increased via microencapsulation using maltodextrin and gelatin. Microencapsulated curcumin reaches the target site via oral administration because of sufficient gastrointestinal residence period and stability in the digestive tract.

Unveiling the Chemistry of Citrus Peel: Insights into Nutraceutical Potential and Therapeutic Applications

“…Basically, two reaction processes are involved by virtue of that the citrus peel bioactive ingredient in the resultant extract triggers a protection mechanism against oxidation [134]. First, the single electron transfer method depends on the reduction of oxidation compounds like carbonyls, metals, and radicals [135].…”

Serum VCAM-1 reduction by phytosomal curcumin formulation in rats on a high-fat diet

“…Curcumin has been reported to have many health and therapeutic properties, and previous evidence has shown that it has strong anti-inflammatory and antioxidant properties (Uchio et al, 2021;Peng et al, 2021;Fuloria et al, 2022). Different animal studies have established curcumin's antiatherosclerotic effect, its effect in alleviating hyperlipidemia (Panahi, Ahmadi, Teymouri, Johnston, & Sahebkar, 2018;Ashraf et al, 2022), and on the expression of CAMs levels (Um et al, 2014;Pradana et al, 2019). These studies relied on different delivery curcumin formulations including solid dispersions, complexation with cyclodextrins, co-administration with piperine, as nano-particles/emulsions, and as microencapsulation/emulsions.…”

“…On the other hand, the encapsulation of curcumin using carboxymethylcellulose and maltodextrin has been reported [13][14][15][16][17]. It was reported that curcumin encapsulation on carboxymethyl cellulosemontmorillonite clay nanocomposite could enhance the stability and solubility of curcumin in water [18].…”
