Comparative effects of peel extract from Nigerian grown citrus on body weight, liver weight and serum lipids in rats fed a high-fat diet

Abstract

The effects of ethanolic extracts of five different citrus peels on mean body and liver weight and serum lipid content were investigated in albino rats. Six groups (n=8 each) were fed with a high fat diet for seven days ad libitum before oral daily administration of the peel extracts of orange (OR), lemon (LE), lime (LI), tangerine (TA), grapefruit (GR) and synergistic combination of equal ratios (w/w), that is, (SY), respectively at a dose of 500 mg / kg body weight for 14 days. The positive control group received only the high fat diet (HFD), while the negative control group received only a standard diet (STD). The body weights of the animals were monitored every two days and the animals were sacrificed after the 7 th and 14 th days of or following the administration of the extracts. All the parameters increased in the positive control group (HFD) compared to the negative control (STD) group. Body and liver weights decreased in all treated groups, as well as serum cholesterol and triglycerides, which decreased significantly in SY and GR groups, p < 0.05. All extracts contained mainly flavonoids and alkaloids while the grapefruit peel extract contained additional saponins that could contribute to the reduction in both body weight and serum lipid content. Conclusively, peel extract from different types of Nigerian citrus which ordinarily serve as waste may synergistically be used to control and manage obesity and associated pathologies.

Ultrasound-Assisted Extraction of Polyphenols from Pomelo (Citrus Grandis Limonia Osbeck L.) Peel

“…This fact necessitates the recycling of these wastes. The pomelo peel includes two parts -the albedo (white color) and flavedo (green color) that have a high content of bioactive phenolic compounds, which provides health benefits such as antiinflammatory [2], body weight control [3] and anticancer [4] properties. The beneficial effects of polyphenols are mainly attributed to their antioxidant ISSN: 2734-9381 https://doi.org/10.51316/jst.153.etsd.2021.31.…”

Antimicrobial Activity and Phytochemical Screening of Citrus aurantifolia Leaves Ethanolic Extract

“…Cawan kemudian diinkubasi pada suhu 37 ± 2 ⁰C PENDAHULUAN JERUK nipis (Citrus aurantifolia S.) merupakan tanaman yang dimanfaatkan baik untuk bumbu masakan maupun sebagai obat tradisional (1) . Banyak penelitian telah menunjukkan bahwa berbagai bagian tanaman Citrus aurantifolia (daun, batang, akar, kulit kayu) dapat digunakan sebagai antipiretik, antiradang, antibakteri, antijamur, antidiabetik, antioksidan, antihipertensi, antilipidemik, atau penyakit kardiovaskular (2)(3)(4)(5)(6)(7)(8) . Jeruk nipis juga digunakan dalam industri makanan, obat-obatan, dan kosmetik karena khasiat dan aromanya.…”
