Camphor Tree Seed Kernel Oil Reduces Body Fat Deposition and Improves Blood Lipids in Rats

Abstract

The total and positional fatty acid composition in camphor tree (Cinnamomum camphora) seed kernel oil (CKO) were analyzed, and for the first time, the effect of CKO on body fat deposition and blood lipids in rats was studied. The major fatty acids in CKO were determined to be decanoic acid (C10:0, 51.49%) and dodecanoic acid (C12:0, 40.08%), and uniformly distributed at Sn-1, 3, and Sn-2 positions in triglyceride (TG). Rats were randomly divided into control, CKO, lard, and soybean oil groups. At the end of the experiment, levels of blood lipids and the fats of abdomen in the rats were measured. The main organ were weighted and used for the histological examination. The results showed that body weight and fat deposition in CKO group were significantly lower than the lard and soybean groups. Moderate consumption of CKO was found to improve the levels of blood TG and low density lipoprotein cholesterol.

Cinnamomum camphora Seed Kernel Oil Ameliorates Oxidative Stress and Inflammation in Diet‐Induced Obese Rats

“…Lard and soybean oil were purchased from a local supermarket. The components and distribution of fatty acids in CCSKO, lard, and soybean oil were reported previously (Fu and others ).…”

“…Our previous studies have shown that CCSKO reduced body fat deposition and improved blood lipid in both healthy and obese rats than intake equivalent amount of lard or soybean oil (Fu and others ; our unpublished data). Based on these previous findings, we hypothesized that CCSKO may ameliorate oxidative stress and inflammation in HFD‐induced obese rats.…”

“…Medium‐chain fatty acids (MCFAs) naturally occur as medium‐chain triglycerides (MCTs) with a low content in milk fat and other lipid fractionation from various feed materials (such as coconut and palm oils) (Marten and others ; Zentek and others ). Fatty acids from Cinnamomum camphora (commonly known as camphor tree) seed kernel oil (CCSKO) were found to contain more than 90% MCFAs, including capric acid (51.49%) and lauric acid (40.08%) (Zeng and others ; Zhao and others ; Fu and others ).…”

Effects of Liquid Phase Nano Titanium Dioxide (TiO2) on Seed Germination and Seedling Growth of Camphor Tree

“…The trunk and fruit can be used for medicine, and the medicine made from roots is called Tu Chen Xiang, which has the effects of promoting qi, promoting blood to reduce stasi, and removing arthralgia caused by wind, moisture or cold temperatures [ 2 ]. The latest research shows that camphor tree oil also has the function of reducing visceral fat and improving blood lipids [ 3 ]. Based on the above characteristics, the camphor tree was selected as the city tree of Loudi City, Hunan Province in 2004.…”

Mutagenesis and characterization of a Bacillus amyloliquefaciens strain for Cinnamomum camphora seed kernel oil extraction by aqueous enzymatic method

“…The content of medium chain fatty acid triglyceride (MCT) in Cinnamomum camphora seed kernel oil (CCSKO) was high (MCT > 94%), and MCT was reported to reduce the consumption and subsequent weight gain of animals (Mumme and Stonehouse 2015; Ferreira et al 2013; Wang et al 2016) and improve blood lipid and glucose levels (Page et al 2009; Fu et al 2015). There has been a growing interest in CCSKO and its extraction.…”
