Background: Type 2 diabetes mellitus is a prevalent systemic disease affecting an important proportion of the population worldwide. It has been suggested that excessive reactive oxygen species generation and therefore development of an oxidative stress status is a key factor leading to diabetic complications. Accordingly, it seems that medicinal plants can offer a wide range of new antidiabetic drugs.

Sulphated polysaccharide isolated from Sargassum vulgare: Characterization and hypolipidemic effects.

A sulphated polysaccharide from brown algae Sargassum vulgare (SVSP) was extracted and examined with respect to chemical, structural characterization and hypolipidemic effects. SVSP consisted mainly of sulphate and total sugars with low levels of lipids and proteins. Its structure was studied by nuclear magnetic resonance (RMN), gas chromatography-mass spectrometry (GC-MS), infra-red spectroscopic, differential scanning calorimetry and X-ray diffraction analysis.

The present study investigates the hypolipidemic effects of sulphated polysaccharide obtained from Codium fragile (CFSP) in induced obese rats (HFD). The results showed an increase in body weight of HFD rats by 21.56% as compared to control normal rats.

Effects of Cymodocea nodosa extract on metabolic disorders and oxidative stress in alloxan-diabetic rats.

This new study aimed to evaluate for the first time the effect of Cymodocea nodosa extract (CNE) on α-amylase activity, hyperglycemia and diabetes complications in the alloxan-induced diabetic rats. The in vitro evaluation and oral administration of CNE to surviving diabetic rats inhibited key enzyme related to hyperglycemia as α-amylase, helped to protect the β cells of the rats from death and damage confirmed by oral glucose test tolerance (OGTT), which leads to decrease in blood glucose level by 49% as compared to untreated diabetic rats. The CNE also decreased the triglyceride, low density lipoprotein (LDL) cholesterol and total cholesterol rates in the plasma of diabetic rats by 46%, 35%, and 21%, respectively, and increased the high density lipoprotein (HDL) cholesterol level by 36%, which helped maintain the homeostasis of blood lipid.

Inhibition of key digestive enzymes related to hyperlipidemia and protection of liver-kidney functions by Cystoseira crinita sulphated polysaccharide in high-fat diet-fed rats.

The objective of this current study was to investigate the possible hyperlipidemic and antioxidative effects of Cystoseira crinita sulfated polysaccharide (CCSP) in rats fed with a high-fat diet, exhibited an inhibitory activity on pancreatic lipase in vitro. In vivo administration of this extract to HFD-rats lowered body weight and potentially inhibited key enzymes of lipid metabolism and absorption as lipase activity in both plasma and small intestine, which led to a notable decrease of blood LDL- cholesterol (LDL-Ch) and triglycerides (TG) levels, and an increase in HDL-cholesterol (HDL-Ch) levels in HFD-rats. CCSP was also observed to protect the liver-kidney functions efficiently, by decreasing of aspartate transaminase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH) and Creatine phosphokinase (CPK) activities and creatinine, albumin, T-bilirubin, uric acid, and urea rates in plasma.
