Potential Hepatoprotective Effect of Matricaria Pubescens on High-Fat Diet-Induced Non-Alcoholic Fatty Liver Disease in Rats.

This study aimed to identify the phytochemical compounds of Matricaria pubescens by LC-MS/MS and evaluate the potential protective effect of its supplementation in high-fat diet (HFD)-induced non-alcoholic fatty liver disease (NAFLD) in adult rats through modulation of oxidative stress and histopathological changes. Twenty-four male rats were randomly divided into four groups. The first group served as control and received the standard diet. The second group (HFD) received a high-fat diet only (30 % of sheep fat). The third group's (control+MP) animals received a standard diet supplemented with 5 % M. pubescens (w/w). The fourth group (HFD+MP) received a high-fat diet supplemented with 5 % M. pubescens for 16 weeks. LC-MS/MS analysis showed that M. pubescens contains many phytochemical compounds. It was observed that the ethanolic extract of M. pubescens has a higher phenolic content than the aqueous extract. The supplementation of M. pubescens (5 % w/w) to HFD rats decreased significantly (p<0.01) body weight, liver and epididymal adipose tissue relative weights, glycemia, triglycerides (TG), insulin resistance, liver markers, TNF-α, malondialdehyde (MDA), protein carbonyl (PCO), advanced oxidation protein products (AOPP) level, and increased reduced glutathione (GSH) level, glutathione peroxidase (GPx), glutathione-S-transferase (GST), superoxide dismutase (SOD), and catalase activities as well as ameliorated histological alterations through the reduction hepatic lipid deposition and adipocytes hypertrophy compared to the HFD group. We conclude that M. pubescens powder may be effective for correcting hyperglycemia, hypertriglyceridemia, insulin resistance, and liver markers while decreasing inflammation and oxidative stress in the liver of high-fat diet-fed rats.

Study of the mineral contents of Matricaria pubescens and Brocchia cinerea from Algeria.

Two species of plants commonly used for mainly their therapeutic values and available in some herbalists shops, namely: Brocchia cinerea and Matricaria pubescens that both belong to asteraceae family, and encountered mainly in the Algerian desert, have drawn attention in the scope of assessing their mineral contents, in fact minerals play an important role in the plant homeostasis and metabolism, on the other hand they may influence the health conditions mainly due to toxicity, and also the benefits that the plant consumer could have, the current study aimed to assess the contents of Al, Cd, Cr, Cu, Fe, Hg, Ni, Pb, Zn, As, Na, K, Mg, P, S and SI, beside comparing the obtained results to other similar studies, the aerial parts of the plants are collected from several sites then mineralized and analyzed using ICP-AES and AAS, high levels of Na, K and Mg have been noted, on the other hands levels of metals were noted to be overall marginal, except for Al and Hg for the sample of Brocchia cinerea from El oued, the levels of As also seemed to be high in all the samples, inversely to the levels of S and P which seemed lower than those noted for other plants in paralleled studies, while that similar results were found for Zn, Fe, the chemical and geologic features of the soils may be the influencing factor. Additionally the current study may put first milestone for the establishment of national guidelines regarding the mineral contents of medicinal plants.

Antidyslipidemic and Antioxidant Activities of Matricaria pubescens (Desf.) Shultz. in Streptozotocin-Induced Diabetic Rats.

AIMS: The study aimed to evaluate the antihyperlipidemic and antioxidant activities of Matricaria pubescens. BACKGROUND: Matricaria pubescens (Desf.) Shultz belongs to Asteraceae family and it is commonly used traditionally for handling diabetes mellitus. OBJECTIVE: The objective of this study was to assess the antioxidant activity of Matricaria pubescens (Desf.) Shultz and its effect on lipid and lipoprotein profile in normal and streptozotocin-induced diabetic rats. METHODS: The effect of repeated (7 days of treatment) oral administration of the aqueous extracts of aerial part of Matricaria pubescens (MPAE) at a dose of 40 mg/kg on lipid and lipoprotein profile was examined in normal and streptozotocin-induced diabetic rats. Furthermore, a preliminary phytochemical screening and the quantification of phenolic, flavonoid and tannin contents as well as the antioxidant activity using two methods (FRAP and ABTS) were carried out. RESULTS: MPAE demonstrated a potent antidyslipidemic effect in diabetic rats by reducing serum levels of triglycerides, total cholesterol and Low-Density Lipoprotein (LDL). In addition, the results showed that the extract is rich in several phytochemical compounds and revealed an important antioxidant activity. CONCLUSION: In summary, this study proved that Matricaria pubescens (Desf.) Shultz. has a favorable effect on diabetic dyslipidemia.

Antihyperglycemic Potential of Matricaria pubescens (Desf.) Schultz. in Streptozotocin-induced Diabetic Rats.

AIMS: The study aimed to investigate the antihyperglycemic activity of Matricaria pubescens. BACKGROUND: Matricaria pubescens (Def). Shultz (Asteraceae) is commonly used traditionally for the treatment of diabetes in Morocco. OBJECTIVE: The present investigation aimed to assess the antihyperglycemic and antioxidant effects of the aqueous extract of the aerial part of Matricaria pubescens (M. pubescens). METHODS: The effect of a single and repeated oral administration of the aqueous extract of aerial part of M. pubescens (AEAPMP) at a dose of 40 mg/kg on glucose was examined in normal and streptozotocin-induced diabetic rats. Additionally, histopathological examination of the pancreas and liver was carried out according to the Hematoxylin-Eosin method. The antioxidant activity was performed using the DPPH assay. RESULTS: The results showed that the aqueous extract of M. pubescens (AEAPMP) exhibited a significant lowering activity on blood glucose levels in STZ-induced diabetic rats. In addition, AEAPMP ameliorated the histopathological tissues of the liver and pancreas. Furthermore, in vitro antioxidant activity of AEAPMP has been shown. CONCLUSION: In conclusion, this study demonstrates that M. pubescens possesses a beneficial effect against hyperglycemia associated with diabetes.
