Hypotriglyceridaemic activity ofFicus carica leaves in experimental hypertriglyceridaemic rats

Abstract

A model of hypertriglyceridaemia in rats is described, which was used to investigate the hypolipidaemic effect of an intraperitoneal (i./p.) administration of a Ficus carica leaf decoction. Hypertriglyceridaemia was induced in rats following the protocol: a fasting period of 22 h, 2 h of oral (p.o.) administration of 20% emulsion of longchain triglycerides (LCT emulsion), both repeated once. The plasma triglyceride and total cholesterol levels obtained 2 h after the protocol were 5.7 ± 2.5 mmol/L (p < 0.0001 vs basal levels) and 1.7 ± 0.3 mmol/L, respectively, n = 10. The new model was used to test the hypotriglyceridaemic effect of a single dose of Ficus carica (fig tree) leaf decoction administered i./p. (50 g dry wt/kg body wt). After the i.p. injection of serum saline (control group, n = 10) or Ficus carica extract (group A, n = 10), plasma triglyceride levels in the control group and group A were 5.9 ± 2.9 mmol/L and 5.5 ± 2.9 mmol/L just after the LCT emulsion protocol; 4.7 ± 2.7 mmol/L and 0.9 ± 0.4 mmol/L, p < 0.005, 60 min after the LCT protocol; and 3.6 ± 2.9 mmol/L and 1.0 ± 0.4 mmol/L, p < 0.05, 90 min after the LCT protocol. The plasma total cholesterol levels, which were not modified in our experimental model, showed no significant differences in relation to baseline levels in the presence or absence of Ficus carica treatment either. The clearly positive results suggest the presence in the fig leaf decoction of a compound or compounds that influence lipid catabolism. Copyright © 1999 John Wiley & Sons, Ltd.

Synthesis and <i>in vivo</i> anti-hyperlipidemic activity of novel n-benzoylphenyl-2-furamide derivatives in Wistar rats

“…Our results showed that the hyperlipidemia induced by Triton WR-1339 was significantly reduced by compounds 4b, 4c, and bezafibrate in comparison with the hyperlipidemic control group after 18 h. It was not surprising that the reduction in triglycerides levels of compounds 4b and 4c were significantly greater than the reduction in cholesterol levels; this could be explained by the significant elevation in plasma lipid profile following Triton WR-1339 administration which results mostly from the increase in VLDL (in which the triglycerides portion is several times greater than that of cholesterol) [23]. This result suggests that the compounds are able to restore, at least partially, the catabolism of lipoproteins.…”

Anti-hyperlipidemic Activity of Thieno - [2, 3-d] - Pyrimidin-4-(3H)-ones

“…The underlying mechanism of this activity is not elucidated by the present study. However, as hypothesised by many works [36] the restoration of catabolic metabolism of triglycerides could be due to an increased stimulation of the lipolytic activity of plasma lipoprotein lipase (LPL).…”

Antihyperlipidemic activity ofIchnocarpus frutescensin triton WR-1339-induced and high-fat diet animals

“…The hypolipidemic action of I. frutescens extract was markedly higher for Tg than for TC. The underlying mechanisms are not elucidated in this study; however, the restoration of catabolic metabolism of very-low-density lipoprotein could be due to an increased stimulation of the lipolytic activity of plasma lipoprotein lipase (Pérez et al, 1999).…”
