Lipid-lowering effect

The fat-soluble part of Alisolide has obvious cholesterol-lowering effect and anti-atherosclerotic effect on rabbits with experimental hypercholesterolemia, and the isolated Alisolide A, B, and Alisolide A, B, and C acetic esters, in addition to the Alisolide B, have significant cholesterol-lowering effect. The content of 0.1% added to the feed of experimental hyperlipidemia rats, can make the blood cholesterol decreased by more than 50%, of which the effect of Alisol A-24-acetate is the strongest. The ethanol extract and ethyl acetate extract of the ethanol extract of Alisol have hypolipidemic effects on experimental hypercholesterolemic rabbits and rats.

Effects on the cardiovascular system

Zelodea extract administered intravenously to dogs and rabbits had a mild hypotensive effect and lasted for about 30 minutes or so. The antihypertensive effect of zelda morinol on various experimental animals was mild and did not significantly affect plasma renin and ACE activity or aldosterone levels. Alcoholic extracts of zeylanol had a slow relaxing effect on adrenaline-induced conditioned contraction of isolated rabbit aorta in vitro. Zelenolol inhibited the contraction of rabbit aortic strips induced by angiotensin in a dose-dependent manner. Zelenamol was seen to decrease cardiac output and heart rate and left ventricular pressure with the isolated heart perfusion technique, but increased coronary flow.
