Abstract

Diabetes mellitus can increase oxidative stress and damage cells. Noni fruit has antibacterial, antifungal, antitumor, analgesic, hypotensive, and anti-inflammatory benefits, can boost immunity, and has antioxidant content. Noni contains phenolic compounds (anthraquinones, acuities, asperulosides, and scopoletin), organic acids (capric and caprylic acids), and alkaloids (xeronine). The effect of noni ethanol extract can significantly reduce blood glucose (P<0.05) of the T2 group (177.00±137.78) and T3 (159.40±86.53) when compared to the C+ group (511.00±131.45). The T1 group (387.40±170.06) had no significant difference (P>0.05) when compared to the C+ group (511.00±131.45), but there was a decrease in the average yield at T1 (387.40±170.06). Serum malondialdehyde (MDA) examination showed a significant decrease (p<0.05) in T1 (1188.32±93.41), while in T2 (1385.35±38.65) and T3 (1460.32±42.51) was not significant (p<0.05). Examination of serum glutathione peroxidase (GPX) showed a significant decrease in T1 (119.97±37.45), there was a decrease in GPX levels, while in the T2 group (236.14±6.05) and T3 (185.24±43.07), there was no decrease. Noni ethanol extract can lower blood glucose levels, reduce Malondialdehyde levels, and prevent increased activity of the enzyme glutathione peroxidase. Flavonoid compounds in noni ethanol extract can avoid increased blood glucose and reduce free radicals formed due to hyperglycemia conditions.

Abstract

Cardiovascular disease (CVD) is a disease that causes death in the world. Behavioral risk factors are crucial in dealing with CVD disease. High levels of cholesterol in the blood are associated with hypercholesterolemia. It can increase the risk of CVD disease. The HMG-CoA reductase enzyme is an enzyme that plays a role in cholesterol synthesis. It will convert the HMG-CoA compound into the mevalonate. Inhibition of this enzyme can reduce cholesterol synthesis because it inhibits the formation of mevalonate, which is the initial stage of cholesterol synthesis. Herbal compounds are compounds produced by plants. It has good benefits for the body. Flavonoid compounds can be beneficial for health. Molecular docking is a method used to determine the binding affinity and interaction values ​​of the enzyme protein interaction with the ligand to be bound. The results of Apigenin binding affinity values is -7.7 kcal/mol, Luteolin is -8 kcal/mol, Quercetin is -8.2 kcal/mol, Kaempferol is -7.4 kcal/mol, Phloretin is -6.8 kcal/mol, Chalconaringenin is -6.9 kcal/mol, Cyanidin is -7.9 kcal/mol, Delphinidin is -7.8 kcal/mol, Hesperetin is -7.7 kcal/mol, Narigenin is -7.8 kcal/mol, Daidzein is -6.8 kcal/mol, Genistein is -7 kcal/mol, Rutin is -9.2 kcal/mol, Taxifolin is -8 kcal /mol, Diosmetin is -7.6 kcal/mol, and its native ligand Rosuvastatin is -8.5 kcal/mol. Flavonoid derivative compounds can bind to the HMG-CoA reductase enzyme. They can be candidates for antihyperlipidemia drugs.
