Zusammenfassung:Phytochemicals are the bioactive components that contribute to the prevention of cardiovascular and other degenerative diseases. Inhibition of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase would be an effective means of lowering plasma cholesterol in humans. The present study explores the HMG CoA reductase inhibitory effect of extracts from leaves of Morus indica varieties, M5, V1, and S36, compared with the statin, using an ex vivo method. The assay is based on the stoichiometric formation of coenzyme A during the reduction of microsomal HMG CoA to mevalonate. Dechlorophyllised extract of three varieties was studied at 300 µg. The coenzyme A released at the end of assay in control (100.31 nmoles) and statins (94.46 nm) was higher than the dechlorphyllised extracts of the samples. The coenzyme A released during the reduction of HMG CoA to mevalonate in dechlorophyllised extracts of the samples was as follows: S36 < M5 < V1. The results indicated that the samples were highly effective in inhibiting the enzyme compared to statins (standard drug). The results indicate the role of Morus varieties extracts in modulating the cholesterol metabolism by inhibiting the activity of HMG CoA reductase. These results provide scope for designing in vivo animal studies to confirm their effect.
