The Cassia auriculata herb has been traditionally used in India for medicinal purposes to treat hyperglycemia, diabetes, rheumatism, asthma, and skin diseases. In the present study, ethanolic extract of Cassia auriculata flower (Et-CAF) depicted anti-hyperlipidemic effect in the budding yeast cells. The hyperlipidemic conditions were induced in the yeast cells with oleic acid which showed an increase in triacylglycerol (TAG) and sterol esters (SE), and was supported by the mRNA expression of LRO1 and DGA1 (involved in TAG formation); as well as ARE1 and ARE2 (involved in SE formation). The anti-hyperlipidemic effect by the Et-CAF was compared with the commercial drug Atorvastatin. The lipid droplets were increased in the hyperlipidemic yeast cell that was observed under the confocal microscope with BODIPY staining; Atorvastatin and Et-CAF reduced the lipid droplets. This study revealed that the anti-hyperlipidemic effect in Et-CAF has gained importance and might be used to fill the gap created by the allopathic drugs.
