Sugarcane bagasse, is one of the largest agriculture residues in the world and its chemical composition is interesting for several areas. Among one of the lipid components was found phytosterols. These are structurally and functionally similar to cholesterol, they are contributing to the reduction of cholesterol in the blood when consumed. Phytosterols were extracted with supercritical CO₂ from sugarcane bagasse. In this work was evaluated the effect of temperature (40–80 °C), flowrate (6–10 ml min⁻¹), pressure (200–400 bar) and co-solvent (0–10% ethanol) on extraction yield and phytosterols (β-sitosterol, campesterol and stigmasterol) concentration. The addition of co-solvent improves total phytosterols concentration at low pressure, but has no effect at high pressure. At optimal extraction conditions the yield was 0.92% and 0.300 mg total phytosterol g⁻¹ dry material. The extract obtained presented a lipidic composition with possible cardiovascular health benefits due to phytosterols, policosanols and unsaturated fatty acids found.

甘蔗渣是世界上最大的农业残留物之一，它的化学成分在几个领域都很有趣。在脂质成分之一中发现了植物甾醇。这些在结构和功能上与胆固醇相似，食用时有助于降低血液中的胆固醇。用超临界 CO ₂从甘蔗渣中提取植物甾醇。在这项工作中评估了温度 (40–80 °C)、流量 (6–10 ml min ^-1)、压力（200-400 巴）和共溶剂（0-10% 乙醇）对提取率和植物甾醇（β-谷甾醇、菜油甾醇和豆甾醇）浓度的影响。共溶剂的加入在低压下提高了总植物甾醇浓度，但在高压下没有影响。在最佳提取条件下，产率为0.92%和0.300mg总植物甾醇g ^-1干物质。由于发现了植物甾醇、多二十烷醇和不饱和脂肪酸，所获得的提取物呈现出具有可能对心血管健康有益的脂质成分。
