Synadenium grantii extracts were obtained by employing two different extraction techniques: supercritical CO₂ with ethanol as solvent (scCO₂+EtOH) and Soxhlet with different solvents. Extractions were evaluated according to antioxidant capacity, extract compositions, and overall extraction yields, which increased with solvent polarity. For Soxhlet extractions, the highest extraction yield was obtained with water as the solvent and the lowest with hexane. In extraction using scCO₂+EtOH, the addition of ethanol increased the extraction yield and kinetic parameters due to the increase in solvent polarity. The IC₅₀ result demonstrated that extracts obtained with polar solvents presented higher antioxidant capacity in comparison to non-polar solvents. For scCO₂+EtOH extractions, the result with higher antioxidant capacity was obtained using ethanol to solids mass ratio of 1:1. The most important compounds identified in S. grantii extracts by mass spectrometry were euphol, carvacrol, betulin aldehyde, and friedelan-3-one, which have great potential applications in cosmetics, pharmaceuticals, and food industries.

通过使用两种不同的提取技术，可以得到Grantade的Synadenium提取物：超临界CO ₂以乙醇为溶剂（scCO ₂ + EtOH）和索氏萃取法使用不同的溶剂。根据抗氧化剂容量，提取物成分和总提取率（随溶剂极性增加而增加）评估提取率。对于索氏提取，以水为溶剂可获得最高的提取率，而以己烷为最低。在使用scCO ₂ + EtOH进行萃取中，由于溶剂极性的增加，乙醇的添加提高了萃取率和动力学参数。IC ₅₀结果表明，与非极性溶剂相比，使用极性溶剂获得的提取物具有更高的抗氧化能力。对于scCO ₂ + EtOH萃取，使用乙醇与固体的质量比为1：1可获得具有较高抗氧化能力的结果。在质谱法中鉴定出的格兰特酵母提取物中最重要的化合物是紫杉醇，香芹酚，桦木素醛和Friedelan-3-one，它们在化妆品，制药和食品工业中具有巨大的潜在应用。
