Virgin coconut oil (VCO) was used as co-extractant with supercritical carbon dioxide (scCO₂) extraction for obtaining xanthones from mangosteen pericarp (MP) without organic co-solvents. In each experiment, 120 g of dried MP that had median particle sizes of 0.85 mm was used. Extraction of MP with 40% VCO co-extractant using scCO₂ (1.08 kg/h) for 420 min at 430 bar and 70 °C gave α-mangostin (32.2 mg/g), γ-mangostin (7.2 mg/g), xanthones (28.2 mg/g) in extract and an extraction yield of 31%. The role of VCO is that it promotes dissolution of xanthones and mass transfer into the scCO₂ phase as elucidated with the Pardo-Castaño model. The Lentz equation was generalized in terms of (P, T, %VCO, ρ_CO2) to correlate all extraction curve data to within 7.4% and to estimate extraction yield crossover regions. Xanthones can be separated from mangosteen pericarp with VCO and scCO₂ extraction without organic co-solvents.

初榨椰子油（VCO）与超临界二氧化碳（scCO ₂）一起用作共萃取剂，用于从山竹果皮（MP）中获得没有有机助溶剂的黄酮。在每个实验中，使用具有中值粒度为0.85mm的120g干燥的MP。在430 bar和70°C下使用scCO ₂（1.08 kg / h）于420分钟内用40％VCO共萃取剂提取MP，得到α-芒果素（32.2 mg / g），γ-芒果素（7.2 mg / g），提取物中的氧杂蒽酮（28.2 mg / g）和提取产率为31％。如Pardo-Castaño模型所阐明的，VCO的作用是促进氧杂蒽的溶解和质子转移到scCO ₂相中。Lentz方程用（P，Ť，％VCO，ρ _CO2）相关联的所有的提取曲线数据至7.4％的范围内，并估计提取率交叉区域。可以在不使用有机助溶剂的情况下，通过VCO和scCO ₂萃取从山竹果皮中分离出Xanthones 。
