摘要

采用方框-贝肯设计法研究了温度、压力和特定溶剂消耗量对鳞茎提取率的影响。压力对提取率的影响最大，其次是温度和特定溶剂消耗量（p ≤ 0.05）。萃取率与二氧化碳密度呈正相关（p ≤ 0.05）。扩散模型充分描述了累积萃取曲线，在选定的萃取条件下，萃取率最高。超临界（SC）萃取物对亚油酸氧化的抑制作用和对脂氧合酶的抑制作用均高于水乙醇萃取物。超临界萃取可用于从鳞茎中分离出具有功能价值的化合物。

Supercritical CO2 Extraction From Leptocarpha rivularis Stalks Using Box–Behnken Design

The effect of temperature, pressure, and specific solvent consumption on extraction yield from Leptocarpha rivularis stalks was studied using a Box–Behnken design. The effect of pressure on extraction yield was the most important, followed by temperature and specific solvent consumption (p ≤ 0.05). The extraction yield correlated (p ≤ 0.05) positively with the CO₂ density. A diffusion model adequately described the cumulative extraction curve with the highest yield at the selected extraction condition. The inhibition of linoleic acid oxidation and the inhibition of lipoxygenase enzyme were higher in the supercritical (SC) extract than in the hydroethanolic extract. SC extraction could be used to isolate compounds from L. rivularis stalks with functional value.
