Macroalgae are one of potential sources for carotenoids, such as fucoxanthin, which are consumed by humans and animals. This carotenoid has been applied in both the pharmaceutical and food industries. In this study, extraction of fucoxanthin from wet brown seaweed Undaria pinnatifida (water content was 93.2%) was carried out with a simple method using liquefied dimethyl ether (DME) as an extractant in semi-continuous flow-type system. The extraction temperature and absolute pressure were 25 °C and 0.59 MPa, respectively. The liquefied DME was passed through the extractor that filled by U. pinnatifida at different time intervals. The time of experiment was only 43 min. The amount of fucoxanthin could approach to 390 μg/g dry of wet U. pinnatifida when the amount of DME used was 286 g. Compared with ethanol Soxhlet and supercritical CO₂ extraction, which includes drying and cell disruption, the result was quite high. Thus, DME extraction process appears to be a good method for fucoxanthin recovery from U. pinnatifida with improved yields.
大型海藻是类胡萝卜素的潜在来源之一，如岩藻黄质，人类和动物均可食用。这种类胡萝卜素已应用于制药和食品工业。在本研究中，采用简单方法，以液化二甲醚（DME）为萃取剂，在半连续流动系统中从湿褐藻裙带菜（含水量为93.2%）中提取岩藻黄质。萃取温度和绝对压力分别为25℃和0.59MPa。液化DME在不同时间间隔通过装有裙带菜的萃取器。实验时间仅为43分钟。当使用286g DME时，岩藻黄质的含量可达390μg/g湿裙带菜干重。与包括干燥和细胞破碎的乙醇索氏提取法和超临界CO₂萃取法相比，该结果相当高。因此，DME萃取工艺似乎是从裙带菜中回收岩藻黄质并提高产量的良好方法。
