Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.ABSTRACT Recirculating aquaculture system (RAS) is a promising strategy for economically and environmentally sustainable fish farming. Unfortunately, microorganisms in an RAS may produce off‐flavours that accumulate in fish flesh and reduce consumer attraction for aquaculture‐produced fish. Traditionally, geosmin (GSM) and 2‐methylisoborneol (MIB), the

Chemical constituents from Wedelia prostrata and their cytotoxicity activity [PDF]
, 2016 卤地菊（Wedeliaprostrata（Hook.etArn.）Hemsl.）为菊科蟛蜞菊属植物。对蟛蜞菊属植物研究调查表明，其主要含有二萜，倍半萜，黄酮和有机酸等化学成分。二萜尤其是对映-贝壳杉二萜类是蟛蜞菊属植物的主要活性成分，具有抗菌、抗病毒、抗氧化、抗癌、抗血管生成等生物活性。 本文首先用石油醚、乙酸乙酯、正丁醇三种不同极性的溶剂依次对卤地菊的乙醇提取物进行萃取，初步得到三个萃取部位，对卤地菊石油醚部位进行系统的化学成分研究，采用硅胶柱层析、聚酰胺柱层析、葡聚糖凝胶柱层析 ...
