摘要
建立了从杜氏藻鲜藻中直接提取、纯化β－胡萝卜素及快速检测其含量的新方法，发现在十种（株）杜氏藻Ｄｕｎａｌｉｅｌｌａｂａｒｄａｕｉｌ中生成β－胡萝卜素的量最高，达藻干重的４．１９％，在最佳条件下可达１３％，经动物急性毒性实验测得小鼠对杜氏藻β－胡萝卜素的最大耐受量＞２４０ｍｇ·ｋｇ￣（－１）．
A new method has been used for extraction,purification and determination of thecontent level of β-carotene from the green alga Dunaliella. It has been found that D .bardauil can accu-mulate 4.19%β-carotene of its dried weight.The content of β-carotene is the highest level in the tenspecies(strains) of Dunaliella tested.Morever under a favourable condition,D. bardauil is able to pro-duce β-carotene as much as 13% of its dried weight.According to the tolerance determination,thetolerance for rats to the β-carotene extracted from Dunaliella was more than 240 mg·kg￣(-1).
