Abstract

Flour from the young shoots of the palmyrah palm (Borassus flabellifer) was tested in Salmonella typhimurium, strains TA98 and TA100 (Ames test) and Escherichia coli, strains WP2, WP2uvrA, CM881 and CM891. The flour was tested in two forms: boiled and raw. Both forms showed dose related mutagenic responses in the basepair substitution sensitive strains TA100 and Escherichia coli WP2uvrA, CM881 and CM891. The flour from boiled palmyrah shoots exerted a somewhat stronger mutagenic effect on TA100 than flour from the raw shoots. This investigation adds mutagenicity to the wide range of biological effects of palmyrah flour already described (induction of malignant lymphomas, immunosuppression, neurotoxicity and clastogenicity).

摘要

对扇叶棕榈（Borassus flabellifer）嫩梢磨制的面粉进行了鼠伤寒沙门氏菌TA98和TA100菌株（艾姆斯试验）以及大肠杆菌WP2、WP2uvrA、CM881和CM891菌株的测试。面粉以两种形式进行测试：煮熟的和生的。两种形式在碱基对置换敏感菌株TA100以及大肠杆菌WP2uvrA、CM881和CM891中均呈现出剂量相关的诱变反应。煮熟的扇叶棕榈嫩梢磨制的面粉对TA100的诱变作用略强于生嫩梢磨制的面粉。这项研究在扇叶棕榈面粉已被描述的广泛生物学效应（诱导恶性淋巴瘤、免疫抑制、神经毒性和致断裂性）基础上又增加了致突变性。
