采用叶片浸渍法和分光光度法研究了大叶丁香(Eugenia caryophyllata Thunb)丙酮提取物对皮氏叶螨(Tetranychus piercei McGrvgor)的毒力及其代谢酶活性的影响。
- An insecticidal component, 1B-4 was isolated from the acetone extract of the mycelium of IB strain by bioassay-guided. The molecule structure of 1B-4 was determined by IR and NMR as a kind of fatty acid.
- The results show that acetone extracts and concentrated water extracts of all the above green teas markedly inhibit the mutagenicity of AFB1 and B(a)P.
