281 double crossover mutants were examined by fermentation experiments and hplc analysis for production of polyketides. besides avermectin b1a and b2a, a new compound ( about l ~ 4ug / ml ) which showed a retention time and fragmentation patterns identical to those of the authentic sample of 22, 23 - dihydroavermectin bla by hplc and lc / ms analysis were detected in culture extracts of 27 isolates
在篩選的281個雙交換突變株中，有27株除了產生阿維菌素b1a和b2a ，還產生一個新組分，經hplc和lc ms分析，證實該組分為c - 22 ， 23雙氫阿維菌素b1a （即伊維菌素b1a ） 。 -
After reference solution has been formulated and sensitivity has been adjusted and tested according to above mentioned method ( 3 ), take appropriate amount of test sample solution and reference solution, blend samples separately ; unless otherwise specified, recording time of the former should be 2 times of retention time of chromatographic peak of main component, measure peak area of each impurity on the chromatograph chart of test sample solution, and compare with peak area of main components of reference solution, then calculate content of each impurity accordingly
同上述（ 3 ）法配製對照溶液並調節檢測靈敏度后，取供試品溶液和對照溶液適且，分別迸樣，前者的記錄時間，除另有規定外，應為主成分色譜峰保留時間的2倍，測量供試品溶液色譜圖上各雜質的峰面積並與對照溶液主成分的峰面積比較，計算雜質含量。 -
Results : when similarity was calculated between control and sample chromatography fingerprints, differences were found using different data treatments procedure, for example, correlating retention time and selecting internal standard peak
結果：保留時間校正前後相似度結果差異較大，內標峰選擇與否和選擇不同內標峰的各圖譜與對照圖譜的相似度均有差異。 -
Responsible for retention sample and regularly check retention sample as the approved sop
負責留樣程序，按程序定期檢查留樣。 -
