任何可检查水平都是不可接受的，因为21 CFR 211.176指明：依据特定的检测被污染产品中的程序检测，如果在非青霉素产品中发现任何水平的青霉素污染，则此产品不能销售。

The main content included: separation, depuration and appraisal of pathogens ; healing effect of the penicillin fluid to scaling the wound of the rotten sickness and the penicillin fluid prevented pathogens infection; the appraisal of pathogens secreting Pectolase and its influence; and the influence of Penicillin fluid to resistance of tree body .

主要内容包括：腐烂病病原菌的分离、提纯、鉴定；青霉素液对腐烂病刮治伤口的愈合效果以及阻止病原菌的侵染；病原菌分泌果胶酶的鉴定以及青霉素液对其的影响；青霉素液对树体抗病性的影响。

The synthetic route starts from penicillin G, peroxyacetic acid(8.5%) as Oxidizing Agent to get penicillin G sulfoxide; esterifided with p-nitrobenzyl bromine to synthesize penicillin G sulfoxide ester; we synthesize 3-exomethylenecepham sulfoxide ester with phthalimide potassium and 4A molecular sieve as acid scavenger to open the ring, SnCl_4 as catalyzation to close the ring. The yield is over 60%.

本研究采用的合成路线为：以青霉素G钾盐为原料，选用工业过氧化氢制备的过氧乙酸(22.3%)稀释至8.5%为氧化剂，氧化得青霉素亚砜；采用对硝基溴苄为酯化试剂，制备青霉素亚砜酯；以NCP(N-氯代邻苯二甲酰亚胺)为开环试剂，酞酰亚胺钾和4A型分子筛为酸清除剂，顺利开环；再经无水SnCl_4催化闭环得3-环外亚甲基头孢亚砜酯，最终产率在60%以上。
