These uncontaminated explants showed that morphogenetic potential were 70%-75% and each responding explant had 1.2-1.4 shoots formation on MS medium supplemented with 2 mg/L NAA and 16 mg/L BA. Moreover, adding antibiotics (100 mg/L Rifampicin and 100 mg/L Gentamycin) to solidify MS contained 3% galactose were tested, results showed the lowest contamination rates were 20% and 1.0-1.2 shoots were regenerated per responding explant. The antibiotic treatments with 100 mg/L Rifampicin and 100 mg/L Gentamycin could reduce internal contaminants, while the addition of antibiotics into medium in vitro culture led to phototoxic phenomena of axillary explants, morphogenetic potential lost and the growth of regenerant was also inhibited.

The results showed that the MS2 fragmentation pathways of DASSSB were affected by the character and position of substitutes on salicylidene phenyl. The C=N cleaving to form fragmentation ion [M+H-283](superscript +) was dominant for DASSSB compounds with electron-donating group on the C4 of the salicylidene phenyl; while fragmentation ion [M+H-254] (superscript +) forming by C-C cleavage of the β-position of C=N was dominant for DASSSB compounds with electron-withdrawing group on the C5 of the salicylidene phenyl.

结果显示，这些化合物的ESI-MS/MS裂解方式与它们分子中水杨醛苯环上取代基的性质和位置有关：当水杨醛苯环上4位连接供电子取代基时，分子以CN双键断裂为主，生成[M+H-283]碎片离子；当水杨醛苯环上5位连接吸电子取代基时，分子以CN双键β位的C-C键发生断裂为主，生成[M+H-254]碎片离子。
