The petal extracts were analyzed using an LC–ESI–MS/MS system (high-performance liquid chromatography (HPLC) Shim-pack UFLC SHIMADZU CBM30A system; MS, Applied Biosystems 6500 Triple Quadrupole). The analysis was performed using YMC C30 columns (3 µm, 2 mm × 100 mm) and an acetonitrile:methanol (3:1, v/v) (0.01% BHT):methyl tert-butyl ether (0.01% BHT) solvent. The solvent gradient was as follows: 85:5 (v/v) at 0 min, 75:25 V/V at 2 min, 40:60 (v/v) at 2 min 30 s, 5:95 (v/v) at 3 min, 5:95 (v/v) at 4 min, 85:15 (v/v) at 4 min, and 85:15 (v/v) at 6 min. The flow rate was 0.8 mL/min. The temperature was maintained at 28 °C, and the injection volume was 5 μL.
The effluent was alternatively connected to an ESI-triple quadrupole-linear ion trap (Q TRAP)-MS (API 6500 Q TRAP LC/MS/MS System) equipped with an APCI Turbo Ion-Spray interface operating in a negative ion mode. The equipment was controlled using Analyst 1.6.3 software (AB Sciex). The APCI source operation parameters were as follows: ion source, turbo spray; source temperature 350 °C; curtain gas (CUR) was set at 25.0 psi; and collision gas (CAD) was medium. The DP and CE settings were further optimized for individual MRM transitions. A specific set of MRM transitions were monitored for each period, according to the plant hormones eluted.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
