There were
nine reference standards (including hesperidin, scopoletin, 5,6 dimethoxycoumarin,
5,7-dimethoxycoumarin, ferulic acid, diosmin, and vicenin), which
were purchased from Shanghai Yuan Ye Biotechnology Co., Ltd. (Shanghai,
China). Their purity was above 98% as tested using HPLC. Their identities
were confirmed by NMR spectroscopic methods and HR ESI-MS in a separate
publication. Methanol (MeOH) was bought from Chengdu Kelon chemical
reagent factory (Chengdu, China). The MS grade solvents including
acetonitrile (ACN) and formic acid (FA) were purchased from Sigma
(St. Louis, MO, USA).
The plant materials were collected from
seven different geographical regions in China and authenticated by
Prof. Yingjiao Zhang. Fresh materials were dried by the following
method. After air-drying, the sample was dried at −60 °C
at a vacuum of 0.1 kPa using an FD-1D-50 freeze-dryer (Beijing Bilang
Experimental Equipment Co., Ltd., Beijing, China). The dried slices
were milled into fine powder and stored at −18 °C for
the preparation of tests.

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.
