HPTLC methods updated
Four HPTLC methods have been updated with new images: Silybum marianum (Milk thistle fruit), Hypericum perforatum (St. John’s wort herb), Piper methysticum (Kava rhizome), and Zingiber officinale (Ginger rhizome).
Except for the method for Piper methysticum (mobile phase modified) there was no change to the method procedures.
