CAMAG Laboratory updated a HPTLC method to identify Horse tail (Equisetum arvense). It allows discrimination from the adulterant Equisetum palustre at the ≥5% level. The update of CAMAG application note F-12 is based on a collaborative study of Official Medicines Control Laboratories and features fast and simplified sample preparation.
The application note update F-12.1 can be downloaded from the Article webpage. Common Horse Tail or Equisetum arvense is listed in Ph.Eur.
The plant's stems are rich in silica and silicic acids, which help mend broken bones and form collagen. Horse tail is also used as a diuretic, a treatment for kidney and bladder complaints, and an external therapy for bleeding wounds.

Thin Layer ChromatographyThin-layer chromatography (TLC), also called planar chromatography, is an inexpensive and simple liquid chromatographic technique used to separate and identify small amounts of compound in a mixture, monitor progress of a reaction or determine purity of substance. TLC plates come in multiple sizes with common adsorbent layers being silica, aluminum oxide or cellulose and high-performance (HP-TLC) plates are also available for increased sensitivity. Other equipment needed includes TLC developing chambers, applicators, TLC sprayers and visualizing devices, such as a viewing cabinet and UV lamp.
