Artemisinin is an antimalarial substance obtained from dried leafs of Artemisia annua L. To monitor the plant during growth, determine time of harvest, or evaluate the commercial value of plant material the artemisinin content in the raw material has to be determined. | | A-87.1 | Determination of aucubin and catalpol in leaves of Ribwort Plantain (Plantago lanceolata) by HPTLC
Aucubin and catalpol are two iridoid glycosides, which are present in leaves of Plantago lanceolata L. (Ribwort Plantain) as well as in other medicinal plants. The content of the iridoid glycosides depends on the age of the plant. Young leaves may contain up to 9 % of iridoids whereas old leaves may only show traces. Catalpol is dominant in young leaves; in older ones the concentration of aucubin is higher. | F-12
