The plant material was found rich in kaempferol-3-O-rutinoside, quinic acid, arginine, palmitic acid, and β-sitosterol [60]. Karioti and coworkers [61] developed an HPLC-DAD-MS method to analyze the “Olivis” preparation, a blend of four herbal drugs, namely Crataegus oxyacantha L., Olea europea L., Capsella bursa-pastoris L. and Fumaria officinalis L. The lack of the marker constituents of some of the declared plant species (i.e. C. bursa-pastoris) and the presence of banned adulterants, responsible for the strong antihypertensive effect of the supplement prompted to analyze this herb. The analyses proved the presence of indole alkaloids belonging to the group of Rauwolfia sp., such as ajmaline, reserpine and yohimbine. Seven flavonoids and two caffeoyl acid derivatives were found in C. bursa-pastoris [61].
