The occurrence of potentially toxic pyrrolizidine alkaloids (PAs) in herbal medicines (HMs) is currently intensely being discussed Europe. Pyrrolizidine alkaloids, particularly the 1,2-unsaturated PAs, are undesired compounds HMs due to their potential hepatotoxic and carcinogenic properties. In this study, 98 widely patronized from six popular German retail supermarkets/drugstores, as well pharmacies, were analyzed by high-performance liquid chromatography-electrospray ionization-tandem...

There is a vast amount of information about the nutritional and medicinal properties honey as result its numerous benefits. However, honeys have been found to be contaminated with hepatotoxic carcinogenic pyrrolizidine alkaloids (PAs) on account bees foraging PA-containing plants. This study deals analysis PAs in tropical emanating from different agro-ecological zones Ghana order assess potential health risk. 48 samples were analysed using high-performance liquid chromatography-electrospray...

Abstract Introduction Growing demand for heart‐healthy omega‐3 long‐chain polyunsaturated fatty acids (n‐3 LC‐PUFA), eicosapentaenoic acid (EPA) and docosahexaenoic (DHA), is putting stress on wild fish stocks. There now a compelling need new novel sources of non‐traditional seed oils containing high stearidonic (SDA), precursor EPA DHA, to reduce this demand. The oil Lappula squarrosa one the richest SDA, however, plant has been found contain toxic pyrrolizidine alkaloids (PAs). Objective...
