Optimisation of isolation procedure for pyrrolizidine alkaloids from Rindera umbellata Bunge.[Pubmed:
25528897]
METHODS AND RESULTS:
The yields of six PAs (7-angeloyl heliotridane, 7-angeloyl heliotridine, lindelofine, 7-angeloyl rinderine, Punctanecine and heliosupine) were monitored by GC-MS/FID. The best results for the isolation all of six PAs were obtained when the extraction was performed with 1 M sulphuric acid (30 mL per 1.00 g of dried sample) by overhead rotary mixer during three days.
