A new water-soluble pyrrolizidine alkaloid quaternary salt, N-methyl-O7, O9-diangeloyl-1-hydroxyl platynecinium chloride, a new saturated pyrrolizidine alkaloid, O7-angeloylturneforcidine, a new saturated otonecine pyrrolizidine, 1,2-dihydrosenkirkine, a known alkaloid, O7-angeloylheliotridine and its N-oxide were isolated from Senecio integrifolius var. fauriri. The structures of the alkaloids and their stereochemistry have been elucidated by NMR analysis. © 1991.
