Phytochemical study of two plantago species: part I: sterols and flavonoids

The chemical investigation of Plantago major L. and P. lagopus L. was carried out. Oleanolic acid, beta sitosterol, campesterol and stigmasterol were isolated from the light petroleum extract. Luteolin and 6-hydroxy luteolin were isolated from the ether fraction of both plants. While the ethyl acetate fraction of P. major L. afforded three phenolic glycosides, viz; acteoside, luteolin-7-O-glucoside and 6-hydroxy luteolin-7-O-glucoside, that of P. lagopus L. afforded three 7-O-arabinosides of apigenin, luteolin and 6-hydroxy luteolin. The chemotaxonomic significance of the isolated arabinosides from P. lagopus L. was discussed

Phytochemical study of two plantago species: part II: iridoid glucosides

The isolation of aucubin, plantarenaloside, ixoroside, asperuloside and melampyroside from Plantago major L. and aucubin, plantrenaloside and asperuloside from Plantago lagopus L. [plantagenaceae] is reported. The identification of the isolated iridoid glucosides was carried out by spectroscopic analysis and comparison with authentic materials
