摘要

The identification and determination of major flavonoids in endemic species Plantago schwarzenbergiana and Plantago reniformis is reported for the first time. Flavonoids and phenylpropanoid glycoside acteoside were also determined in four other Plantago species, namely Plantago atrata, Plantago coronopus, Plantago holosteum and Plantago lanceolata, using LC-MS/MS and HPTLC analysis, respectively. Apigenin was found to be the major flavonoid in P. schwarzenbergiana, while luteolin and luteolin-7-O-glucoside were dominant compounds in P. atrata, P. coronopus, P. holosteum and P. lanceolata. Luteolin and apigenin were present in P. reniformis in lowest amounts, and corresponding glucosides were detected in traces only. The acteoside concentration was the highest in P. lanceolata (21.71聽mg/g dry weight). The extracts were also evaluated regarding the contents of total phenolics, phenylpropanoid glycosides (PPGs), and iridoids. P. lanceolata contained the highest concentrations of total phenolics and PPGs, while P. holosteum was the richest in iridoids. Moreover, xanthone-C-glucoside mangiferin was not reported in Plantago species before.
