Polyphenolic compounds constitute one of the most characteristic classes of compounds in higher plants. Cinnamic acid derivates (e.g. caffeic, ferulic and p-coumaric acid) occur widely in higher plants as ester or glycosides. Quinic acid and monocaffeates, especially chlorogenic acid, are the most widely present ester derivates. Besides, a large number of other simple esters and glycosides (mai...

The objectives of the present field study were to examine the soil enzyme activities in the soil root zones of Plantago lanceolata and Plantago major in different heavy metal contaminated stands. Moreover, the investigations concerned the intensity of root endophytic colonization and metal bioaccumulation in roots and shoots. The investigated Plantago species exhibited an excluder strategy, acc...

In the present study we report the isolation of a phenylpropanoid glucoside, plantamajoside, together with rosmarinic acid, chlorogenic acid and luteolin-7-O-monoglucoside. This is the first report of these compounds from Plantago lagopus.

Zinc is a necessary micronutrient in plants whose deficiency can alter essential functions in plant metabolism. High concentrations of Zn can be potentially toxic to plants causing phytotoxicity by the formation of reactive oxygen species. On the other hand, sodium nitroprusside (SNP), a donor of nitric oxide (NO) can protect cells from oxidative damage produce by reactive oxygen species. In th...

The main objective of this study is to explore development of pharmaceutical excipients from the husk obtained from the seeds of Plantago ovata. Husk shows very good swelling property in water due to the major part of mucilage in it. Since swelling is one of the mechanisms of action of some tablet disintegrants, it is thought that the husk powder of Plantago ovata would be able to act as a tabl...
