Two isomeric phenylethanoid glycosides, acteoside and isoacteoside were isolated and purified from the seeds of Plantago psyllium L. for the first time by high-speed counter-current chromatography (HSCCC) using a solvent system consisting of ethyl acetate-water (1:1, v:v). By injecting 200 mg of the
OBJECTIVE
To study the chemical constituents of Plantago asiatica seeds.
METHODS
The constituents were isolated from the seeds of Plantago asiatica by column chromatography over silica gel, MCI gel, macroporous resin HP-20, Sephadex LH-20, Polyamide and by preparative HPLC. Their structures were
OBJECTIVE
To elucidate the immunomodulatory mechanism of phenylethanoid glycosides from the seeds of Plantago asiatica by testing its effects on the maturing of murine bone marrow derived dendritic cells (DCs).
METHODS
Monocytes generated from bone marrow of Balb/cj mouse were cultured for 6 days in
An ethanolic spissum extract of the aerial parts of Plantago lanceolata L. was examined for antispasmodic activity on isolated ileum and trachea of the guinea-pig. Isolated constituents were investigated as well. The P. lanceolata extract inhibited the contractions of the guinea-pig ileum that were
Plants of the Plantago genus are widely used in Turkish folk medicine especially for the treatment of wound, abscess, and inflammation. The aqueous extract and five phenylethanoid glycosides acteoside (1), arenarioside (2), echinacoside (3), isoacteoside (4), and leucosceptoside A (5) isolated from
The five phenylethanoids, acteoside (1), cistanoside F (2), lavandulifolioside (3), plantamajoside (4) and isoacteoside (5) were isolated from the herb of Plantago lanceolata L. (Plantaginaceae). Compounds 1, the major phenylethanoid in the herb of P. lanceolata L., and 4, the major phenylethanoid
The XOD inhibitory effects of Plantaginis Semen, that is, the seeds of P. asiatisca, and its representative four single compounds, acteoside, 1H-indolo-3-carbaldehyde, isoacteoside, and myristic acid, were evaluated by electron transfer signal blocking activities (ETSBA), which is based on the
Plantago asiatica L. seeds is a common folk medicine with a long history of medical use in China because of its antipyretic, diuretic, and expectorant properties. It has been applied to treat hypertension clinically due to its diuresis, however, its efficacy and mechanisms on
Ethanolic extract of the seeds of Plantago asiatica L. showed significant inhibitory activity of angiotensin-converting enzyme (ACE) determined by monitoring the transformation from a substrate hippuryl-histidyl-leucine (HHL) to the product hippuric acid (HA) in vitro using an UPLC-MS method. The
The seed of Plantago asiatica L. is one of the most popular folk herbal medicines used in China and other Asian countries. In this study, phenylethanoid glycosides and polysaccharides were isolated from the seed of P.asiatica L. by using phytochemical investigation methods. A screening model of
