Looking for new plant sources of immunomodulating agents polysaccharide-rich fractions (PS) from Menyanthes trifoliata L. (Menyanthaceae) have been isolated. The herb of Menyanthes trifoliata L. was sequentially extracted with water, 0.1 M NaOH, 8% CH3COOH, and 1 M NaOH. After dialysis and
A new lupane triterpenoid, 23-O-trans-feruloylcylicodiscic acid (1), as well as four known analogues (2‒5), was isolated from the EtOAc fraction of Menyanthes trefoliata. The structure of compound 1 was elucidated on the basis of extensive spectroscopic analysis, including 2D NMR data. The
Comparison of the methanolic extracts from leaves, stems, and rhizomes of MENYANTHES TRIFOLIATA L. by TLC showed that the main compounds are dihydrofoliamenthin, menthiafolin, and loganin, whereas foliamenthin was lacking. The monoterpene carboxylic acid of dihydrofoliamenthin was determined to be a
OBJECTIVE
We developed microsatellite primers to investigate genetic diversity and population genetic structure of the endangered herb Menyanthes trifoliata.
RESULTS
Using the microsatellite-enriched library method, we identified 10 primer pairs in M. trifoliata. The primers amplified nine di- and
The influence of oral administration of a water decoction made from the rhizomes of Menyanthes trifoliata L. (MtL) was studied in rats, before and after exposure of 45 min of renal ischemia. Under normal conditions (preischemia) MtL treated kidneys behave similarly to untreated kidneys, measured as
Menyanthes trifoliata L. is used in Swedish traditional medicine for the treatment of inflammatory diseases of the kidney, e.g. glomerulonephritis. Earlier studies have shown that MtL increases glomerular filtration rate after renal reperfusion ischemia. This activity was suggested to be
Menyanthes trifoliata L. has been used in traditional medicine for centuries. It exists in Asia, Europe, North America and in Morocco and is exploited as a remedy for anemia and lack of appetite. This plant shows many pharmacological properties, but its most interesting one is its anti-cancer
The long-term effects of UVB exclusion and temperature on the methanol extractable (ME) phenolics (flavonoids, phenolic acids) and iridoids of Menyanthes trifoliata L. (Mt) leaves were studied in northern Finland (68 degrees N) using wooden frames covered with filters for UVB exclusion (polyester
Menyanthes trifoliata L. is a valuable medical plant found in Europe, North America, and Asia, which grows on peat bogs and swamps. It has long been used in folk medicine as a remedy for various ailments. This is the first report to demonstrate the protective antioxidant and anti-inflammatory
Chosen to reflect biodiversity in a phylogenetic sense, 100 fractionated plant extracts were screened in vitro for cytotoxicity following extraction and fractionation (polypeptide isolation). Of these 100 extracts, 30 were selected and then characterized preliminarily for antitumor potency and mode
