selaginella seemannii/抗菌的

In Mexico about 4,000 plant species have some medicinal use. The aim of this work was to evaluate the antimicrobial activity of six Mexican medicinal plants against fungi and Gram-positive and Gram-negative bacteria. Methanolic extracts were prepared from the Mexican medicinal plants Amphypteringium

We investigated novel antibacterial and synergistic activities of isocryptomerin isolated from Selaginella tamariscina. Isocryptomerin showed potent antibacterial activity against Gram-positive and Gram-negative bacterial strains including clinical isolates of antibiotic-resistant species such as

Selaginella tamariscina is a traditional herb used in medicine. Phytochemical amentoflavone, a biflavonoid class of flavonoids, was isolated from the plant of Selaginella tamariscina. In this study, the antibacterial effects and combination effects of amentoflavone and conventional antibiotics such

Six selaginellin derivatives, including three new analogues selaginellins D-F (1-3), were isolated from the EtOAc extract of the whole plant of Selaginella pulvinata (Hook. et Grev.) Maxim. Their structures were determined on the basis of extensive physical and chemical evidence. Compounds 1 and 4

Amentoflavone is a biflavonoid compound with antioxidant, anticancer, antibacterial, antiviral, anti-inflammatory, and UV-blocking activities that can be isolated from Torreya nucifera, Biophytum sensitivum, and Selaginella tamariscina. In this study, the molecular mechanism underlying

The recent study deals with the synthesis and characterization of silver nanoparticles bounded to Selaginella bryopteris (Sanjeevini) Plant extract (SPE) as reducing and capping agents. Selaginella bryopteris plant extract silver nanoparticles (SPE@Ag-NPs) was characterized by PXRD, UV-Vis., FESEM,

Five new carboxymethyl flavonoids named 5-carboxymethyl-3', 4', 7-trihydroxyflavone (1), (2S)- 5-carboxymethyl-3', 4', 7-trihydroxyflavonone (2a), (2R)-5-carboxymethyl-3', 4', 7-trihydroxyflavonone (2b), (2S)-5-carboxymethyl-4', 7-dihydroxyflavonone (3), 5- carbomethoxymethyl-4', 7-dihydroxyflavone

Eight new pyrrolidinoindoline alkaloids (1-8) were isolated from the whole plant of Selaginella moellendorfii. Their structures were determined by mass spectrometry, 1D and 2D NMR spectroscopy, and chemical interconversions. These alkaloids have a 3-carboxybut-2-enyl group at C-3a and two methyl
