Two new guaianolides, named chinensiolides D (5) and E (6), were isolated from Ixeris chinensis Nakai, their structures determined to be 10α-hydroxy-3-oxoguaia-11(13)-eno-12,6α-lactone 10α-hydroxy-3β-O-[2,6-di(p-hydroxyphenylacetyl)-β-glucopylanosyl]guaia-4(15),11(13)-dieno-12,6α-lactone (6). The first isolation of (11S)-10α-hydroxy-3-oxoguaia-4-eno-12,6α-lactone (4) natural sources its characterization are also reported. Chinenciolide (6) showed significant growth inhibitory activity toward...
Natural hydrogels are growing in interest as a priority for wound healing. Plant polysaccharides have variety of biological pharmacological activities, and chitosan proven strong antimicrobial effects, but prepared with alone certain deficiencies. Polysaccharides from flowers Lonicera japonica Thunb. (LP) the aerial parts Mentha canadensis L. (MP) were extracted oxidized by sodium periodate (NaIO4) then cross-linked oxidized-carboxymethylated (O-CCS) to develop plant-...
Three new guaianolides, 10α-hydroxy-3-oxoguaia-4(15),11(13)-dieno-12,6α-lactone (1), 10α-hydroxy-3-oxo-4βH-guaia-11(13)-eno-12,6α-lactone (2), and 10α-hydroxy-3-oxoguaia-4,11(13)-dieno-12,6α-lactone (3), named chinensiolides A, B, C were isolated from the whole plant of Siyekucai (Ixeris chinensis). The structures determined by HREIMS, UV, IR, one- two-dimensional NMR techniques (1H 13C NMR, COSY, HMQC, HMBC, NOE difference NOESY experiments). Compounds 1 2 indicated to be a mixture flexible...
A new wortmannine derivative named E (1) was isolated from Talaromyces wortmannii LGT-4, an endophytic fungus of Tripterygium wilfordii. Its structure established by 1D and 2D NMR spectra.
In this study, the extraction conditions ofNostoc communeVauch polysaccharide (NCVP) were optimized by single factor and orthogonal experiments. Then, NCVP microcapsules (NCVPM) prepared. After analyzing microcapsule structural thermal characteristics, skin wound healing ability was studied establishing back trauma rat models. Results showed that yield 10.37% under following optimum conditions: 210 min time, solid-liquid ratio of 1:50 temperature 90 °C. The overall performance best when...
Abstract The crude polysaccharide (CPNP) of Codonopsis pilosula was obtained by hot-water extraction technology. kinetic model established according to Fick’s first law diffusion and related parameters studied. CPNP microcapsules were prepared blending with sodium alginate, Ca 2+ ions CPNP. quality control (drug loading rate, embedding rate release etc) analyzed pharmacopeas standards. structure feature also determined various methods. wound healing ability different concentration evaluated...
A pot experiment investigated interactions between foliar endophytic (EP, Neotyphodium lolii) and root arbuscular mycorrhizal (AM, Glomus mosseae) fungi in Lolium perenne. The effects of three phosphorus (P) forms (KH2PO4-P, phosphate rock-P (PR) phytate-P) on EP AM colonisation plant growth parameters were also assessed. vesicular structures estimated by microscopic counting fungal concentrations quantified qPCR G. mosseae N. lolii specific genes. Significantly more formed roots EP-free...
18 strains endophytic fungi were isolated from leaves and branches of Cynanchum chinense. The antioxidant antibacterial activities the broth studied by vitro methods. results showed that all tested have different degree DPPH radical scavenging activities. At concentration 0.1mg/mL, 8 played a certain activities, with rate more than 50%, these, extract 1 strain notable activity, 84.5%. 15 hydroxy abilities, but activity was weak, max rates 14.5% at 0.8 mg/mL. 9 active against six test...
