Activation of macrophages by the ophiopogon polysaccharide liposome from the root tuber of Ophiopogon japonicus

International Journal of Biological Macromolecules, 2016
This study evaluated the immunomodulatory effects of ophiopogon polysaccharide liposome (OPL) on macrophages in vitro. The phagocytic activity, the secretion of nitric oxide (NO) and inducible nitric oxide synthase (iNOS), the level of cytokines, chemokines and the expression of CD14 and MHC-II costimulatory molecules were measured. Results showed that

Antioxidative and immunological activities of ophiopogon polysaccharide liposome from the root of Ophiopogon japonicus

Carbohydrate Polymers, 2016
The antioxidative and immunoregulatory activities of ophiopogon polysaccharide liposome (OPL) were investigated. The results demonstrated that the radical-scavenging activity increased along with the increasing of OPL concentrations, and the scavenging capability of OPL was slightly stronger than ophiopogon polysaccharide (OP) in vitro. In vivo, OPL at

Homoisoflavonoids from Ophiopogon japonicus Ker-Gawler

Phytochemistry, 2003
From the ethyl acetate extract of the tuberous roots of Ophiopogon japonicus (Liliaceae) eight known and five new homoisoflavonoidal compounds were isolated. The new compounds are 5,7-dihydroxy-8-methoxy-6-methyl-3-(2'-hydroxy-4'-methoxybenzyl)chroman-4-one (1), 7-hydroxy-5,8-dimethoxy-6-methyl-3-(2'-hydroxy-4'-methoxybenzyl)chroman-4-one (2), 5,7 ...

Studies on chemical constituents of Ophiopogon japonicus

Journal of Asian Natural Products Research, 2014
Two new and six known steroidal glucosides were isolated from the tuber of Ophiopogon japonicus. The new steroidal glucosides were established as (20R,25R)-26-O-β-d-glucopyranosyl-3β,26-dihydroxycholest-5-en-16,22-dioxo-3-O-α-l-rhamnopyranosyl-(1 → 2)-β-d-glucopyranoside (1) and 26-O-β-d-glucopyranosyl-(25R)-furost-5-en-3β,14α,17α,22α,26-pentaol-3-O-α ...

Cytotoxic steroidal saponins from Ophiopogon japonicus

Steroids, 2013
Four new steroidal saponins, named ophiopogonin P-S (1-4), together with eleven known ones (5-15) were isolated from the tuberous roots of Ophiopogon japonicus. Their structures were elucidated by spectroscopic and chemical analysis. Compounds 2-15 were evaluated for their cytotoxic activity against five human tumor cell lines (HepG2, HLE, BEL7402 ...

Steroidal saponins from the tuber of Ophiopogon japonicus

Steroids, 2012
Eight novel steroidal saponins, ophiopogonins H-O (1-8), along with seven known steroidal saponins (9-15) were isolated from the tubers of Ophiopogon japonicus. The structures of these new compounds were determined by detailed spectroscopic analysis, including extensive 1D and 2D NMR data, and the analysis of hydrolytic reaction products. For the first

Steroidal glycosides from tubers of Ophiopogon japonicus

Journal of Asian Natural Products Research, 2006
A new steroidal saponin, named ophiopogonin E (1), has been isolated from the tubers of Ophiopogon japonicus, along with five known steroidal saponins (2-6). The structure of the new steroidal glycoside was characterized by spectroscopic analysis and acid-catalyzed hydrolysis as pennogenin 3-O-beta-D-xylopyranosyl (1 --> 4)-beta-D-glucopyranoside (1).
