In traditional Chinese medicine, Gentiana macrophylla Pall have been prescribed for the treatment of pain and inflammatory conditions. In addition, it is a common Tibetan medicinal herb used for the treatment of tonsillitis, urticaria, and rheumatoid arthritis (RA), while the flowers of G. macrophylla Pall have been traditionally treated as an anti-inflammatory agent to clear heat in Mongolian medicine. The secoiridoid glycosides and their derivatives are the primary active components of G. macrophylla and have been demonstrated to be effective as anti-inflammatory agents.
METHODS AND RESULTS:
Solvent extraction and D101 macroporous resin columns were employed to concentratethe gentiopicroside. Gentiopicroside cytotoxicity was assessed by 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay; the toxicity of gentiopicroside in chondrocytes was reconfirmed using Hoechst staining. Western blotting, reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry were utilized to explore the protective effects and mechanisms of gentiopicroside prevents interleukin-1 beta induced inflammation response in rat articular chondrocyte.
The MTT assay demonstrated that 50, 500, and 1,500 μg/mL of gentiopicroside exhibited no significant toxicity to chondrocytes (P>0.05) after 24h. Using immunohistochemistry, ELISA, RT-PCR, Western blot method to explore the protective effect and mechanism of gentiopicroside on chondrocytes induced by IL-1β. The results showed some pathways of IL-1β signal transduction were inhibited by gentiopicroside in rat chondrocytes: p38, ERK and JNK. Meanwhile, gentiopicroside showed inhibition in the IL-1β-induced release of MMPs while increasing Collagen type II expression.
CONCLUSIONS:
The current study demonstrated that gentiopicroside exhibited a potent protective effect on IL-1β induced inflammation response in rat articular chondrocyte. Thus, gentiopicroside could be a potential therapeutic strategy for treatment of OA. | | Fitoterapia. 2003 Feb;74(1-2):151-4. | | Bioactivity of gentiopicroside from the aerial parts of Centaurium erythraea.[Pubmed: 12628413] | | Gentiopicroside (1), a secoiridoid glycoside isolated from the methanol extract of the aerial parts of Centaurium erythraea, has been assessed for antibacterial and free radical scavenging activities.

However, the molecular mechanism of gentiopicroside on the osteoclast formation remains unclear. The present study was designed to investigate the effects and mechanisms of gentiopicroside on receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclastogenesis. The results showed that pre-treatment with gentiopicroside significantly inhibited RANKL-induced osteoclast formation from mouse bone marrow macrophages (BMMs). In addition, we observed that gentiopicroside efficiently suppressed osteoclastogenesis-related marker genes expression in RANKL-stimulated BMMs. Mechanistically, gentiopicroside suppressed RANKL-induced the activation of JNK and NF-κB signaling pathways in BMMs. Taken together, the present study demonstrated that gentiopicroside inhibits RANKL-induced osteoclastogenesis through the inactivation of JNK and NF-κB signaling pathways. Thus, gentiopicroside may be a promising agent for the treatment of osteoporosis. |

METHODS AND RESULTS:
The experimental acute pancreatitis was made by retrograde injection of sodium taurocholate into the biliopancreatic duct in rats. Gentiopicroside was given orally and it markedly reduced the pancreatitis-evoked increase of serum amylase and lipase activity, decreased the pancreas mass/body mass index, tissue water content, TNF-α and IL-1β concentrations, and attenuated the histopathological changes and NF-κB p65 protein expression in pancreatic tissue.
CONCLUSIONS:
The results indicate that the function of gentiopicroside on acute pancreatitis may be related to inhibiting the release of inflammatory mediators and NF-κB p65 protein expression. | | Chinese Traditional & Herbal Drugs, 2003, 34(9):814-6 | | Studies on anti-inflammatory effect of gentiopicroside.[Reference: WebLink] | To study the anti-inflammatory effect of Gentiopicroside extracted from Radix Gentianae Marrophyllae.
METHODS AND RESULTS:
The models of auricular edema in mice induced by dimeth yl benzene, increased permeability of celiac blood capillary and body-twisting reaction induced by acetic acid, paw swelling induced by zymosan A, carrageenan a nd nystatin in rats or in mice were prepared. Then Gentiopicroside was given to the rats or mice by ig. Gentiopicroside inhibited th e auri cular edema, decreased the permeability of celiac blood capillary, reduced the p aw swelling induced by carrageenan and zymosan A, but not by nystation.
CONCLUSIONS:
Gentiopicroside extracted from Radix Gentianae Marrophyllae, exhibits obvious anti-inflammatory effects. | | Phytother Res . 2018 Feb;32(2):259-266. | | Protective effect of gentiopicroside from Gentiana macrophylla Pall. in ethanol-induced gastric mucosal injury in mice[Pubmed: 29226586] | | Gentiopicroside isolated from gentiana macrophylla Pall. belongs to iridoid glycosides. This study aimed to evaluate the protective effect of gentiopicroside against ethanol-induced gastric mucosal injury in mice. Mice were proactively administrated with gentiopicroside by intragastric administration once a day for 3 consecutive days. On the 3rd day, gastric ulcer in mice was induced with 70% ethanol after the last intragastric administration. The stomach tissues were submitted for evaluation of the severity of gastric mucosal alterations. Gentiopicroside administrated orally ameliorated the severity of gastric mucosal alterations. Oral administration of gentiopicroside significantly increased heat shock protein-70 and glutathione levels and superoxide dismutase activity, normalized epidermal growth factor and vascular endothelial growth factor levels, and decreased the levels of tumour necrosis factor-α, interleukin-6 and malondialdehyde, and myeloperoxidase activity in gastric tissue. These findings demonstrated that gentiopicroside has protective effect against ethanol-induced gastric mucosal injury in mice through the improvements of antioxidative and anti-inflammatory effects, as well as up-regulation of heat shock protein-70 level and normalization of epidermal growth factor and vascular endothelial growth factor levels. The results presented in this study provide some evidence for the development of a novel antigastric ulcer agent. |
