Excessive activation of macrophages is implicated in various inflammation resulted injuries. Saponins from Panax japonicus (SPJ) have been shown to possess anti-inflammatory activities. However, whether Chikusetsusaponin V (CsV), the most abundant component of SPJ, can exert anti-inflammatory
BACKGROUND
The rhizomes of Panax japonicus are used as a folk medicine for treatment of life-style related diseases such as arteriosclerosis, hyperlipidemia, hypertension and non-insulin-dependent diabetes mellitus as a substitute for ginseng roots in China and Japan. Obesity is closely associated
Fas-mediated apoptotic cell death of a human keratinocyte cell line, HaCaT cells, and of a murine keratinocyte cell line, Pam212 cells, was suppressed by pre-treatment with a methanol extract from the roots of Panax japonicus C.A. Meyer. Activity-guided fractionation led to the isolation of
Chikusetsusaponin V (CsV), a saponin from Panax japonicus, has been reported to inhibit inflammatory responses in lipopolysaccharide (LPS)-induced macrophage cells. However, whether CsV could alleviate LPS-induced liver injury in vivo and the potential mechanisms involved remain unclear. In the
Two new dammarane-type triterpenoid saponins, chikusetsusaponin LM1 (1), chikusetsusaponin LM2 (2), and three known triterpenoid saponins, ginsenoside Re (3), ginsenoside Rg1 (4), ginsenoside F3 (5), were isolated from the leaves of P. japonicus C. A. Meyer collected in Miyazaki prefecture, Japan.
In the course of a chemical study on pure ginsenosides, a ginsenoside-Rg2 was isolated as colorless needles, from the lateral root of Panax ginseng C. A. Meyer. For the characterization of Rg2, a chikusetsusaponin-I (ginsenoide-Rg2) was isolated as colorless needles from rhizome of Panax japonicus
The antihepatotoxic effects of ginsenosides, saponins from PANAX GINSENG, and their aglycones were investigated utilizing carbon tetrachloride (CCl (4))- and galactosamine (GalN)-induced cytotoxicity in primary cultured rat hepatocytes. Prominent protective actions were found with 20(
A HPLC method for the simultaneous determination of 11 triterpene saponins with four-type aglycones (protopanaxadiol, protopanaxatriol, ocotillol and oleanolic acid types) in Ginseng drugs was developed and validated. Using a gradient of acetonitrile and 10 mM K-phosphate buffer (pH 5.80) as the
Ultrafiltration liquid chromatography-mass spectrometry (UFLC-MS) is an efficient method that can be applied to rapidly screen and identify ligands for acetylcholinesterase (AChE) from the leaves of Panax japonicus. Using this method, we identified 5 major compounds, chikusetsusaponins V, Ib, IV,
From rhizomes and roots of Panax vietnamensis Ha et Grushv., Araliaceae, commonly known as Vietnamese Ginseng, two new acetylate saponins named vina-ginsenoside-R1 (13) and vina-ginsenoside-R2 (15) were isolated. On the basis of chemical and spectral data, 13 was formulated as monoacetyl
Using HCl/ethanol-induced ulcer in rats as a screening model, an anti-ulcer effect was observed for a methanol extract of Panax japonicus rhizome, saponin fractions and chikusetsusaponin III. Results suggest that the gastric mucous membrane-protective effect of the methanol extract is likely to be
Panajaponin, a new glycosphingolipid compound (1), together with eight known compounds, 28-glu-oleanolic acid ester (2), chikusetsusaponin IVa (3), chikusetsusaponin IV (4), ginsenoside Ro (5), ginsenoside Re (6), notoginsenoside R2 (7), ginsenoside Rg2 (8) and adenosine (9), was isolated from Panax
The effects of a 70% methanol extract (PMe) obtained from the rhizomes of Panax japonicus C. A. Meyer on experimental thrombosis and fibrinolysis were investigated in vivo and in vitro. PMe showed a promotive effect on the activation of the fibrinolytic system as determined by the euglobulin lysis
OBJECTIVE
To establish a quality standard for Panax japonicus rhizome.
METHODS
Ginsenoside Ro and Chikusetsusaponin IVa were used as reference substances in the TLC identification and HPLC method. Additionally, acid insoluble ash and moisture were determined according to the procedures recorded in
