BACKGROUND
Panax ginseng and its major component, ginsenosides, are widely used for the prevention of various disorders in oriental medicine.
OBJECTIVE
To evaluate the effect of ginsenoside Rc (Rc), one of the active constituents in Panax ginseng, on glucose uptake in C2C12
Korean Red Ginseng (KRG) is an herbal medicine prescribed worldwide that is prepared from Panax ginseng C.A. Meyer (Araliaceae). Out of ginseng's various components, ginsenosides are regarded as the major ingredients, exhibiting anticancer and anti-inflammatory activities. Although recent studies
The purpose of this study was to investigate the herb-drug interactions involving red ginseng extract (RGE) or ginsenoside Rc with valsartan, a substrate for organic anion transporting polypeptide (OATP/Oatp) transporters. In HEK293 cells overexpressing drug transporters, the protopanaxadiol
BACKGROUND
Ginsenoside Rc (G-Rc) is one of the major protopanaxadiol-type saponins isolated from Panax ginseng, a well-known medicinal herb with many beneficial properties including anticancer, anti-inflammatory, antiobesity, and antidiabetic effects. In this study, we investigated the effects of
The purpose of the study was to investigate the effects of two constituents of Panax notoginseng flower extract, Ginsenoside Rb2 and Rc, on human sperm motility and progression in vitro. Semen samples were collected from 20 patients with sperm motility between 20% and 40% of normal. All samples had
Further investigation on the saponin composition of rhizomes and roots of Panax vietnamensis HA et GRUSHV. has resulted in the isolation and structural elucidation of seven new dammarane saponins named vina-ginsenosides-R3 (12), -R4 (11), -R5 (16), -R6 (17), -R7 (6), -R8 (20), -R9 (22), together
In this study, simple ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass tandem mass spectrometry is used to characterize the absorbed components in rat plasma after the oral administration of saponins from the leaves of Panax notoginseng. Seventeen prototype
Panax notoginseng is famous for its important therapeutic effects and commonly used worldwide. The active ingredients saponins have distinct contents in different tissues of P. notoginseng, and they may be related to the expression of key genes in the synthesis pathway. In our study,
Six saponins were isolated from the fruit pedicels of Panax notoginseng for the first time. They were identified as ginsenoside-Rc, -Rb3, -Re, notoginsenoside-Fe, -R1 and gypenoside IX by chemical and spectroscopic analysis.
Four new dammarane-type triterpenoid saponins such as chikusetsusaponin LM3 (1), chikusetsusaponin LM4 (2), chikusetsusaponin LM5 (3), chikusetsusaponin LM6 (4), and twenty known triterpenoid saponins such as ginsenoside Rb3 (5), ginsenoside Rc (6), ginsenoside Rd (7), ginsenoside Re (8),
Seven new dammarane-type triterpenoid saponins, chikusetsusaponin FK1 (1), chikusetsusaponin FK2 (2), chikusetsusaponin FK3 (3), chikusetsusaponin FK4 (4), chikusetsusaponin FK5 (5), chikusetsusaponin FK6 (6), and chikusetsusaponin FK7 (7), and eleven known triterpenoid saponins, ginsenoside Rb3
UNASSIGNED
Panax notoginseng leaves (PNL) exhibit extensive activities, but few analytical methods have been established to exclusively determine the dammarane triterpene saponins in PNL.
UNASSIGNED
Ultra-performance liquid chromatography coupled with time-of-flight mass spectrometry (UPLC/Q-TOF MS)
Methanol and water are commonly used solvents for chemical analysis and traditional decoction, respectively. In the present study, a high-performance liquid chromatography with ultraviolet detection method was developed to quantify 11 saponins in Panax notoginseng flower extracted by aqueous
A new dammarane-type triterpenoid saponin, chikusetsusaponin VII (1), and nineteen known triterpenoid saponins, ginsenoside Rb1 (2), ginsenoside Rb3 (3), ginsenoside Rc (4), ginsenoside Rd (5), ginsenoside Re (6), ginsenoside Rg1 (7), ginsenoside Rg2 (8), ginsenoside Rh1 (9), notoginsenoside R1
