Efficacy of verbascoside, echinacoside, crenatoside on altitude-induced fatigue in rats and possible mechanism.
To study the efficacy and mechanism of three phenylethanoid glycosides (PhGs) (verbascoside, echinacoside, and crenatoside) on altitude-induced fatigue in rats.. Altitude-induced fatigue model rats were established in a large hypobaric chamber. Swimming time, energy storage substances, metabolic enzymes, and metabolites were used to evaluate the anti-fatigue activities and mechanism of three PhGs (verbascoside, echinacoside, and crenatoside) (150 mg/kg, intragastric administration) in the hypoxic environment.. The three PhGs, especially verbascoside, could prolong the swimming time of rats, ameliorate the edema and inflammatory infiltration of liver and skeletal muscle, increase the level of energy storage substances, reduce the decomposition of proteins, and exhibit positive effects on the metabolism-related enzyme activity and metabolites.. The PhGs, especially verbascoside, are very potential with anti-fatigue activity in hypoxia. The mechanism may be explained with regulation of energy metabolism and reduction of oxidative stress.

[Comparison of distribution of verbascoside in normoxic and hypoxic rats].
This study established a high performance liquid chromatography(HPLC) method for the simultaneous determination of verbascoside(VB) and its main metabolite caffeic acid(CA) in rat tissue samples. A low-pressure low-oxygen animal experimental chamber was used to simulate the plateau environment for establishing the hypoxic rat model. After intragastric administration of 300 mg·kg~(-1) VB, the normoxic and hypoxic rats were sacrificed for the collection of heart, liver, spleen, lung, kidney, brain, muscle, large intestine, small intestine, and stomach tissue samples at the time points of 30, 60, and 90 min. VB and CA concentrations in each tissue sample were measured by HPLC, and the distribution of VB and CA in normoxic and hypoxic rats was compared. The results showed that after intragastric administration, VB can be rapidly absorbed and distributed into various tissues including brain in both normoxic and hypoxic rats, indicating that VB can pass through the blood-brain barrier. In the gastrointestinal tract, VB was mainly distributed in small intestine, which suggested that the main absorption site of VB was small intestine. A large amount of VB was detected in muscle and lung, and only a small amount in other tissues. CA was detected in other tissues except brain, heart, and muscle. Small intestine had the most abundant CA, followed by stomach, large intestine, and kidney, and only a small amount of CA was detected in the liver, spleen, and lung(<50 ng·mL~(-1)). The results indicated that VB may be mainly absorbed and metabolized in the gastrointestinal tract to produce CA and was possibly excreted through kidney. Compared with normoxic rats, hypoxic rats had reduced and slow distribution of VB and increased ratio of VB concentration in tissue to plasma, which implied that the relative proportion of VB from systemic circulation to tissues was increased in hypoxic rats. This study provides a basis for the application of VB in anti-hypoxia therapy and for the formulation of anti-hypoxia dosing regimens.

Effect and mechanism of verbascoside on hypoxic memory injury in plateau.
Verbascoside is a water-soluble natural phenylethanoid glycoside and distributes widely in plants. It has been proved with antioxidant, neuroprotective, anti-inflammatory, antibacterial, and immunomodulatory bioactivities. In this experiment, the effect and mechanism of verbascoside on hypoxic memory injury were studied in a low-pressure and low-oxygen chamber. Verbascoside (50, 150, and 300 mg/kg) was intragastrically administered once a day for 7 days. On the fourth day, rats were placed in the chamber to simulate a 7,500 m high-altitude environment The eight-arm maze was used to test the memory ability. The levels of MDA, GSH, and T-SOD in plasma, brain-NH, and hippocampus were detected. The mRNA expression of mTOR, P70S6K, and 4E-BP1 in the hippocampus tissue was determined by PCR. The protein expression of P-mTOR, P-P70S6K, P-4E-BP1, and Cleaved Caspase-3 in the hippocampus tissue was determined by western blot. The results indicated that administration with verbascoside could obviously reduce the working memory error, reference memory error, total errors, and total time; relieve the neuron damage in CA Topics: Altitude; Animals; Glucosides; Hippocampus; Hypoxia; Male; Memory Disorders; Phenols; Rats; Rats, Wistar; TOR Serine-Threonine Kinases | 2019 |
