Character and laxative activity of polysaccharides isolated from Dendrobium officinale

Journal of Functional Foods, 2017
Dendrobium officinale was separated into total polysaccharides (DOP) and supernatant (DOS) to investigate the laxative ingredients and mechanism in normal and constipated mice induced by diphenoxylate or water fasting. The molecular weight and components of DOP were determined by HPGPC, HPLC and LC-MS.

Encephalopathy: Cause, Pathogenesis, and Treatment

MedComm, Volume 7, Issue 6, June 2026.
Various encephalopathies (sepsis‐associated, hepatic, hypoxic–ischemic, diabetic, uremic, toxic) have incompletely elucidated pathogenesis, which severely restricts targeted therapy development. Small molecule drugs show unique multitarget potential but face toxicity, poor blood–brain barrier penetration and unclear specificity.

A Triterpenoid‐Enriched GLE70 Fraction From Ganoderma lingzhi Ameliorates Alcoholic Liver Disease via Multi‐Target Regulation

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
GLE fractions were prepared from Ganoderma lingzhi using gradient ethanol elution and evaluated for their biological activities. Among the fractions, GLE70 exhibited the strongest antioxidant and hepatoprotective effects. Integrated chemical characterization, network pharmacology, molecular docking, and in vivo validation suggested that GLE70 may exert

Protective Mechanism of Auricularia auricula Polysaccharides Against Acute Alcoholic Liver Injury Is Related to Different Consumption Doses

eFood, Volume 7, Issue 2, April 2026.
The study investigated the protective mechanisms of low‐, medium‐, and high‐dose Auricularia auricula polysaccharide (AAP) against acute alcoholic liver injury (AALI) by correlating hepatic biochemical indices with intestinal flora. ABSTRACT This study investigated the dose‐dependent protective effects of Auricularia auricula polysaccharides (AAP ...

Effects of Dendrobium Officinale Polysaccharides on Brain Inflammation of Epileptic Rats

International Journal of Polymer Science, 2019
Objective. To investigate the effects of Dendrobium officinale polysaccharides (DOPS) on the expression of inflammatory factors IL-1β and TNF-α and the MKP-1/MAPK signal pathway. Methods. PTZ-induced epileptic rat models were established. The rats were randomly divided into four groups: the control group, the DOPS group, the model group, and the DOPS ...

Guideline for the In Vivo Immunomodulatory Activity Test of Polysaccharide Based on Cyclophosphamide‐Induced Mouse Model

Food Safety and Health, Volume 4, Issue 2, Page 527-537, April 2026.
Abstract graph of the in vivo immunomodulatory activity of polysaccharide based on a cyclophosphamide‐induced mouse model. ABSTRACT The immune system serves as the primary defense mechanism against pathogens and plays a vital role in maintaining host homeostasis. In recent years, natural polysaccharides have emerged as promising immunomodulators due to
