TL;DR: The findings demonstrated that the purified polysaccharide from D. officinale presented significant immune-modulating activities and that the signaling pathways of DOP-1-1 induced immune activities involving ERK1/2 and NF-кB.

TL;DR: In vivo assays showed that D. officinale polysaccharides (DOPs) exerted significant hypoglycemic effects accompanying increased serum insulin and glucagon-like peptide-1 levels in streptozotocin-induced diabetic rats, and in vitro experiments indicated that DOPs may decrease fasting blood sugar levels by stimulating GLP-1 secretion and that intracellular DOP-induced GLPs involved the Ca2+/calmodulin/CaMKII and

TL;DR: The present study was the first one to demonstrate the gastroprotective effect of DOP through inhibiting oxidative stress-induced apoptosis and provided a solid evidence for the potential use of DO as a therapy or health supplement for gastric mucosal diseases.

TL;DR: Investigation of the 95% EtOH extract of stems of Dendrobium findlayanum afforded four new seco-dendrobines, findlayines A-D (1-4) and four new phenolic compounds, dendrofindlaphenols A-C (7, 9, and 10) and 6″-de-O-methyldendro findlaphenol A (8).

TL;DR: Three new iridoids, jatamanvaltrates R-S and Jatamanin Q, as well as three new sesquiterpenoids, valeriananoids D-E and clovane-2β-isovaleroxy-9α-ol, together with nine known compounds were isolated from the roots of Valeriana jatamansi Jones.
