Ethyl Rosmarinate Protects High Glucose-Induced Injury in Human Endothelial Cells.

Ethyl rosmarinate (RAE) is one of the active constituents from (Benth.) O. Kuntze, which is used for diabetic treatment in Chinese folk medicine.

Apigenin and naringenin ameliorate PKCβII-associated endothelial dysfunction via regulating ROS/caspase-3 and NO pathway in endothelial cells exposed to high glucose.

Endothelial dysfunction is a key event in the progression of atherosclerosis with diabetes. Increasing cell apoptosis may lead to endothelial dysfunction. Apigenin and naringenin are two kinds of widely used flavones.

A new triterpenoid saponin from Clinopodium chinense (Benth.) O. Kuntze.

A new triterpene saponin, 3β,16β,23α,28β,30β-pentahydroxyl-olean-11,13(18)-dien-3β-yl-[β-D-glucopyranosyl-(1→2)]-[β-D-glucopyranosyl-(1→3)]-β-D-fucopyranoside, was named Clinoposaponin D (1), together with six known triterpene saponins, buddlejasaponin IVb (2), buddlejasaponin IVa (3), buddlejasaponin IV (4), clinopodisides D (5), 11α,16β,23,28-Tetrahydroxyolean-12-en-3β-yl-[β-D-glucopyranosyl-(1→2)]-[β-D-glucopyranosyl-(1→3)]-β-D-fucopyranoside (6) and prosaikogenin A (7), and two known triterpenes, saikogenin A (8) and saikogenin F (9) were isolated from Clinopodium chinense (Benth.) O. Kuntze.

Homoplantaginin Inhibits Palmitic Acid-induced Endothelial Cells Inflammation by Suppressing TLR4 and NLRP3 Inflammasome.

Palmitic acid (PA)-induced vascular endothelial inflammation plays a pivotal role in the occurrence and development of vascular diseases. The present study was conducted to examine the effect of homoplantaginin, a main flavonoid from a traditional Chinese medicine Salvia plebeia R. Br.

Diterpenoids from Saliva plebeia R. Br. and Their Antioxidant and Anti-Inflammatory Activities.

A new skeleton of diterpenoid, 1,2,3,4,4α,9,10,10α-octahydro-(4α-hydroxyymethyl) -1,1-dimethyl-9-(1-methylethyl)-(2S,3S,4αR,9R,10αS)-2,3,5,7-phenanthrenetertrol, named plebeianiol A (1), along with four known diterpenoids (2-5), were isolated from Salvia plebeia R. Br. Their structures were determined on the basis of spectral analysis.
