Stir-baked Fructus gardeniae (L.) extracts inhibit matrix metalloproteinases and alter cell morphology.

Effects of oral administration of Gardeniae fructus extract and intravenous injection of crocetin on lipopolysaccharide- and prostaglandin E2-induced elevation of aqueous flare in pigmented rabbits.

The purpose of this study was to evaluate the effects of extracts of Coptidis rhizoma, Phellodendri cortex and Gardeniae fructus, which are medicinal herbs in Orengedoku-to (Huanglin-Jie-Du-Tang in Chinese), and crocetin (a major component of Gardeniae fructus) on experimental elevation of aqueous flare in pigmented rabbits. To produce aqueous flare elevation, 0.5 microg/kg lipopolysaccharide (...

Changing Roles of Matrix Metalloproteases and Their Inhibitors, TIMPs, During Tumor Progression and Angiogenesis

Inhibition of matrix-metalloproteinases (MMPs) by tissue inhibitors of metalloproteinases (TIMPs) has been shown in vivo to decrease metastasis and tumor-associated angiogenesis. Our laboratory is interested in understanding the role of these proteins at the pericellular microenvironment of tumor and endothelial cells. Secretion of MMPs by tumor cells enables the migration, invasion and metasta...

Pharmacokinetic Evaluation of Clozapine in Concomitant Use of Radix Rehmanniae, Fructus Schisandrae, Radix Bupleuri, or Fructus Gardeniae in Rats.

Radix Rehmanniae, Fructus Schisandrae, Radix Bupleuri, and Fructus Gardeniae are often used alongside with clozapine (CLZ) for schizophrenia patients in order to reduce side effects and enhance therapeutic efficacy. However, worse outcomes were observed raising concern about a critical issue, herb-drug interactions, which were rarely reported when antipsychotics were included. This study aims t...

Studies of the constituents of Gardenia species. II. Terpenoids from Gardeniae Fructus.

Four new terpenoids, gardenate A (1), 2-hydroxyethyl gardenamide A (2), (1R,7R,8S,10R)-7,8,11-trihydroxyguai-4-en-3-one 8-O-beta-D-glucopyranoside (3) and Jasminoside F (4), were isolated from Gardeniae Fructus. Their structures were established on the basis of spectral analysis.

3-Caffeoyl-4-sinapoylquinic acid, a novel lipoxygenase inhibitor from Gardeniae fructus.
