The effects of 3-(4'-hydroxyl-3',5'-dimethoxyphenyl)propionic acid (HDMPPA) originating from Korean cabbage kimchi were investigated, showing an antioxidant effect on the prevention of atherosclerosis in hypercholesterolemic rabbits. Twenty-one 3-month-old rabbits were fed an atherogenic diet containing 0.5% (w/w) cholesterol and 10% (w/w) coconut oil,(More)
BACKGROUND Adverse events (AEs) derived from nonspecific activity of treatments can impair the validity of trials, and even make it difficult to identify specific AEs associated with treatments. To better understand these nonspecific AEs, we investigated the AEs in placebo groups by using knee osteoarthritis clinical trials. METHODS Randomized,(More)
OBJECTIVE To investigate the nocebo effect using randomized acupuncture trials that include sham and no-treatment groups. STUDY DESIGN AND SETTING Electronic databases were searched to retrieve eligible trials from their inception until June 2013. Risk differences were then calculated using the acupuncture and sham groups to determine the treatment effect(More)
Repeated chromatography of the EtOAc-soluble fraction from the 70% EtOH extract of the flower buds of Syzygium aromaticum (clove) led to the isolation and characterization of four new flavonol glucuronides, rhamnetin-3-O-β-d-glucuronide (1), rhamnazin-3-O-β-d-glucuronide (2), rhamnazin-3-O-β-d-glucuronide-6″-methyl ester (3), and(More)
Four new dibenzocyclooctadiene lignan glucosides, schisandrosides A-D (1-4), as well as two known rare nortriterpenoids, micrandilactone C (5) and propindilactone Q (6), were isolated from the roots of Schisandra chinensis BAILLON (Schisandraceae). The structure of compounds 1-4 were elucidated by physical and spectroscopic data interpretation. To the best(More)
The present investigation of the chemical constituents of the stem barks of Ailanthus altissima has resulted in the isolation of six canthinone-type alkaloids, including a new compound, (R)-5-(1-hydroxyethyl)-canthine-6-one (1), and five known compounds (2-6). Moreover, four phenyl propanoids (7-10), two lignans (11 and 12), two triterpenoids (13 and 14)(More)
