Flower fragrance compounds were found to be produced from the precursor solution obtained from flower buds by crude enzyme prepared from the flowers at the opening stage. GC and GC-MS analyses showed the formation of volatile aroma constituents from the precursor solution of Jasminum polyanthum F, Jasminum sambac Ait, and Gardenia jasminoides E, but none in… (More)
Tobiko is produced as a by-product in the manufacture of konnyaku and comes to about 45% of dried konnyaku-imo. For a possible use of this powder, we studied its components. Serotonin, trans-N-(p-coumaroyl) serotonin, and a new compound, cis-N-(p-coumaroyl)serotonin, were characterized from this powder.
"Flow-through" anterior thigh flaps are used to reconstruct defects accompanied by major vessel damage in the extremities. These flaps have long flow-through pedicle vessels (which are the descending branch of the lateral circumflex femoral system) that can be interposed into the vascular gaps in the extremities and are composed anatomically of the rectus… (More)
The radial artery perforator-based adipofascial flap seems to be suitable for resurfacing defects on the dorsal hand. This flap is classified as one of the distally based intertendinous septocutaneous flaps, which are supplied by the dorsal superficial branch of the radial artery. The advantages of this flap are (1) surgery is minimal, of short duration,… (More)
Astaxanthin captured peroxynitrite to form nitroastaxanthins. 15-Nitroastaxanthin was a major reaction product of astaxanthin with peroxynitrite. Here, the anti-oxidative, anti-tumor-promoting, and anti-carcinogensis activities of 15-nitroastaxanthin were investigated. In addition to astaxanthin, 15-nitroastaxanthin showed excellent singlet oxygen quenching… (More)
AIMS To screen 16 isoflavonoids isolated from Erythrina variegata (Leguminosae) for their antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA). METHODS AND RESULTS The roots of E. variegata were macerated with acetone. The chloroform-soluble fraction of the residue was subjected to repeated silica gel column chromatography… (More)
A new erythrinan alkaloid, 8-oxo-alpha-erythroidine epoxide, was isolated from wood of Erythrina poeppigiana together with the five known compounds, 8-oxo-alpha-erythroidine, erystagallin C, alpinumisoflavone, erythrinin C and eryvarin A. Their structures were elucidated on the basis of spectroscopic evidence.
Five isoflavonoids, 7,4'-dihydroxy-2'-methoxy-8-(gamma,gamma-dimethylallyl)isoflav-3-ene, 4'-hydroxy-2'-methoxy-6",6"-dimethylpyran[2",3":7,8]isoflav-3-ene, 5,7,4'-trihydroxy-2'-methoxy-5'-(gamma,gamma-dimethylallyl)isoflavanone, 5,4'-dihydroxy-7,2'-dimethoxy-5'-(gamma,gamma-dimethylallyl)isoflavanone and… (More)
An arylbenzofuran, erypoegin F and four isoflavonoids, erypoegins G-J, together with six known compounds were isolated from the roots of Erythrina poeppigiana, and their structures were elucidated on the basis of spectroscopic evidence. Erypoegin F is a rare 2-arylbenzofuran possessing a formyl group from a natural source, and erypoegin I is the first… (More)
The phytochemical 2',4'-dihydroxy-8-gamma,gamma-dimethylallyl-2",2"-dimethylpyrano[5",6":6,7]isoflavanone (bidwillon B) was isolated from Erythrina variegata and its antibacterial properties against methicillin-resistant Staphylococcus aureus (MRSA) were investigated. Bidwillon B inhibited the growth of 12 MRSA strains at minimum inhibitory concentrations… (More)
