"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)
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.
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)
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)
Six phytochemicals were isolated from the roots of Erythrina zeyheri (Leguminosae) by repeated silica gel column chromatography using various eluting solvents. Extensive spectroscopic studies revealed that all were isoflavonoids. The antibacterial activity of the six compounds against vancomycin-resistant enterococci (VRE) was estimated by determining the… (More)
We isolated the highly potent attachment-inhibitors (three times more active than standard CuSO4 in the blue mussel assay), trans-6-, 8-, and 10-shogaols, from a hexane extract of the roots of ginger, Zingiber officinale Roscoe. Trans-8-shogaol showed the highest antifouling activity comparable with that of tributyltin fluoride (TBTF), which is recognized… (More)
Five isoflavonoids, (+/-)-7,2',4'-trihydroxy-8,3'-di(gamma,gamma-dimethylallyl)isoflavanone, (3R)-7,4'-dihydroxy-2'-methoxy-6,8-di(gamma,gamma-dimethylallyl)isoflavanone, (3R)-7,2',4'-trihydroxy-6,8-di(gamma,gamma-dimethylallyl)isoflavan, 2',4'-dihydroxy-8-gamma,gamma-dimethylallyl-2",2"-dimethylpyrano-[5,6:6,7]isoflavan and (6aS,… (More)
Four isoflavonoids, erysubins C-F, together with ten known compounds were isolated from the roots of Erythrina suberosa var. glabrescences, and their structures were elucidated on the basis of spectroscopic evidence. Erysubin C is an unusual pterocarpan derivative with a formyl group.
Five phenolic compounds, p-hydroxyacetophenone, 5,7-dihydroxychromone, naringenin, quercetin, and iso-americanol A, were found first time in the barley tea, together with the known compounds, p-hydroxybenzaldehyde, 3,4-dihydroxybenzaldehyde, p-hydroxybenzoic acid, vanillic acid, and p-coumaric acid. The anti-oxidative properties were evaluated by measuring… (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.
