A preparative high-speed counter-current chromatography (HSCCC) method for isolation and purification of coumarin compounds from the Chinese medicinal plant Peucedanum decursivum (Miq.) Maxim (Zihuaqianhu in Chinese) was successfully established by using light petroleum-ethyl acetate-methanol-water (5:5:7:4, v/v) as the two-phase solvent system. The upper phase of light petroleum-ethyl acetate-...

BACKGROUND The root of Peucedanum japonicum Thunb., a perennial herb found in Japan, the Philippines, China, and Korea, is used as an analgesic. In a previous study, sec-O-glucosylhamaudol (SOG) showed an analgesic effect. This study was performed to examine the antinociceptive effect of intrathecal SOG in the formalin test. METHODS Male Sprague-Dawley rats were implanted with an intrathecal ...

Five species of the rock-climbing, gobiid subfamily Sicydiinae are now known from Ponape, Eastern Caroline Islands, Micronesia, four of which are described herein as new: Sicyopus nigriradialus, Sicyoplerus lividus, Sicyopterus eudenlatus, and Sliphodon caeruleus. This increases the number of described freshwater/estuarine fish species from that volcanic island to 15. The fifth sicydiine specie...

Six samples of Ss *ere tested with instrument which utilized a semantic differential format. The "concepts" v -2 "Americans in general tend to be" and "Greeks in general tend to be. The scales were characteristics obtained from unstructured interviews of Americans and Greeks woi 'ing together in jobs requiring face-to-face social relations. The six samples varied in the degree of contact. Maxim...

In this paper the notion of individual agency is critically examined in light of the enactive approach to understanding the mind. It is argued that following the work of Hanne De Jaegher, Ezequiel Di Paolo, Tom Froese and others, agency must be considered in terms that are situational rather than bounded by biological individuals. Such a revised notion of agency presents substantive challenges ...

Coumarins are the main bioactive compounds in Peucedanum praeruptorum Dunn, a common Chinese herbal medicine. Nevertheless, the genes involved in the biosynthesis of core structure of coumarin in P. praeruptorum have not been identified yet. 4-Coumarate: CoA ligase (4CL) catalyzes the formation of hydroxycinnamates CoA esters, and plays an essential role at the divergence point from general phe...
