New guaiane, megastigmane and eudesmane-type sesquiterpenoids and anti-inflammatory constituents from Youngia japonica.
Eleven sesquiterpenoids have been isolated from the whole plants of Youngia japonica (Asteraceae). Among these sesquiterpenoids, five were identified as new compounds on the basis of spectroscopic methods and chemical analysis. Their structures were 3-oxo-8alpha-(4-hydoxyphenyl)acetoxy-10(14),11(13)-guaiadien-12,6-olide ( 1), 3beta-[3-(4-hydroxyphenyl)acetyl-beta- D-glucopyranosyloxy]-8alpha-hy...
متن کاملFunctional behavior of tortoise hemoglobin Geochelone denticulata.
The hemolysate from Geochelone denticulata contains two main hemoglobin components, as shown by ion exchange chromatography and polyacrylamide gel electrophoresis (PAGE). Electrophoresis under dissociating conditions showed three types of globin chains. The apparent molecular mass, as determined by gel filtration on Sephadex G-200, was compatible with tetrameric Hb, which was unable to polymeri...

Maca (Lepidium meyenii Walpers) is a plant cultivated in central Peru, and its root is a common active ingredient in the botanical dietary supplements for its effects on a variety of health issues such as sexual dysfunction, anemia, and cancer. The plant contains compounds that have cytotoxic and antioxidant activities, but information on the metabolism of the bioactive compounds is limited. Th...
متن کاملStudies on cerebrospinal fluid. I. Quantitative fractionation of carbohydrate constituents.
Few quantitative data are available on the organic constituents of the cerebrospinal fluid (1). Preliminary to studies on the biosynthetic origins and functional significance of the glycoproteins of cerebrospinal fluid it was desirable to develop analytical methods applicable to small individual samples of this fluid. The development of such methods is made difficult because of the relatively l...
متن کاملStudies on the gonococcus: I. Constituents of the cell.
Progress in biochemical research on the gonococcus has not kept pace with that on other pathogenic microorganisms of similar importance. Reasons for this are twofold: gonococcal infection comparable to that in man cannot be reproduced experimentally in animals and the organism is difficult to grow in sufficient quantities to permit chemical study. For the latter reason, few of the cellular cons...
