Humulene Diepoxides from the Australian Arid Zone Herb Dysphania : Assignment of Aged Hops Constituents

Determination of antioxidant constituents in the herb Cissus quadrangularis Linn.

The herb Cissus quadrangularis Linn. has been widely used as antihemorrhoid preparations in Thailand. In order to establish the quality control procedures, both qualitatively and quantitatively determination of the antioxidant constituents of the herb were investigated by using the HPLC method. The antioxidant constituent of the plant was identified by the standard DPPH and ABTS methods, togeth...

Lupulon and Humulon-antibiotic Constituents of Hops.

Birth of a biome: insights into the assembly and maintenance of the Australian arid zone biota.

The integration of phylogenetics, phylogeography and palaeoenvironmental studies is providing major insights into the historical forces that have shaped the Earth's biomes. Yet our present view is biased towards arctic and temperate/tropical forest regions, with very little focus on the extensive arid regions of the planet. The Australian arid zone is one of the largest desert landform systems ...

Characterization of phenolic constituents from ephedra herb extract.

Nine known compounds: trans-cinnamic acid, catechin, syringin, epicatechin, symplocoside, kaempferol 3-O-rhamnoside 7-O-glucoside, isovitexin 2-O-rhamnoside, herbacetin 7-O-glucoside, and pollenitin B and a new flavonoid glycoside, characterized as herbacetin 7-O-neohesperidoside (1) on the basis of spectroscopic analysis and chemical evidence, were isolated from a traditional crude drug, "Ephe...
