Five new synonyms in Chinese Epimedium are designated in the present paper. Epimediumchlorandrum is treated as a synonym of Epimediumacuminatum; Epimediumrhizomatosum as a synonym of Epimediummembranaceum; Epimediumbrachyrrhizum as a synonym of Epimediumleptorrhizum; Epimediumdewuense as a synonym of Epimediumdolichostemon; and Epimediumsagittatumvar.oblongifoliolatum as a synonym of Epimediumb...

The Coptis chinensis Franch. is an important medicinal plant from the Ranunculales. We used next generation sequencing technology to determine the complete chloroplast genome of C. chinensis. This genome is 155,484 bp long with 38.17% GC content. Two 26,758 bp long inverted repeats separated the genome into a typical quadripartite structure. The C. chinensis chloroplast genome consists of 128 g...

Eriophyoid mites from Qinghai Province, northwestern China were studied herein. Up to now, only six species have been reported from Qinghai Province. In field surveys, 17 eriophyoid mite species were collected, among which nine species were found new to science. The new species and their host plants are listed as follows: Acaphyllisa tuberculumaesp. n. on Populus sp. (Salicaceae); Proiectus xin...

the isolation and characterization of two new isoquinoline alkaloids, dehydropuntarenine and dehydrosaulatine, obtained during the column chromatography of an alkaloidal fraction from the roots of b. actinacantha (berberidaceae) are described.

a novel c-homoprotoberberine alkaloid, hediamine (2), has been isolated from the roots of berberis actinucantha (berberidaceae). conclusive proof for the structure of hediamine was obtained by its comparison with the isomeric lactam (4), by chemical transformation, and by means of spectroscopic techniques (uv, ir, ms, nmr).
