Cypripedium tibeticum is a threatened orchid which efficient conservation requires knowledge of its extent and structure of genetic variation. Using two chloroplast DNA fragments(rps16 and trnL-F), we analyzed 157 ind...
Microsatellites, or simple sequence repeats (SSRs), are highly polymorphic, co-dominant genetic markers commonly used for population genetics analyses although de novo development of species specific microsatellites i...
A new phenanthraquinone, cypripediquinone A, was isolated from the rhizome of Cypripedium macranthum ( Orchidaceae ) and its structure was established as 2,4,7-trimethoxy-9, 10- phenanthraquinone mainly by spectroscop...
