The subtle colouring is pleasing, the bright green leaves with their silvery undersides blending well with the soft colouring of the neat, rounded heads of yellow or greenish yellow flowers. Old tangled bushes may be cut down in spring to regenerate.
A detailed phytochemical study of the aerial parts of Bupleurum marginatum Wall. ex DC revealed a novel aryltetraline lactone lignan identified as 9-(benzo[d][1,3]dioxol-5-yl)-6,7,8-trimethoxy-3a,4,9,9a-tetrahydronaphtho[2,3-c]furan-1(3H)-one (marginatoxin) along with nine known compounds and characterization of five other compounds either by GLC/MS or LC/MS techniques.
