原始语种摘要: Abstract From the leaves of Chamaecyparis obtusa several biflavones were isolated and identified, namely: sciadopitysin, ginkgetin, isoginkgetin, podocarpusflavone B, 7,7″-O-dimethylamentoflavone, bilobetin, podocarpusflavone A, and 7-O-methylamentoflavone. The presence of amentoflavone and hinokiflavone was also confirmed. The composition of biflavones in other Chamaecyparis species D Ch. lawsoniana, Ch. thyoides D and cultivar varieties D Ch. pisifera “Squarrosa”, Ch. pisifera “Boulevard” D was compared using the HPLC method. It was stated, that podocarpusflavone A and 7-O-methylamentoflavone in addition to amentoflavone and hinokiflavone may be classified as chemotaxonomic markers of the genus Chamaecyparis
