in this study, caffeic acid (ca) and its three derivatives including 3-caffeoylquinic acid (3-cqa, neochlorogenic acid), 4-caffeoylquinic acid (4-cqa, cryptochlorogenic acid), and 5-caffeoylquinic acid (5-cqa, chlorogenic acid) were identified in bupleurum chinense aerial parts using reverse-phase high-performance liquid chromatography (rp-hplc) with photodiode array (pda) detector, reference c...

Flavonoids distribution in three algerian Bupleureum (Apiaceae) species has been investigated. Quercetin (1), quercetin 3-rutinoside (2) and isorhamnetin 3-rutinoside (3) were found in the endemic species B. plantagineum Desf. Three kaempferol glycosides, kaempferol 3-glucoside (4), kaempferol 3-galactoside (5), kaempferol 3-rutinoside (6) and three quercetin glycosides, quercetin 3-rutinoside ...

This study demonstrated particle size effect on the measurement of saikosaponin A in Bupleurum chinense DC. by near infrared reflectance (NIR) spectroscopy. Four types of granularity were prepared including powder samples passed through 40-mesh, 65-mesh, 80-mesh, and 100-mesh sieve. Effects of granularity on NIR spectra were investigated, which showed to be wavelength dependent. NIR intensity w...

In the course of field research, analysis previously published works and review materials stored in well-known collection funds Siberia (NS, KRAS, SSHZ), information on distribution rare adventitious native plant species Upper Yenisei basin was clarified. For first time, Arctium lappa, Armoracia sisymbrioides, Bupleurum sibiricum, Calystegia sepium, Lolium perenne, Pastinaca sativa, Polygonum s...

-Three tetrahydrofuran lignans [l-3} were obtained from the leaves of Bupleu17lm salici!olium, of which busaliol {l} and busalicifol {2} are novel. Their structures were determined by spectral and chemical methods. Also obtained in this investigation were a number of other lignans, coumarins, a polyacetylene, and a triterpenoid, all of known structure. Bupleurum salicifolium Sol!. ex Lowe (Umbe...
