It is suggested that further investigations on these bioactive compounds might be needed to discover and develop new antiviral agents. Expand
Endothelium-dependent and direct relaxation induced by ethyl acetate extract from Flos Chrysanthemi in rat thoracic aorta.
It is concluded that FCE induced both endothelium-dependent and -independent relaxation, whereas inhibition of voltage-dependent Ca2+ channel, receptor-operate Ca2- channel and activation of K(ATP) contribute in part to the endothelia-independent relaxation. Expand
Phytochemical Investigation and Cytotoxic Evaluation of the Components of the Medicinal Plant Ligularia atroviolacea
The preliminary taxonomy of this species was discussed, and the possible biogenesis of a dimer possessing a new noreremophilanoid type skeleton, 7, is presented in a preliminary form. Expand
A new dibenzofuran and other constituents from Ligularia caloxantha , a chinese medicinal plant
A new dibenz ofuran named 1,2,4-trimethyl-7,8-dimethoxy-dibenzofuran is isolated from the roots of Ligularia caloxantha, a Chinese medicinal plant by spectroscopic methods. Expand
[Studies on chemical constituents of green algae Ulva pertusa].
The alga was extracted with ethanol, isolated and purified by column chromatography on silica gel and sephadex LH -20 and all other compounds were isolated for the first time from U. pertusa, except for the compound 4. Expand
Simultaneous determination of three flavonoid aglycones in Elsholtzia blanda by adopting orthogonal test and high-performance liquid chromatography.
The optimum hydrolysis condition is relatively gentle, and the HPLC method is proved to be simple, accurate, and sensitive, so it will be able to be applied to quality control of medicinal plant of Elsholtzia blanda. Expand
Solubility of Camellianin A in Methanol, Acetonitrile, Acetone, and Water from (283.2 to 313.2) K
The solubility of camellianin A (4′,5,7-trihydroxyflavone; 5-O-[α-l-rhamnopyranosyl-(1→4)-6-O-acetyl-β-d-gluco-pyranoside]) in methanol, acetonitrile, acetone, and water from (283.2 to 313.2) K wasExpand
