A New Acylated Flavonoid from Anaphalis aureo-punctata

A new acylated flavonoid glycoside,3-O-kaempferol-3-O-acetyl-6-O-(p-coumaroyl)-β-D-glucopyranoside 1 was isolated from the whole plant of Anaphalis aureo-punetata.The structure was established by spectral methods.     

Phenolic compounds from Filipendula ulmaria

A chromatographically inseparable crystalline mixture of the previously undescribed quercetin-4′-O-β-galactopyranoside and the known quercetin-3-O-β-glucopyranoside (isoquercitrin) in a 7:5 ratio was isolated from the extract of the aerial part of Filipendula ulmaria (L.)

A New Furobenzopyranone from Anaphalis lactea

A new furobenzopyranone, named anaphalisol, was isolated from the whole plant of Anaphalis lactea. Its structure was elucidated by spectroscopic methods including 2D NMR techniques.     

Phenolic compounds of sumac

The main component of the polyphenolic complex has been isolated from the leaves of two species of sumac (Rhus glabra andRh. typhina) and for this we have proposed the structure of 3,6-bis-O-digalloyl-1,2,4-tri-O-galloyl--D-glucose. A high interferon-inducing and antitumoral activity of the substance isolated has been found. In addition to catechins, 3,4,6-trihydroxyaurone has been tisolated from sumac stems.A. S.
