The stems of Fissistigma polyanthoides (A.DC.) Merr. are traditionally used for the treatment of rheumatism and for recuperating women after childbirth. In our continuous phytochemical investigation of this plant, four new (1, 2, 5, and 19) and fifteen known (3, 4, and 6-18) phenolic compounds were
BACKGROUND
Fissistigma polyanthum is a liane belonging to the Annonaceae family and it is one of the most important crude drugs in traditional Chinese medicine.
OBJECTIVE
The objective was to describe the structural elucidation and the free-radical-scavenging activities of the isolated compounds
OBJECTIVE
To optimize the extraction and purification techniques of total flavonoids in Fissistigma oldhamii. The scavenging activity to DPPH of the total flavonoids and the extraction were studied in vitro.
METHODS
By orthogonal design, we investigated the effects of concentration of ethanol,
Three new flavonol glycosides, fissflavosides A-C (1-3), together with six known flavonol glycosides, kaempferol 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-galactopyranoside (4), kaempferol 3-O-α-L-rhamnopyranosyl-(1→6)-β-D-galactopyranoside (5), kaempferol
