Flavonoids from the leaves and stems of Dodonaea polyandra: A Northern Kaanju medicinal plant

Learning from Both Sides: Experiences and Opportunities in the Investigation of Australian Aboriginal Medicinal Plants

“…It could not be ruled out that other constituents within D. polyandra might be playing a supportive role for the observed antiinflammatory activity either through some additive anti-inflammatory effects or through effects on the distribution or clearance of the active diterpenoid compounds. Additional chemical analyses undertaken of 'less-active' fractions revealed the presence of a number of prenylated and non-prenylated flavonoids (53). Interestingly, a kaempferol derivative isolated in that study has been previously reported as an inhibitor of carrageenan-induced hind paw oedema and shown to be a potent anti-nociceptive agent in mice (54).…”

Vistriterpenoids A and B, Two New 24‐Nor‐oleanane Triterpenoids from Dodonaea viscosa

“…The structure of 1 was determined on the basis of the HMBC data ( Figure 2). The HMBCs of CH 2 (2)/C (1,3), CH 2 (7)/C (5,6,8,9), Me(23)/C (3,4,5,6), and Me (25)/C (1,5,9,10) built the A and B ring moieties with a Δ 4 double bond, an OH at C(3), and a carbonyl group at C (6). The HMBCs of HÀ C(12)/C (9,11,18), Me (26)/C (8,9,14), Me(27)/C (13,14,15), and Me(28)/C (16,17,18,22) indicated the C and D rings, a double bond being formed at C(12) and C (13).…”

“…[1] In China, D. viscosa is not only used as a wind-preventing and sand-fixing plant but also applied as a herbal medicine to treat empyrosis, stranguria, toothache, and skin diseases. [2] Diterpenoids, [3] flavonoids, [4] and saponins [5] isolated from this genus have been reported previously. Our recent research showed that clerodane diterpenoids and flavonoids were the main constituents of D. viscosa growing in Xishuangbanna, Yunnan Province, P. R. China.…”

New Alkaloids and α‐Glucosidase Inhibitory Flavonoids from Ficus hispida

“…The 12 known compounds were identified as 1‐(4‐hydroxyphenyl)‐2‐(2‐pyrrolidinyl)ethanone ( 5 ) , 5,7,4′‐trihydroxy‐3‐methoxy‐3′‐(3‐methylbut‐2‐en‐1‐yl)flavone ( 6 ) , carpachromene ( 7 ) , isoderrone ( 8 ) , ficuisoflavone ( 9 ) , isowighteone ( 10 ) , 3′‐(3‐methylbut‐2‐en‐1‐yl)biochanin A ( 11 ) , myrsininone A ( 12 ) , ficusin A ( 13 ) , 4′,5,7‐trihydroxy‐6‐[(1 R *,6 R *)‐3‐methyl‐6‐(1‐methylethenyl)cyclohex‐2‐en‐1‐yl]isoflavone ( 14 ) , lupiwighteone ( 15 ) , and mallotus A ( 16 ) , respectively, by comparing their spectroscopic data with those reported.…”
