OBJECTIVE
We have previously reported that the Australian Northern Kaanju (Kuuku I'yu) medicinal plant Dodonaea polyandra has anti-inflammatory activity. This is attributed largely to the presence of clerodane diterpenoids contained within the leaf resin. We envisaged developing a topical
The aim of this study was to identify an anti-inflammatory compound from D. viscosa leaves. The structure of this bioactive substance was elucidated by IR and NMR studies, which indicated that this natural product corresponds to hautriwaic acid (HA). This diterpene exhibited good anti-inflammatory
Dodonaea polyandra is a medicinal plant used traditionally by the Kuuku I'yu (Northern Kaanju) indigenous people of Cape York Peninsula, Australia. The most potent of the diterpenoids previously identified from this plant, polyandric acid A (1), has been examined for inhibition of pro-inflammatory
1. The metabolism of the anti-inflammatory diterpenoid polyandric acid A (PAA), a constituent of the Australian Aboriginal medicinal plant Dodonaea polyandra, and its de-esterified alcohol metabolite, hydrolysed polyandric acid A (PAAH) was studied in vitro using human liver microsomes (HLM) and
BACKGROUND
Extracts of the medicinal plant species Dodonaea polyandra were investigated as part of a collegial research partnership between Northern Kaanju traditional owners represented by Chuulangun Aboriginal Corporation (centred on the Wenlock and Pascoe Rivers, Cape York Peninsula, Queensland,
The crude extracts of the leaves of Dodonaea viscosa and Rumex nervosus as well as of the root of Rumex abyssinicus were tested for anti-microbial and anti-inflammatory activities. It was observed that the three plants possess antibacterial activity against Streptococcus pyogenes and Staphylococcus
Blood-brain barrier endothelial cells are the main targets of diabetes-related hyperglycemia that alters endothelial functions and brain homeostasis. Hyperglycemia-mediated oxidative stress may play a causal role. This study evaluated the protective effects of characterized polyphenol-rich medicinal
Dodonaea viscose, Linn is a widely grown plant of Nilgiris district of Tamil and is commonly used by the tribals of Nilgiris as a traditional medicine for done fracture and joint sprains. Since it is generally believed tat fractures are accompanied by either some degree of injury or inflammations,
Background-Medicinal plants are traditionally used as infusions or decoctions for their antioxidant, anti-inflammatory, hypolipidemic and anti-diabetic properties. Purpose-The aim of the study was to define the polyphenol composition and to assess the antioxidant capacity of eight medicinal plants
The hydroalcoholic extract (HAE) of the leaves of Dodonaea viscosa, given by oral route at dose of 300 mg/kg, significantly inhibited the paw edema induced by carrageenin injection. The extract did not show any sign of toxicity in mice up to 5000 mg/kg p.o. This result seems to support the use of D.
A new labdane diterpenoid, 2,18-dihydroxylabda-7,13(E)-dien-15-oic acid (1), together with two known labdane diterpenes (3, 4), a new flavone, 5,7-dihydroxy-3,6,4'-trimethoxy-3'-(4-hydroxy-3-methyl-but-2-enyl)flavone (2) with three known flavones (5-7) were isolated from the aerial parts of Dodonaea
Four new benzoyl ester clerodane diterpenoids, 15,16-epoxy-8α-(benzoyloxy)methylcleroda-3,13(16),14-trien-18-oic acid (1), 15,16-epoxy-8α-(benzoyloxy)methyl-2α-hydroxycleroda-3,13(16),14-trien-18-oic acid (2), 15,16-epoxy-8α-(benzoyloxy)methyl-2-oxocleroda-3,13(16),14-trien-18-oic acid (3), and
BACKGROUND
Oily substances extracted by a crude process from the stem including its bark (hereafter referred to as the stem) of Dodonaea viscosa (L.) Jacq. has been used by practitioners of traditional Indian medicine to treat inflammation, pain and other musculoskeletal disorders.
OBJECTIVE
The aim
In the present work, the antiarthritic activity of hautriwaic acid is reported. This ent-clerodane diterpene isolated from Dodonaea viscosa was evaluated in mice using a kaolin/carrageenan-induced monoarthritis model. The inflammation observed in the joint (knee) on days 1-8 ranged from 50-70 %.
Three prenylated flavonoids 5,7,4'-trihydroxy-3'(3-methylbut-2-enyl)-3-methoxy flavone, 5,7-dihydroxy-3'(3-methylbut-2-enyl)-3,4'-dimethoxy flavone and 5,7,4'-trihydroxy-3',5'(3-methylbuyt-2-enyl)-3-methoxy flavone together with three other known flavonoids were isolated from the medicinal plant
