Usage And Synthesis

Chemical Properties

Yellow crystalline powder, soluble in methanol, ethanol, DMSO and other organic solvents, from the leaves of Ailanthus, long-leaved arnica flowers, silver artemisia above ground, stevia, the leaves of the ground yellow, the above ground parts of the vine.

Uses

Jaceosidin exhibits anti-allergic, anti-inflammatory and apoptosis inducing activities.

Definition

ChEBI: A trihydroxyflavone that is flavone with hydroxy groups at positions 5, 7 and 4' and methoxy groups at positions 3' and 6. Isolated from Salvia tomentosa and Artemisia asiatica, it exhibits anti-allergic, anti-inflammatory and apo tosis inducing activties.

in vivo

Jaceosidin (10 and 20 mg/kg, p.o., once a day for 3 days) blocks carrageenan-induced increase in leukocyte number and protein levels in air pouch exudates in mice^[3].
Jaceosidin (10, 20 mg/kg, p.o.) suppresses COX-2 expression and NF-κB activation in mice^[3].
Jaceosidin (20 mg/kg, p.o. for 2 hours) reduces hind paw edema volume in rats^[3].

Animal Model:	5-week-old male BALB/c mice (23-26 g)^[3]
Dosage:	10 and 20 mg/kg
Administration:	P.O. once a day for 3 days
Result:	Decreased the volumes of exudates (inflammatory markers), cell number and protein levels. Inhibited TNF-α by 46.7% and 50.8%, IL-1β by 46.0% and 44.7%, and PGE2 by 21.7% and 16.9%, respectively, at 20 mg/kg. Blocked COX-2 expression and NF-κB activation.

Animal Model:	Male Sprague-Dawley rats (180-200 g)^[3]
Dosage:	20 mg/kg
Administration:	P.O., for 2 hour
Result:	Reduced hind paw edema volume by 27.1% at 1 h, and 24.0% at 2 h, respectively.
