Twelve known triterpenoids (1-12) and two steroids (13 and 14) have been isolated from the spike of the plant Prunella vulgaris. Among them, 2α,3α,23-trihydroxyursa-12,20(30)-dien-28-oic acid (10) was isolated for the first time from this plant. All isolates were evaluated for their inhibitory
In this study, we investigated the effect of aqueous extract of Prunella vulgaris (Labiatae; PVAE) on the mast cell-mediated allergy model. We found that PVAE (0.001-0.1 g/kg) dose dependently inhibited compound 48/80-induced systemic anaphylaxis and serum histamine release in mice. PVAE decreased
We studied the effect of aqueous extract of Prunella vulgaris (Labiatae) (PVAE) on immediate-type allergic reactions. PVAE (0.005 to 1 g/kg) dose-dependently inhibited systemic anaphylactic shock induced by compound 48/ 80 in rats. When PVAE was given as pretreatment, at concentrations ranging from
The activity-guided fractionation of the extract of the herb of Prunella vulgaris (Labiatae) led to the isolation of four triterpenes, i.e., betulinic acid, ursolic acid, 2 alpha,3 alpha-dihydroxyurs-12-en-28-oic acid, and 2 alpha-hydroxyursolic acid. One of these compounds, 2 alpha,3
BACKGROUND
The Chinese term "Hot Qi" is often used by parents to describe symptoms in their children. The current study was carried out to estimate the prevalence of using the Chinese term "Hot Qi" to describe symptoms in children by their parents and the symptomatology of "Hot Qi".
METHODS
A cross
