magnolia officinalis/抗過敏

We studied the effect of aqueous extract of Magnolia officinalis bark (Magnoliaceae) (MOAE) on the immediate hypersensitivity reaction. MOAE (0.01 to 1 g/kg) dose-dependently inhibited compound 48/80 induced systemic anaphylaxis in rats. MOAE (0.1 and 1 g/kg) also significantly inhibited local

To define the anti-allergic components in Saiboku-To, a herbal medicine for bronchial asthma, we examined the effects of 11 compounds found in post-administrative urine of Saiboku-To on concanavalin A-induced human lymphocyte blastogenesis in vitro and picryl chloride (PC)-induced mouse ear swelling

The antiallergic effects of magnolol and honokiol, isolated from the bark of Magnolia obovata (family Magnoliaceae), were investigated both in vitro and in vivo. Magnolol and honokiol potently inhibited passive cutaneous anaphylaxis reactions in mice induced by IgE-antigen complex as well as

Four new lignans, a furofuran lignan medioresinol B (10) and three tetrahydrofuran lignans kobusinol C (16), 7'-methoxy magnostellin A (21), and mangnostellin D (23), along with 19 known lignans, were isolated from the flower buds of Magnolia biondii PAMP. The structures of the isolates were

Magnolia species have been used for the treatment of allergic diseases in Asia as folk medicine; however, the cellular and molecular mechanisms of its anti-allergic effects have rarely been investigated. In this study, we demonstrated that a methanolic extract of the fructus of Magnolia denudata has

BACKGROUND Magnolol, a compound isolated from the cortex of Magnolia officinalis, has been found to possess anti-allergic and anti-asthmatic activity. METHODS The effect of magnolol on ionic currents was studied in cultured smooth muscle cells of human trachea with the aid of the patch clamp

In order to establish the antiallergic properties of Schisandra fructus and Magnolia flos, several compounds isolated from these plants were tested for 5-lipoxygenase (5-LOX) inhibitory activity in vitro, for the first time. The compounds including schizandrins, schisandrols, gomisins, fargesin,
