Incazelo emfushane:

I-Fraxetin, eyaziwa nangokuthi i-Qinpi Pavilion;I-Ash tree lactone.Kuyisidakamizwa sokwelashwa kwe-acute bacillary dysentery ezinganeni.

Igama lesiShayina:i-fraxetin;

Isibizo:I-Qinpi Pavilion;I-Fraxinus lactone,

I-Melting Point:228 ℃


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Isifinyezo

Isibizo:I-Qinpi Pavilion;I-Fraxinus lactone

Igama lesiNgisi:i-fraxetin;i-fraxetol

Kungokwezinhlanganisela ze-coumarin.I-flake crystal (ethanol), indawo encibilikayo engu-228 ℃, iphenduka ibe phuzi ngo-150 ℃, futhi ibe nsundu lapho incibilika.Kuyi-hydrolyzate ye-aesculin, encibilika ku-ethanol ne-hydrochloric acid aqueous solution, inyibilika kancane emanzini abilayo futhi engancibiliki ku-ether.

Iphuma ku-Fraxinus brngeana DC Bark, amaqabunga odonga lwe-F. floribunda, njll.

Inomphumela we-anti-dysentery bacilli futhi ngokomtholampilo isetshenziselwa ukwelapha isifo sohudo esiyingozi ezinganeni.

Imikhiqizo ihlinzeka nge-fraxetin: Qinpi Pavilion
