Triterpenoids ofDiospyros lotus

Abstract

The following triterpenoids have been found in various species of Diospyros (persimmon), which is widely used in the folk medicine of India: lupeol, betulin, hydroxyallobetulin, betulinic acid, bauerenol, a-amyrin, taraxerol, and oleanolic and ursolic acids [1][2][3][4][5]. Taraxerol, hydroxyallobetulin, and betulinic acid have been found in Diospyros lotus L. growing in Japan [6].We have investigated the triterpene composition of the bark of Diospyros lotus L. collected in the Azerbaidzhan SSR close to Lenkoran'. From a chloroform extract of the bark we isolated taraxerol , taraxerone, B-amyrin, betulinic acid, and the acetate of ursolic acid. For identification we obtained by the usual methods derivatives of these compounds which had melting points agreeing with those given in the literature.

Diospyros lotus L. fruit extract protects G6PD-deficient erythrocytes from hemolytic injury in vitro and in vivo: prevention of favism disorder

“…The value of IC50 in this study was similar to the IC50 obtained in our study. Another study on the phytochemical investigation of the Diospyros lotus L. plant revealed the presence of some fatty acids and nonvolatile acids in the fruit 37 , total phenol and flavonoid content 38 , terpenes 39 and naphthoquinones 40 . In a study conducted by Said et al 41 , eight phenolic compounds were isolated and identified as gallic acid, methylgallate, ellagic acid, kempferol, quercetin, myricetin, myricetin 3-O-β-glucuronide and myricetin 3-O-α-rhamnoside.…”
