Studies on the constituents of the cultivated mulberry tree. II. Photo-oxidative cyclization of morusin.

Antioxidant and hepatoprotective activities of Egyptian moraceous plants against carbon tetrachloride-induced oxidative stress and liver damage in rats

“…White mulberry leaf contains triterpenes (lupeol), sterols (β-sitosterol), bioflavonoids (rutin, moracetin, quercetin-3-triglucoside, and isoquercitrin), coumarins, volatile oil, alkaloids, amino acids, and organic acids (Doi et al, 2001). On the other hand, the antioxidant potency of some phenolic compounds (flavonoids, stilbenes, and 2-arylbenzofurans) from Morus alba has been reported (Nomura et al, 1977(Nomura et al, , 1980Fukai & Nomura, 1998;Sharma et al, 2001;Jin et al, 2002;Fukai et al, 2003). The present study was therefore undertaken to evaluate the hepatoprotective activity of both Ficus carica (fruit and leaf ) and Morus alba (root bark) extracts.…”

Phenolic Compounds of the Mulberry Tree and Related Plants

“…In the course of our examination the constituents of the Morus root bark, we met with a novel photo-oxidative cyclization (41) to which reference has already been made in Section 11.2, when a solution of morusin (24) in chloroform was irradiated using a high-pressure mercury lamp or a tungsten lamp, morusin hydroperoxide (49), mp 204-206 °C, C2sH240s, was obtained in ca. 80% yield.…”

Hypotriglyceridemic effect of Morus alba L., Moraceae, leaves in hyperlipidemic rats

“…Leaves of Morus alba L. were subject to qualitative phytochemical investigation of the phytoconstituents anthocyanins, prenyflavons, flavonoids, stillbenes, 2-arylbenzofurans, carbohydrates, alkaloid and glycoproteins (Yagi et al, 1976;Nomura et al, 1977;Nomura et al, 1980;Hikino et al, 1985;Gerasopoulos & Stavorulakis, 1997;Fukai & Nomura, 1998;Kim et al, by comparing with the voucher specimen number 2564 located at Herbário Dr. Miguel Pedro Klein of Universidade Regional de Blumenau (FURB).…”
