Zhongguo Zhong Yao Za Zhi. 2013 Jun;38(11):1735-9. | Isoprenylated phenolic compounds from leaves of Morus yunnanensis.[Pubmed: 24010287] | METHODS AND RESULTS: Phytochemical investigation on an EtOH extract of the leaves of Mons yunnanensis led to the isolation and characterization of 11 isoprenylated phenolic compounds, morusyunnansin G (1), morachalcone B (2), cudraxanthone M (3), Cudraxanthone D (4), sanggenofuran B(5), moracin D (6), moracin C (7), moracin I (8), demethylmoracin I (9), morachalcone A (10), and isobacachalcone (11).
CONCLUSIONS:
Compound 1 is a new compound and compounds 2-11 were isolated from this plant for the first time. | Planta Med. 1984 Jun;50(3):218-21. | Components of Root Bark of Cudrania tricuspidata l.1,2 Structures of Four New Isoprenylated Xanthones, Cudraxanthones A, B, C and D.[Pubmed: 17340300] |
METHODS AND RESULTS:
Four new isoprenylated xanthones, cudraxanthones A, B and C were isolated from the N-hexane extract of the root bark of CUDRANIA TRICUSPIDATA (Carr.) Bur. (Japanese name "Hariguwa"; Moraceae), and Cudraxanthone D from the benzene extract. The structures of cudraxanthones A, B, C and D were shown to be 1-4, respectively, on the basis of spectral and chemical evidence. |
