A new 2-arylbenzofuran derivative, (+)-dimethylsmoracin O (1), and three new Diels-Alder type adducts, mesozygins A–C (2–4), in addition to eight known compounds, artonin I (5), chalcomaracin (6), norartocarpetin (7), moracin L (8), mulberrofuran F (9), moracin M (10), moracin C (11), and
The investigation on the leaves of Morus alba L. was carried out to find the relationship of the constituents and the pharmacological activities. The isolation and purification were performed by various chromatographies such as silica gel, Sephadex LH-20, RP-C18 column chromatography and so on.
The column chromatography on silica gel, Sephadex LH-20 and semi-preparative HPLC were used to separate and purify the compounds from the EtOAc extract of medium and MeOH extract of cell cultures of Morus alba. Eight compounds were isolated. Based on physico-chemical properties and spectroscopic
A new 2-arylbenzofuran derivative, mornigrol D (1), along with two new flavones, mornigrol G (2) and mornigrol H (3), and six known compounds, norartocarpetin (4), dihydrokaempferol (5), albanin A (6), albanin E (7), moracin M (8), and albafuran C (9), were isolated from the barks of Morus nigra.
Five flavones displaying tyrosinase inhibitory activity were isolated from the stem barks of Morus lhou (S.) Koidz., a cultivated edible plant. The isolated compounds were identified as mormin (1), cyclomorusin (2), morusin (3), kuwanon C (4), and norartocarpetin (5). Mormin (1) was characterized as
The antiproliferative activities of 2',3,4',5,5'-pentahydroxy-cis-stilbene 1, resveratrol 2, oxyresveratrol 3, norartocarpetin 4, kuwanon C 5, morusin 6, cudraflavone A7, kuwanon G 8, albafuran C 9, mulberrofuran G 10, 3-acetyl-O-α-amyrin 11, 3-acetyl-O-β-amyrin 12, ursolic acid-3-O-acetate 13 and
A new stilbene, 2',3,4',5,5'-pentahydroxy-cis-stilbene (1), along with 13 known compounds, resveratrol (2), oxyresveratrol (3), norartocarpetin (4), kuwanon C (5), morusin (6), cudraflavone A (7), kuwanon G (8), albafurane C (9), mulberrofuran G (10), 3-O-acetyl-α-amyrin (11), 3-O-acetyl-β-amyrin
