Isolation and structure of macarangonol, a diterpene ketol from Macaranga tanarius

Schweinfurthins A–Q: isolation, synthesis, and biochemical properties

“…A number of different classes of compounds such as prenylated stilbenes, geranylated avonols, prenylated avanones, chro-menoavones and diterpenes have been isolated from this species. [33][34][35][36] Schweinfurthins A-D were rst isolated by Beutler et al as yellowish solids from a mixed CH 2 Cl 2 -MeOH extract of M. schweinfurthii. 27,28 Another unexplored species of the Macaranga…”

Okinawan Subtropical Plants as a Promising Resource for Novel Chemical Treasury

“…Microtropis japonica HALLIER f. (Celastraceae) is an evergreen tree of about 5 m in height, and distributed in restricted areas such as southern part of Kanto, Kyushu, and Okinawa Islands in Japan and Taiwan. 6) Constituents of the EtOAc-soluble fraction of the stems and roots of M. japonica have been reported [7][8][9] including sesquiterpenoids (1-15), triterpenoids (16-23), lignans (24-26), and other phenolic compounds (27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37) (Fig. 1).…”

MACARANGIN, A GERANYLATED FLAVONOID AND ANTICANCER ACTIVE COMPOUND ISOLATED FROM ETHYL ACETAT FRACTION OF Macaranga gigantifolia LEAVES

“…There are more than 308 species of Macaranga, wide-spread from Africa and west region of Madagascar until tropical region of Asia, North Australia and east region of Pacific Islands (Blattner, 2001). Macaranga genus also known as a sources of terpenoid (Hui, 1971)] and phenolic (flavonoid) (Jang, 2002;Schutz, 1995;Sutthivaiyakit, 2002;Yoder, 2007) compounds which have biological activity as antioxidant (Phommart, 2005) and anticancer (cytotoxicity) (Yoder, 2007). Macarangin, a geranylated flavonoid compound is one of the flavonoid typical compounds contained in Macaranga genus, and have been isolated from M. vedeliana (Hnawia, 1990) and M. denticulate (Sutthivaiyakit, 2002).…”
