Alkaloids from Spathelia excelsa: their chemosystematic significance.
The methanol extract from the leaves of Spathelia excelsa yielded six alkaloids: 2-(12-oxo-tridecanyl)-3-methoxy-4-quinolone, 2-(10-hydroxy-10-methyldodecanyl)-3-methoxy-4-quinolone, 2-(11-hydroxy-11-methyldodecanyl)-3-methoxy-4-quinolone, 2-(12-hydroxytridecanyl)-3-methoxy-4-quinolone, 7-hydroxy-2-(3-hydroxy-3-methylbutyl)-4-quinolone and 6-hydroxy-2-(3-hydroxy-3-methylbutyl)-4-quinolone, in a...
متن کاملSpathelia belizensis, a new species and first record for the genus in Central America (tribe Spathelieae, Rutaceae)
Spathelia L. as currently circumscribed is endemic to the western portion of the West Indies, and contains nine species, one endemic to the Bahamas, three endemic to Jamaica and five endemic to Cuba. The discovery of a new species in Belize brings the total number of species in Spathelia to ten and expands its known distribution beyond the West Indies. Spathelia belizensissp. nov. is herein des...
متن کاملTetranortriterpenoids and Dihydrocinnamic Acid Derivatives from Hortia colombiana
Dois tetranortriterpenos, sendo um inédito e dois novos derivados do acido dihidrocinâmico foram obtidos da madeira de Hortia colombiana. Suas estruturas foram elucidadas por RMN, e as configurações relativas estabelecidas através de experimentos de nOe diferencial. Em adição, foram isolados aloxantoxiletina, nerolidol, epoxinerolidol, três conhecidos derivados do acido dihidrocinâmico e duas a...
متن کاملNovel and Neuroprotective Tetranortriterpenoids from Chinese Mangrove Xylocarpus granatum Koenig
Eight new tetranortriterpenoids (1-8) were isolated from the twigs and leaves of the Chinese mangrove plant Xylocarpus granatum, together with four related known ones (9-12). The structures of new compounds were elucidated by detailed spectroscopic analysis. The absolute configuration of 9-epixylogranatin A (1) was determined by time-dependent density functional theory-electronic circular dichr...
متن کاملPhylogeny, evolutionary trends and classification of the Spathelia-Ptaeroxylon clade: morphological and molecular insights.
BACKGROUND AND AIMS The Spathelia-Ptaeroxylon clade is a group of morphologically diverse plants that have been classified together as a result of molecular phylogenetic studies. The clade is currently included in Rutaceae and recognized at a subfamilial level (Spathelioideae) despite the fact that most of its genera have traditionally been associated with other families and that there are no o...
