A new 5-alkylresorcinol glucoside derivative from Cybianthus magnus
TLDR
One new 5-alkylresorcinol glucoside (1) was isolated from leaves of Cybianthus magnus, along with 12 known compounds, isolated from four plants belonging to Myrsinaceae family, determined on the basis of spectroscopic analysis and by comparison of their spectral data with those reported in the literature.
Biological activities of triterpenoids from Poraqueiba sericea stems
Abstract Eleven compounds were isolated from Poraqueiba sericea stems and identified as niga-ichigoside-F1 (1), trachelosperoside B1 (2), 4-epi-niga-ichigoside (7), 19α-hydroxyasiatic acid (3),
Zebiriosides A-L, oleanane saponins from the roots of Dendrobangia boliviana.
TLDR
Twelve oleanane saponins, zebiriosides A-L, were isolated from the roots of Dendrobangia boliviana Rusby together with two known sap onins, talunùmoside I and 3-O-β-d-glucuronopyranosyl serjanic acid, which showed cytotoxic, antileishmanial and hemolytic activities.
The genus Poraqueiba ( Icacinaceae ) is composed of three species : Poraqueiba sericea Tulp
Eleven compounds were isolated from Poraqueiba sericea stems and identified as niga-ichigoside-F1 (1), trachelosperoside B1 (2), 4-epiniga-ichigoside (7), 19α-hydroxyasiatic acid (3), myrianthic acid
New oleanane saponins from the roots of Dendrobangia boliviana identified by LC‐SPE‐NMR
TLDR
The joint use of LC and solid‐phase extraction (SPE) results in more concentrated samples and therefore improves the signal‐to‐noise ratio of NMR spectra achievable within a given period of time and appeared as a timesaving method with a broad application range.
Phytochemical study of four plants from the family Myrsinaceae
TLDR
Four Peruvian plants belonging to the Myrsinaceae family have been studied in search of molecules with antileishmanial activity and one new compound was isolated and identified as 5-alkylresorcinolglucoside, named Cybianthoside A (1).
