Ardisiaquinones from Ardisia teysmanniana

Phytochemistry, 2001
Bioassay-guided fractionation of a CHCl(3) extract from the leaves of Ardisia teysmanniana Scheff. (Myrsinaceae) has led to the isolation of three new alkyldibenzoquinone derivatives that showed inhibitory activity in an in vitro assay for UDP-MurNac synthesis.

ALLOZYME AND CLONAL DIVERSITY IN KOREAN POPULATIONS OF ARDISIA JAPONICA AND ARDISIA CRENATA (MYRSINACEAE)

Israel Journal of Plant Sciences, 2000
Using allozymes as genetic markers, genetic and genotypic diversity of Korean populations of Ardisia japonica and A. crenata, insect-pollinated and self-compatible subshrubs, were investigated to infer the establishment history of populations. Populations of the two species maintained low levels of all ozyme diversity (expected heterozygosity = 0.061 ...

Triterpenoid saponins from Ardisia mamillata

Phytochemistry, 2000
Two saponins were isolated from the roots of Ardisia mamillata HANCE. Their structures were established on the basis of MALDI-TOFMS, 1H, 13C NMR and 2D NMR (COSY, HOHAHA, HETCOR, HMBC and ROESY) spectra, and on chemical evidence, to be ardisimamilloside A, 3-O-[alpha-L-rhamnopyranosyl-(1 --> 2)-beta-D-glucopyranosyl-(1 --> 4)-[beta-D-glucopyranosyl-(1 -

Terpenoids from Ardisia squamulosa

Chemistry of Natural Compounds, 2013
The genus Ardisia Swartz belongs to the family Myrsinaceae. Ardisia has 68 recorded species in the Philippines [1], 60 of which are endemic. The hexane extract from A. squamulosa was reported to have a significant effect on sperm count but has a negligible effect on sperm morphology and viability [2]. No chemical study of A.
