Two New Polyhydroxylated Sterols from Ruppia maritima

Natural Product Letters, 2001
Two new sterols have been isolated from the aquatic plant Ruppia maritima and their structures were established as (24R) ergosta-8,22-diene-3 beta,6 beta,7 alpha-triol (1) and (24R) ergosta-8(14),22-diene-3 beta,6 beta,7 alpha-triol (2) on the basis of spectroscopic analysis.

Effects of tributyltin (TBT) on the seagrass Ruppia maritima

Marine Pollution Bulletin, 2004
The effects of tributyltin (TBT) on the seagrass Ruppia maritima were studied in two growth experiments. Plants were sampled at stations in Odense Fjord and Lunkebugten, Denmark, and replanted in reference sediment without TBT, reference sediment spiked with TBT, and in impacted sediment sampled in the highly TBT contaminated (7-57 microg kg (-1) dw ...

Taxonomy of the genus Ruppia in China

Aquatic Botany, 2014
Abstract After a study of extensive herbarium material, collected in 20 localities in the coastal areas of China, it appears that the genus Ruppia is represented by three morphologically very distinct species, Ruppia brevipedunculata n. sp., Ruppia sinensis n. sp., and Ruppia megacarpa Mason.

A revision of the genus Ruppia (Potamogetonaceae) in Australia

Aquatic Botany, 1982
We conclude that Ruppia is best placed in the family Potamogetonaceae. Four species are recognised in Australia, R. tuberosa Davis and Tomlinson, R. maritima L., R. megacarpa R. Mason and R. polycarpa R. Mason. A key is to provide to the species. A lectotype is chosen for R. maritima and a neotype for R. tuberosa.
