Lespedeza cuneata

The role of plants has emerged from studies with soil slurries at a site with a cover of Paspalum notatum, Lespedeza cuneata, Solidago sp., and Pinus taeda in which increased degradation of trichloroethene to CO2 took place (Walton and Anderson 1990). In addition, prairie grasses can stimulate the effective remediation of PAH-contaminated soil (Aprill and Sims 1990).

Figure 1. Dendogram of cluster analysis results from phospholipid fatty acid profiles of rhizosphere and nonvegetated soils from the contaminated site. Comparisons of qualitative differences between the groups of microorganisms present in the different samples illustrated the primary clustering of nonvegetated soil samples with Lespedeza cuneata rhizosphere soil samples, and Solidago sp. rhizosphere soil with Firms taeda rhizosphere soil and Paspalum notatum rhizosphere soil samples. Secondary clustering occurred between Firms taeda soil samples and Faspalum notatum soil samples.

GIvcosides Isolated from Natural Products.—As is usual practice, only selected papers are referred to in this section. To add to the list of D-allopiyranosides isolated from natural sources the butenyl compound (63) has been obtained from the leaves of Cardiomanes reniforme ° The vinyl glycoside (64) occurs in the leaves of G. pneumonanthe, and the similar isomeric substances potassium lespedezate and isolespedezate (65) were isolated from Lespedeza cuneata and also synthesised. ...
