Two new compounds from the roots of Rhodiola crenulata.
Summary of "Two new compounds from the roots of Rhodiola crenulata."
Two new compounds, named (3R,5R,8R)-3-O-[Î±-l-arabinopyranosyl (1Â â†’Â 6)-Î²-d-glucopyranosyl]-5-hydroxymegastigma-6,7-dien-9-one (1) and (1R)-1-O-(Î²-d-glucopyranosyl)-phenylethylene glycol (2), were isolated from the extract of Rhodiola crenulata. Their structures were determined on the basis of various spectroscopic methods, including IR, HR-ESI-MS, 1D and 2D NMR, and chemical evidences. The cytotoxicity of these two compounds was evaluated by using MTT method.

Medical and Biotech [MESH] Definitions
Root-like underground horizontal stem of plants that produces shoots above and roots below. Distinguished from true roots which don't have buds and nodes. Similar to true roots in being underground and thickened by storage deposits.
Spinal Nerve Roots
The paired bundles of nerve fibers entering and leaving the spinal cord at each segment. The dorsal and ventral nerve roots join to form the mixed segmental spinal nerves. The dorsal roots are generally afferent, formed by the central projections of the spinal (dorsal root) ganglia sensory cells, and the ventral roots efferent, comprising the axons of spinal motor and autonomic preganglionic neurons. There are, however, some exceptions to this afferent/efferent rule.
Symbiotic combination (dual organism) of the MYCELIUM of FUNGI with the roots of plants (PLANT ROOTS). The roots of almost all higher plants exhibit this mutually beneficial relationship, whereby the fungus supplies water and mineral salts to the plant, and the plant supplies CARBOHYDRATES to the fungus. There are two major types of mycorrhizae: ectomycorrhizae and endomycorrhizae.
A plant genus of the family CRASSULACEAE. Some species in this genus are called stonecrop which is also a common name for RHODIOLA.
A plant genus in the family ROSACEAE and order Rosales. This should not be confused with the genus RHODIOLA which is sometimes called roseroot.
