An alkaloid, also belonging to the pyrrolizidine group, this base has been found
in Rindera baldshuanica Kusn. It forms colourless crystals from Me2CO and has
[α]20D + 24.62° (EtOH). Three non-phenolic hydroxyl groups are present and the
alkaloid forms well crystalline salts with mineral acids, e.g. the hydrochloride,
m.p. 152-3°C; hydrobromide, m.p. 123-4°C and the hydriodide, m.p. 118-
9°e. The structure may be deduced from the hydrolysis products which are
heliotridine and (+ )-trachelanthic acid.
Rinderine is a pyrrolizidine alkaloid which are a class of compounds used as defense mechanisms in several plant families. Rinderine may be used by other insects, sequestered from food in use for their own defense and may also be found in some medicinal herb preparations.
ChEBI: Rinderine is a member of pyrrolizines.
