Polygonatum sibiricum

An indolizidine alkaloid isolated from the rhizomes of Polygonatum sibiricum (Liliaceae) also has some unusual features 311). The unnamed alkaloid, for which the structure 326 has been proposed on the basis of good spectroscopic data (IR, UV, MS H, C and HETCOR NMR), is the first 5,6,7,8-tetrahydroindolizine (cyclohexa[a]pyrrole) to have been found as a natural product. In addition, the ethoxymethyl substituent is unique, at least among the natural indolizidines. It should also be pointed out that simple indolizidine alkaloids have never before been isolated from liliaceous species. Although the structure 326 appears to be reasonable in the light of the spectroscopic evidence, judgement should perhaps be reserved until it can be confirmed independently. 

Rhizoma Polygonati, the dried rhizome of Polygonatum sibiricum Red, with sweet and neutral properties, enters the spleen, lung and kidney meridians . The functions are to nourish the Yin and moisten the lungs, to tonify the spleen and promote vital energy [86].
