Tissue-specific metabolite profiling of Fallopia multiflora (Heshouwu) and Fallopia multiflora var. angulata by mass spectrometry imaging and laser microdissection combined with UPLC-Q/TOF-MS.

Maximizing seedling and root tuber production in Polygonum multiflorum for use in ethnomedicine

Identification and localization of morphological feature-specific metabolites in Reynoutria multiflora roots.

The structure of Polygonum multiflorum root,stem,leaf and root tuber and its anthraquinones distribution were studied to provide a reference to study the accumulation regulation of its anthraquinones.The results showed that the primary and secondary structure of the root and stem and the leaf structure is similar to dicotyledon.The root tuber is composed of periderm,secondary phloem,abnormal vascular,secondary xylem,and primary xylem.The abnormal vascular is the kind of amphicribral vascular bundle.Its anthraquinones is mainly distributed in root tubers and the anthraquinones content in its stem,root and leaf is little.

Study on Anatomy of Vegetative Organs of Polygonum multiflorum and Its Anthraquinones Distribution

In this paper,content changes of stilbene glucoside in Polygonum multiflorum Thunbare investigatedThe results indicate:the content of stilbene glucoside in the root tuber is the highest,then the old root and old stem,but it is very low in the young parts of vegetative organs and generative organIt is gradually increased in the root tuber and old stem with adding of growth yearsIt increased from June to October,reached the highest value in October,then drops graduallyIt is the highest in parts of the root tuber,the lowest in the parenchymaCongsidering content changes of stilbene glucoside,a rational gather time is in October,and old root and old stem should make full use
