Subcellular distribution and chemical forms of cadmium in Morus alba L.

Morus alba L. (mulberry) is a perennial woody tree and a species with great potential for Cd phyremediation owing to its large biomass and extensive root system. The mechanisms involved in Cd detoxification were investigated by analyzing the subcellular distribution and chemical forms of Cd in mulberry in the present study.

[Comparative and correlational studies on contents of stilbenes in different portions of mulberry].

Objective: To compare the contents of stilbenes in different parts and axial root bark of mulberry, and study their correlation.

Method: The contents of 3 major stilbenes, mulberroside A, oxyresveratrol, and resveratrol in different parts of mulberry were determined by HPLC. The correlation and regression analysis between the contents of stilbenes in the different parts and axial root bark was carried out.

Variations in the levels of mulberroside A, oxyresveratrol, and resveratrol in mulberries in different seasons and during growth.

This study aimed to investigate the composition of three major stilbenes (mulberroside A, oxyresveratrol, and resveratrol) in different portions of mulberries collected in different seasons and their change molds during growth by high-performance liquid chromatography. Mulberroside A levels were the highest in the bark and roots of Morus atropurpurea Roxb, Morus alba Linn, and Morus latifolia Poir. Oxyresveratrol levels were the highest in roots and stem.
