ABSTRACT
To understand the distribution and accumulation rules of polydatin, resveratrol, anthraglycoside B, emodin and physicion in different tissue structure of rhizome and root of Polygonum cospidatum, the content of 5 active compounds were analyzed simultaneously by HPLC, based on plant anatomy and histochemistry. The rhizome and root consist of different tissues, with an increased diameter, the proportions of the secondary xylem and phloem have increased. Resveratrol and polydatin mainly distributed in the pith, the secondary phloem and periderm of rhizome, and the secondary phloem and periderm of the root, while emodin and anthraglycoside B concentrated in the secondary structure and pith of rhizome mostly. In different thickness of the measured samples, the total contents of 5 compounds were correspondingly higher in thinner rhizome and root than those in the coarse ones.
