[A histochemical study on baicalin].
Baicalin in the root of Scutellaria baicalensis was analysed histochemically by means of TLC and HPLC. It was determined that the content of baicalin in phloem was 11.08%, in xylem 7.86%, in phellem 2.19% and in centric decayed part 0.815%. Thus the quality of root of Scutellaria baicalensis is believed to consist in thin phellem, high ratio of phloem to xylem and absence of centric decayed part.
