摘要：
Lamellar single crystals of V-amylose have been prepared from dilute solutions in the presence of various complexing agents (isopropanol, thymol, linalool, terpineol, alpha-naphthol and quinoline). They were characterized by means of electron microscopy imaging and electron crystallography. Crystals of the V-isopropanol-type were more frequently obtained even with complexing molecules with different sizes and chemical structures. alpha-naphthol and quinoline formed crystals involving 8-fold amylose helices. Flower-like "pseudo-spherocrystals" of lamellar units were observed when the crystallization was carried out at higher amylose concentration.
