Root of Glehnia littoralis (Umbelliferae), cultivated in Tottori Prefecture, was dried by various drying methods and thus prepared Glehnia roots were assayed for their amounts of six furanocoumarins, three sugars (fructose, glucose and sucrose) and dilute ethanol-soluble extract. The ratios (PXB/G) of the total amount of the stress compounds, psoralen, xanthotoxin and bergapten, to the amount of the main component, 5-geranyloxypsoralen (bergamottin), were compared. Increases of the amounts of sugars, dilute ethanol-soluble extract and the stress compounds and of the PXB/G values were observed during storage and drying, and apparently, there was a close correlation between the amounts of sugars and those of dilute ethanol-soluble extract. Differences of storage conditions of washed raw roots before hot-air drying affected the PXB/G values, the sugar contents and dilute ethanol-soluble extracts.
