I. l~r i s t a v i UDC 547.972 Continuing an investigation of P a s s i f l o r a incaruata L., cultivated in Tbilisi, we have studied the substances of flavonoid nature of the leaves and flowers of this plant collected in August, 1971, in the flowering phenophase.

We have previously reported a study of the components of P. incarnata L. [1-3]. The present paper gives the results of an investigation of the free sugars of this plant. The comminuted fresh roots (i kg) were extracted with boiling methanol (4 × 4 liters). The extract was concentrated to 0.5 liter, 0.5 liter of acetone was added, and the mixture was filtered and was left at room temperature. Crystals separated out which, after four days, were filtered off and dried. This gave 49.4 g of product (4.94% of the weight of the dry roots). By paper chromatography (PC) [butan-l-ol-acetic acid-water (4:1:5) system; chromogenic agen t aniline phthalate] it was found that it consisted of the combined free sugars, comprising four substances.
