Popis: | For the preliminary elimination from fig leaves of ballast substances of resinous nature and pigments such as chlorophyll and carotenoids, 2 kg of comminuted raw material was extracted three times with gasoline and then with dichloroethane. The material was steeped in the solvent for 8 h each time. The dichloroethane extracts were concentrated to dryness in vacuum, and the yield of technical furocoumarins totalled 0.58%, while the yield of purified soberan was 0.24% on the weight of the raw material. |
