- | Ficus carica is a dioecious species pollinated by a specific wasp, Blastophaga psenes L. Male trees produce only figs with pollen and fig wasps (pollen carriers), while female figs produce only seeds. Pollinators are able to discriminate between receptive and non-receptive figs based alone on volatiles. Pentane extracts of non-receptive male and female figs contained mainly sesquiterpenes (like caryophyllene and germacrene D) and benzyl alcohol. Principle compounds found in extracts of receptive male and female figs were linalool, linalool | + | Ficus carica is a dioecious species pollinated by a specific wasp, Blastophaga psenes L.

Figs which are intended for drying are harvested when fully ripe, when the water content of the fruit on the tree has already dropped (by 30-50%). Water content of ripe figs is lowered on drying to 33-18%, sugar content rises to 60%. \\ | Figs which are intended for drying are harvested when fully ripe, when the water content of the fruit on the tree has already dropped (by 30-50%).

"Based on sensitization reactions at 5% and strong phototoxic reactions, the Panel concluded that the material should be banned. A RIFM Advisory Letter (RIFM, 1980) was issued to all members stating the potential for induction of skin and phototoxic reactions. As a result, an IFRA Guideline (now renamed a Standard) was issued in October, 1980 (IFRA, 1980), which stated, ‘‘Fig Leaf Absolute should not be used as a fragrance ingredient based on test results of RIFM showing sensitizing and extreme phototoxic potential for this material.’’ A RIFM | "Based on sensitization reactions at 5% and strong phototoxic reactions, the Panel concluded that the material should be banned.
