Ripe fruit of Pyracantha (Cotoneaster) angustifolia Schneid. constitutes the best practical source for the isolation of pro-γ-carotene, C40H56, and a good source for prolycopene, C40H56, both of which possess partially cis configurations. The yields were 27.7 mg. of crystallized pro-γ-carotene and 28.4 mg. of prolycopene from 1 kilo of air-dried berries. A close stereoisomer of prolycopene was also isolated (7.3 mg.) and a monohydroxy pro-γ-carotene observed in solution.
