What is Das Carotinoidspektrum der Hagebutten von Rosa pomifera : Nachweis von (5 Z )‐Neurosporin; Synthese von (3 R , 15 Z )‐Rubixanthin about?

**Carotenoids from Hips of __Rosa pomifera__: Discovery of (5__Z__)‐Neurosporene; Synthesis of (3__R__, 15__Z__)‐Rubixanthin** Extensive chromatographic separations of the mixture of carotenoids from ripe hips of __R. pomifera__ have led to the identification of 43 individual compounds, namely __(Scheme 2)__: (15 __Z__)‐phytoene **(1)**, (15 __Z__)‐phytofluene **(2)**, all‐(__E__)‐phytofluene **(2a)**, ξ‐carotene **(3)**, two mono‐(__Z__)‐ξ‐carotenes (**3a** and **3b**), (6 __R__)‐ε, ψ‐carotene **(4)**, a mono‐(__Z__)‐ε, ψ‐carotene **(4a)**, β, ψ‐carotene **(5)**, a mono‐(__Z__)‐β, ψ‐carotene **(5a)**, neurosporene **(6)**, (5 __Z__)‐neurosporene **(6a)**, a mono‐(__Z__)‐neurosporene **(6b)**, lycopene **(7)**, five (__Z__)‐lycopenes **(7a–7e)**, β, β‐carotene **(8)**, two mono‐(__Z__)‐β, β‐carotenes (probably (9 __Z__)‐β, β‐carotene **(8a)** and (13 __Z__)‐β, β‐carotene **(8b)**), β‐cryptoxanthin **(9)**, three (__Z__)‐β‐cryptoxanthins **(9a–9c)**, rubixanthin **(10)**, (5′ __Z__)‐rubixanthin (=gazaniaxanthin; **10a**), (9′ __Z__)‐rubixanthin **(10b)**, (13′ __Z__)‐ and (13 __Z__)‐rubixanthin **(10c** and **10d**, resp.), (5′ __Z__, 13′ __Z__)‐ or (5′ __Z__, 13 __Z__)‐rubixanthin
