Carotenoids from fruit of several Rosa species

This is an excerpt from the content

Fruits of plants of the genus Rosa L. are rich in carotenoids [1]. They provide raw material for producing the preparation Carotolin and fatty oil [2]. In continuation of studies of Rosa species growing in Nakhchivan AR [3,4], we studied the quantitative content and qualitative composition of carotenoids from four Rosa species, R. canina L., R. corymbifera Borkh., R. nisami Sosn., and R. teberdensis Chrshan. section canina Crep.

Fruit samples for analysis were collected when ripe from various sites in the mountainous part of the republic, R. canina (Karabagly, Kengerli Region); R. corymbifera (Chalkhangala, Kengerli Region); R. nisami (Bichenak, Shakhbuz Region); R. teberdensis (Nurgut, Ordubad Region). Carotenoids were isolated by the method of Novruzov et al. [5]. The quantitative content of carotenoids was determined colorimetrically [6] on KFK-2. The carotenoid composition was established by TLC [7]. Absorption maxima were measured on a Specord-40 spectrophotometer.
