TL;DR: In this article, the 13C nuclear magnetic resonance chemical shifts of aryl carbons in these C-glucosylxanthones (2-5) were assigned.
Abstract: Four C-glucosylxanthones [Mangiferin (3), isomangiferin (2), 4 and 5] and three C-glucosylflavones [swertisin (6), isoswertisin (7) and isoswertiajaponin (8)] were isolated from the fresh leaves of Iris florentina L. (Iridaceae). The structures of 4 and 5 were shown to be 7-O-methylmangiferin and 7-O-methylisomangiferin, respectively, by chemical and spectroscopic methods. In addition, the 13C nuclear magnetic resonance chemical shifts of aryl carbons in these C-glucosylxanthones (2-5) were assigned. On the basis of the co-occurrence of several types of xanthone and flavone C-glucosides, the biosynthetic relationship between both C-glucosides is briefly discussed.

TL;DR: In this paper, a new isoflavone glycoside, irifloside (III), C23H22O12·H2O, mp 177-178°, has been isolated from the rhizoma of Iris florentina L. (Iridaceae) together with iriflophenone (II), irisolone (IV), irisflorentin (I), iristectorigenin B (V), irigenin (VI), iridin (VII), and its aglycone, C17H12O
Abstract: Irifloside (III), C23H22O12·H2O, mp 177-178°, a new isoflavone glycoside, has been isolated from the rhizoma of Iris florentina L. (Iridaceae) together with iriflophenone (II), irisolone (IV), irisflorentin (I), iristectorigenin B (V), irigenin (VI) and iridin (VII). The structure of irifloside (III) has been determined as 5, 4'-dihydroxy-3'-methoxy-6, 7-methylenedioxyisoflavone-4'-O-β-D-glucoside by chemical degradation and spectral means, and its aglycone, C17H12O7, mp 221-223°, was named iriflogenin (VIII). The structure of iriflophenone (II), C13H10O5, mp 207-208°, has been determined as 2, 4, 6, 4'-tetrahydroxybenzophenone by spectral means.

TL;DR: In this article, a promising future for the cultivation of irises for rhizomes, various extracts but most importantly for high quality orris butter is discussed. And the authors suggest that Romania is situated in a transitional continental climate with suitable conditions for hardy iris species and thus with good prospects for successful cultivation of Iris germanica, Iris florentina and Iris pallida in conditions of economic efficiency.
Abstract: Rhizomes from various Iris species have been used in traditional medicine to treat a variety of ailments since ancient times and many constituents isolated from different Iris species demonstrated potent biological activities in recent studies. All research findings besides the increasing demand for natural ingredients in cosmetics and market demand from industries like alcoholic beverages, cuisine and perfumery indicate a promising future for cultivation of irises for rhizomes, various extracts but most importantly for high quality orris butter. Romania is situated in a transitional continental climate with suitable conditions for hardy iris species and thus with good prospects for successful cultivation of Iris germanica, Iris florentina and Iris pallida in conditions of economic efficiency.

TL;DR: Irisxanthone (IV), C20H20O11·H2O, decomposing over 208° without melting, has been isolated from the rhizoma of Iris florentina L. as discussed by the authors along with mangiferin.
Abstract: Irisxanthone (IV), C20H20O11·H2O, decomposing over 208° without melting, a new C-glycosylxanthone, has been isolated from the rhizoma of Iris florentina L. (Iridaceae) along with mangiferin. The structure of irisxanthone (IV) has been determined as 2-C-β-D-glucopyranosyl-5-methoxy-1, 3, 6-trihydroxyxanthone by chemical and spectral studies.

TL;DR: Almost all common classes of flavonoid are present, while the rarer biflavonoids characterise Isophysis and Patersonia and the anthocyanins in flowers are generally distinctive at the generic level.
Abstract: Just as the family Iridaceae is abundant in its morphological and anatomical diversity, so is it rich in its secondary metabolites. Many varied phytochemicals have been described from the family. Isoflavones, first recorded in Iris florentina, have recently been detected in Iris pseudopumila. Almost all common classes of flavonoid are present, while the rarer biflavonoids characterise Isophysis and Patersonia. The anthocyanins in flowers are generally distinctive at the generic level. Quinonoid and xanthone pigments have systematically interesting distribution patterns. Distinctive chemicals in Iris rhizome oils and in Crocus styles are useful economically. Yet other phytochemicals such as nonprotein amino acids and special storage carbohydrates have restricted distribution patterns.
