TL;DR: Phytochemical investigation of the roots of Cratoxylum formosum spp.
Abstract: Phytochemical investigation of the roots of Cratoxylum formosum spp. pruniflolnnm led to the isolation and identification of a new xanthone, namely cratopruniforone (1), together with 13 known compounds (2-14). Some of these more abundant compounds were evaluated for their antibacterial activities.

TL;DR: In this article, three xanthones and their glycosides have been isolated from Halenia corniculata and identified as 1-hydroxy-2, 3, 5, 7, 7-tetramethoxyxanthone (1), 1-H2, 2,3, 4,5,7, 5.5-trimethoxy-1-0-prime-verosyloxy xanthone glycoside.
Abstract: Three xanthones and their glycosides have been isolated from Halenia corniculata. They were identified as 1-hydroxy-2, 3,5,7-tetramethoxyxanthone (1), 1-hydroxy-2,3,4,5-tetramethoxyxanthone (2), 1-hydroxy-2,3,5-trimethoxyxanthone (3), 2,3,5,7-tetramethoxy-1-0-primeverosyloxyxanthone (4), 2,3,4,5-tetramethoxy-1-0-primeverosyloxyxanthone (5) and 2,3,5-trimethoxy-1-0-primeverosyloxyxanthone (6). Of these, (1) and (4) are new xanthone and xanthone glycoside, while (2), (3), (5) and (6) were isolated for the first time.

TL;DR: The crystal structure of isogentisin, C14H10O5, a natural product isolated from Gentiana lutea, has been determined as mentioned in this paper, and the phenolic ring system is essentially planar and the displacement of the methoxy substituent from the mean molecular plane is very small.
Abstract: The crystal structure of isogentisin, C14H10O5, a natural product isolated from Gentiana lutea, has been determined The phenolic ring system is essentially planar and the displacement of the methoxy substituent from the mean molecular plane is very small The structure is stabilized by a one-dimensional chain of intermolecular hydrogen bonds
