Cytotoxic isoprenylated flavans of Broussonetia kazinoki.
Two new prenylflavans [kazinols Q (1) and R (2)] and five known compounds [kazinols D (3), K (4), and H, 7,4'-dihydroxyflavan (5), and oleanolic acid] were isolated from the root bark of Broussonetia kazinoki. The cytotoxic activity of 1-5 was evaluated against several different cell lines.
متن کاملXerospiraea, A Generic Segregate of Spiraea (Rosaceae) from Mexico
The xeromorphic Mexican spiraeas (S. hartwegiana and S. northcrajii1) are shown by cladistic and phenetic analysis to be more closely allied to Petrophytum, Kelseya, and Luetkea than to the more mesophytic Spiraea. Within Spiraea the Mexican spiraeas appear more closely related to the Old World subgenus Metaspiraea. The xeromorphic Mexican spiraeas, as well as Petrophytum, Kelseya and Luetkea, ...
متن کاملA new phenolic glycoside from Spiraea prunifolia var. simpliciflora twigs.
The phytochemical investigation of the methanol extract from the twigs of Spiraea prunifolia var. simpliciflora (Rosaceae) using column chromatography led to the isolation of a new phenol glycoside, 1-O-(E)-caffeoyl-2-O-p-(E)-coumaroyl-β-D-glucopyranose (1), together with 16 known phenolic compounds (2-17). The structure of this new compound was elucidated by analysis of spectroscopic data incl...
متن کاملA revision of the Chinese species of Cyamophiliopsis (Hemiptera: Psylloidea: Psyllidae) associated with Spiraea (Rosaceae).
Cyamophiliopsis is a small genus restricted to the Palaearctic Region and associated with Spiraea spp. (Rosaceae). In the present work, following five species are recognized in China: C. pseudofasciata sp. nov., C. sarmatica, C. spinosa sp. nov., C. xinjiangana sp. nov. and C. zaisani. Cyamophiliopsis is diagnosed, redescribed in detail, and its phylogenetic relationships are discussed. All the...
متن کاملIsolation of 16 microsatellite markers for Spiraea alpina and S. mongolica (Rosaceae) of the Qinghai–Tibet Plateau1
UNLABELLED PREMISE OF THE STUDY A set of microsatellite markers were developed to characterize the level of genetic diversity and gene flow in two plant species endemic to the Qinghai-Tibet Plateau, Spiraea alpina and S. mongolica. • METHODS AND RESULTS Using the Fast Isolation by AFLP of Sequences COntaining repeats (FIASCO) method, 16 microsatellite loci showed polymorphisms in both spec...
