Efficient Identification of (Ranunculaceae) Using DNA Barcodes and Micro-Morphological Characters.

(Ranunculaceae) comprises about 40 species, many of which have horticultural and/or medicinal importance. However, the recognition and identification of wild species is difficult due to the presence of complex morphological characters. DNA barcoding is a powerful molecular tool capable of rapidly and accurately distinguishing between species.

Isolation, Structural Elucidation, Optical Resolution, and Antineuroinflammatory Activity of Phenanthrene and 9,10-Dihydrophenanthrene Derivatives from .

A phytochemical investigation of the aqueous EtOH extract of tubers afforded 34 phenanthrene and 9,10-dihydrophenanthrene derivatives, including four new compounds, -. These compounds were identified using physicochemical analyses and various spectroscopic methods. Twelve of these compounds were resolved into their enantiomers, and the absolute configurations were determined by comparison of experimental and calculated ECD spectra.

Floral morphology and morphogenesis in Camptotheca (Nyssaceae), and its systematic significance.

Background And Aims: Camptotheca is endemic to China and there are limited data about the breeding system and morphogenesis of the flowers. Camptotheca is thought to be related to Nyssa and Davidia in Nyssaceae, which has sometimes been included in Cornaceae. However, molecular phylogenetic studies confirmed the inclusion of Camptotheca in Nyssaceae and its exclusion from Cornaceae.

The complete chloroplast genome of the marsh plant- (Asteraceae).

is an important marsh plant. The complete chloroplast genome sequence of . was obtained using next generation sequencing.

Mitochondrial genome of the African lion Panthera leo leo.

In this study, the complete mitochondrial genome sequence of the African lion P. leo leo was reported. The total length of the mitogenome was 17,054 bp.

Phenolic glycosides from Curculigo orchioides Gaertn.

Five new chlorophenolic glucosides, curculigine E (1), curculigine F (2), curculigine G (3), curculigine H (5), curculigine I (6) and one new phenolic glycoside, orcinoside H (4), together with eight known phenolic glycosides (7-14) were isolated from the Curculigo orchioides Gaertn. Their structures were established by spectroscopic techniques (IR, UV, MS, 1D and 2D NMR). The isolated phenolic glycosides were evaluated for antiosteoporotic activity against MC3T3-E1 cell line using MTT assays.

Two new polyacetylenic compounds from Atractylodes chinensis (DC.) Koidz.

Two new polyacetylenic compounds, (6E,12Z)-tetradecadiene-8,10-diyne-1,3-diol (1) and (6Z,12Z)-tetradecadiene-8,10-diyne-1,3-diol (2), were isolated from Atractylodes chinensis (DC.) Koidz. Their structures were established by analysis of spectroscopic data.

DFL, a FLORICAULA/LEAFY homologue gene from Dendranthema lavandulifolium is expressed both in the vegetative and reproductive tissues.

FLO/LFY homologue genes were initially characterized as floral meristem identity genes and play a key role in flower development among diverse species. The inflorescence organization of chrysanthemum differs from typical dicotyledons such as Arabidopsis and Antirrhinum as clear sepals are absent, and instead, a pappus, a rudimentary sepal, is formed. To understand the mechanism of reproduction of chrysanthemum at the molecular level, DFL, a FLORICAULA/LEAFY homologous gene, was cloned from Dendranthema lavandulifolium, which is one of the original species of chrysanthemum.
