The complete chloroplast genome of Paeonia rockii (Paeoniaceae), an endangered endemic species to China

Conservation Genetics Resources, 2017
Paeonia rockii (Paeoniaceae) is an endangered endemic species to China and it is the most important ancestral species of the cultivated tree peonies. Here, the complete chloroplast (cp) genome of P. rockii was obtained by using Illumina pair-end sequencing. The complete cp genome of P. rockii was 152,821 bp, consisting of a pair of inverted repeat (IR)

Triterpenoid Constituents from the Roots of Paeonia rockii ssp. rockii

Journal of Natural Products, 2011
An investigation of a chloroform-soluble extract from the roots of Paeonia rockii ssp. rockii yielded three new noroleanane triterpenoids (1-3) together with 19 known compounds. Their structures were established by analysis of the spectroscopic data.

Transcriptome and miRNA sequencing analyses reveal the regulatory mechanism of α-linolenic acid biosynthesis in Paeonia rockii

Food Research International, 2022
Paeonia rockii is a promising woody oil crop because its seeds are rich in polyunsaturated fatty acids especially α-linolenic acid (ALA). ALA is an essential fatty acid that the human body cannot synthesize and is the direct synthetic precursor of eicosapentaenoic and docosahexaenoic acids, which play crucial roles in the development of the blood ...

Screening of a polar extract of Paeonia rockii: Composition and antioxidant and antifungal activities

Journal of Ethnopharmacology, 2011
The genus Paeonia (Paeoniaceae), is one of the most important source of crude drugs in traditional Chinese medicine and investigation on many species is large. Up to now studies on Paeonia rockii, one of the eight species recognized in the section Moutan, are very limited.This research aimed to investigate the composition of Paeonia rockii roots and to

Comprehensive metabolite profile of multi-bioactive extract from tree peony (Paeonia ostii and Paeonia rockii) fruits based on MS/MS molecular networking

Food Research International, 2021
Tree peony seed, traditionally used for edible oil production, is rich in α-linolenic acid. However, little attention is given to the fruit by-products during seed oil production. The present work aimed to comprehensively investigate the phytochemical constituents and multiple biological activities of different parts of tree peony fruits harvested from

Association mapping for floral traits in cultivated Paeonia rockii based on SSR markers

Molecular Genetics and Genomics, 2016
Tree peony (Paeonia Sect. Moutan) is an economically important ornamental plant, but little is known about the genetic architecture of important ornamental traits. To effectively improve ornamental value, we require a better understanding of genetic architecture in the complex traits of the tree peony.

Two New Resveratrol Trimers with Antibacterial Activities from Seed Cake of Paeonia rockii

Chemistry of Natural Compounds, 2017
Bioactivity-guided fractionation of the EtOAc-soluble fraction of the total ethanolic extract resulted in the isolation and identification of two new resveratrol trimers, rockiol A (1) and rockiol B (2). The relative configurations of these compounds were elucidated mainly by comprehensive 1D and 2D NMR experiments. The two isolated compounds exhibited

Cloning, Characterization, and Expression Analysis of a Gene Encoding a Putative Lysophosphatidic Acid Acyltransferase from Seeds of Paeonia rockii

Applied Biochemistry and Biotechnology, 2016
Tree peony (Paeonia section Moutan DC.) is an excellent woody oil crop, and the cloning and functional analysis of genes related to fatty acid (FA) metabolism from this organism has not been reported. Lysophosphatidic acid acyltransferase (LPAAT), which converts lysophosphatidic acid (LPA) to phosphatidic acid (PA), catalyzes the addition of fatty acyl
