RESUMEN
The complete mitochondrial genome of Aucklandia lappa was sequenced for the first time. The mitochondrial genome length was 320,439 bp, with 45.05% GC contents. There were 67 genes annotated, including 31 known protein-coding genes, 25 tRNAs, and six rRNAs. The maximum likelihood method was used to establish the phylogenetic tree of 37 species. Results have shown that A. lappa and Arctium lappa were sister groups. It reveals the genetic relationship between different species and provides a theoretical basis for the establishment of a classification system.
RESUMEN
Aconitum kusnezoffii Rchb. is a medicinal plant in the Ranunculaceae family. In this study, we report the first complete mitochondrial genome of A. kusnezoffii. The total length of the mitochondrial genome of A. kusnezoffii is 440,720 bp and the GC content of 46.85%. The mitochondrial genome contained 37 protein-coding genes, 29 tRNAs, and three rRNAs. These data will provide the basis for the systematic evolutionary analysis of Ranunculaceae.
RESUMEN
The complete mitochondrial genome of an important medicinal plant Glycyrrhiza uralensis Fisch. is reported for the first time. The mitochondrial genome sequence of G. uralensis was 463,869 bp in length and had a GC content of 45.19%. The genome contained 40 protein-coding genes (PCGs), 30 transfer RNAs (tRNAs), and three ribosomal RNAs (rRNAs). The phylogenetic tree was built based on 25 plants, using the maximum-likelihood method. These data will provide certain help to determine the taxonomic status of G. uralensis.
RESUMEN
Eleven compounds were purified from the anti-inflammatory extract of Picris davurica by column chromatograph on HP20 macroporous resin, MCI, sephadex LH-20 and ODS.Their structures were determined by the spectra data of NMR and MS as isoestin 7-O-ß-D-glucopyranosyl-2'-O-α-L-arabinopyranoside(1), isoetin-7-O-ß-D-glucopyranosyl-2'-O-ß-D-xyloypyranoside(2), isoetin-7-O-ß-D-glucopyranosyl-2'-O-α-D-glucopy- ranoside(3), isoetin 5'-O-ß-D-glucopyranoside(4), isoetin-2'-O-ß-D-xyloypyranoside(5), isoetin-4'-O-ß-D-O-ß-D-glucopyranoside(6), isoetin-7-O-ß-D-glucopyranoside(7), isoestin-2'-O-α-L-arabinopyranoside(8), luteolin-7-O-ß-D-glucopyranosie(9), isoetin(10) and luteolin (11). All compounds were isolated from this plantfor the first time.Among them, compounds 1-8 were isolated from the genus Picris for the first time.
