Isolation, X-ray crystal structure of the new diterpene and identification of others lignans and flavonoids from the fresh needles of .

Three new compounds, namely massonside C (), massonianoside F (, and 3, 8-dimethyl- herbacetin-7-O-β-D-glucopyranoside (), together with five known compounds (-), were isolated from the fresh needles of . Their structures were established by 1D, 2D NMR, HRMS and comparison with the literature data. The absolute configuration of was confirmed by a combination of X-ray single crystal analysis.

Isolariciresinol-9'-O-α-L-arabinofuranoside protects against hydrogen peroxide‑induced apoptosis of human umbilical vein endothelial cells via a PI3K/Akt/Bad‑dependent pathway.

Isolariciresinol-9'-O-α-L-arabinofuranoside (MWS‑19) isolated from Pinus massoniana Lamb. Fresh pine needles is the major ingredient of the Songling Xuemaikang capsule therapy used for hypertension. The present study aimed to investigate the effects and underlying mechanisms of MWS‑19 on hydrogen peroxide (H2O2)‑induced apoptosis in human umbilical vein endothelial cells (HUVECs).

Two new sesquiterpene glycosides isolated from the fresh needles of Pinus massoniana Lamb.

Two new sesquiterpene glycosides, namely massonside A (1) and massonside B (2), were isolated from the n-Bu extract of the fresh needles of Pinus massoniana Lamb. Their structures were established by 1D, 2D nuclear magnetic resonance and high-resolution mass spectrometry. Their biological activities were profiled by the anti-HBV and anti-HCV assays.

[Relationship between selection of Pinus massoniana families and Folium Pini].

Based on variation of Pinus massoniana families, heritablility and correlation analysis, the contents of shikimic acid and procyanidine (heritability 0.90, 0.70), dry weight of single branch (heritability 0.

[Application of DTOPSIS method in quality control of commercial medicinal materials of Rheum palmatum].

Objective: To study the factors that affect the quality of Rhei Radix et Rhizoma, including those from different regions, of different specifications and different growth patterns.

Methods: Detect the contents of extract, total ash, acid-insoluble ash and active ingredients of Rhei Radix et Rhizoma from 18 different sources. The results were compared by SPSS software and DTOPSIS.
