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
Pine knots are a rich source of lignans, flavonoids and stilbenes. These bioactive compounds are widely known for their roles to combat human disorders but also to protect plants against pathogens. In order to gain knowledge inside their potential activities, a suitable isolation and purification of
OBJECTIVE
To study the chemical constituents of the pine needles from Pinus massoniana Lamb..
METHODS
Various chromatographic techniques were used for the separation and purification. The physicochemical properties and spectral data were used to elucidate the structures.
RESULTS
Three compounds were
The diet rich in fruits and vegetables reduces the risk of metabolic syndrome, including diabetes development by various mechanisms of action, mainly due to the presence of polyphenolic compounds. Extracts from different conifer species are known to be a rich source of various polyphenols. In the
Pine knot extract from Pinus pinaster byproducts was characterized by UHPLC-DAD-MS and NMR. Fourteen polyphenols divided into four classes were identified as follows: lignans (nortrachelogenin, pinoresinol, matairesinol, isolariciresinol, secoisolariciresinol), flavonoids (pinocembrin, pinobanksin,
