1.Research progress of relationship between each component of metabolic syndrome and hypertension
Chinese Journal of cardiovascular Rehabilitation Medicine 2015;24(1):110-113
Metabolic syndrome (MS)is a syndrome of multiple metabolic abnormality aggregation,including over-weight,hypertension,glucose and lipid metabolic abnormality and insulin resistance etc.Some researches demon-strated that over 80% EH patients may be complicated with MS,those patients with EH+MS possess higher risk for cardio-and cerebrovascular diseases than pure EH patients.This article made an overview on research about rela-tionship between EH and MS in recent years.

OBJECTIVETo establish a quantitative method for determination of gallic acid, original catechins, catechins, chlorogenic acid, caffeic acid, syringic acid in Lycium ruthenicum.
METHODThe sample was separated on an ODS column (4. 6 mm x 250 mm, 5 pnm), eluted with methanol and water containing 0. 1% acid with detected wavelength at 280 nm, and flow rate at 1. 0 mL x min(-1).
RESULTThe linearity of six components were good (r = 0.9999). The average recoveries (n=5) of the six constituents were 97. 70% (RSD 2.3%), 99.64% (RSD 1.8%), 100.7% (RSD 2.1%), 99.98% (RSD 2.6%), 99.60% (RSD 2.2%), 99.04% (RSD 2.4%), respectively.
CONCLUSIONThe method is rapid and precise. It can be used for quality control of Lycium ruthenicum juice.
