The present study was carried out to study the effect of antioxidants on oxidised LDL + VLDL and found that vitamin E, eugenol and tincture of crataegus (antioxidants) inhibited oxidation of (LDL + VLDL) similar to standard antioxidant (butylated hydroxy toluene). Vitamin C acted as an antioxidant at lower concentration, and prooxidant at higher concentration.

An agamic complex of 20- and 10-stamen, black-fruited hawthorns (Crataegus subg. Sanguineae, sect. Douglasianae) occurs in western North America, with a 10-stamen taxon disjunct the upper Great Lakes basin. Here, we recircumscribe 20-stamen taxa at core this (C. ser. Douglasianae). This is needed order to distinguish between presumptively ancestral diploid its allo- autopolyploid derivatives, a...

Chinese hawthorn (Crataegus pinnatifida Bge.) fruits are rich in polyphenols (e.g., epicatechin, procyanidin B2, procyanidin B5, procyanidin C1, hyperoside, isoquercitrin and chlorogenic acid)--active compounds that exert beneficial effects. This review summarizes all information available on polyphenolic content and methods for their quantification in Chinese hawthorn berries and the relations...

[1] We use Interferometric Synthetic Aperture Radar (InSAR) to search for surface deformation in the southern Andes (40 S–46 S and 49 S–53 S) associated with magmatic processes. Although the available data are not optimal, we can constrain the amount of volcanic deformation at about 27 Holocene volcanoes between the years 1993–1999. We detect inflation of Cerro Hudson volcano following its 1991...

A New pregnane type Alkaloid named Sracosalgminol [(20S)-20-(dimethylamino)-3β-methoxy-16β-hydroxyl-pregn-5-ene] was isolated from sarcococca saligna and its structure was established on the basis of spectroscopic techniques includingH,13C-NMR and inverse 2D-NMR techniques (DEPT,HMQC and HMBC) UV,MS etc.

The occurrence of triterpene pentacyclic acids in plants is extensive, but little is known about their availability in commercial extracts. A simple GC-MS method for the simultaneous determination of betulinic, corosolic, maslinic, oleanolic and ursolic acids was developed and applied to 38 different commercial plant extracts sold as ingredients for dietary supplements. A suitable protocol was ...
