High yield compounds as markers

Spinasterol (1) and four flavonoids (2-5) were isolated from Albizia myriophylla wood collected at Phu Yen province, Vietnam. The chemical structures of these compounds were elucidated by NMR spectroscopy as well as compared with data in the literature. The contents of some high yield isolated compounds (2-4) in the ethanol extract of A. myriophylla were quantified by high-performance liquid chromatography. These HPLC chromatograms could be used to reveal the presence of isolated compounds as markers of the sample.

Commiphora wightii (Arnott) Bhandari contains secondary metabolites, polysaccharides and phenolic compounds. The presence of secondary metabolites, reduce the yield and quality of the DNA. In the present study an alternative protocol for genomic DNA extraction from dry plant leaves was developed that is acquiescent to PCR-based genomic studies. Existing protocols were lengthy, costly or not appropriate for genomic DNA extraction from dry leaves. This modified CTAB (3%) and PVP (Polyvinylpyrrolidone) 1.5% protocol include the use of 0.5M NaCl, 0.
