Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Synthesis of betulinic acid was performed from the birch bark extract (Betula pendula). Betulonic acid was intermediate of the synthesis. Both acids were isolated with purity 95%. Genotoxicity and mutagenicity of obtained compounds were analyzed by Ames test and SOS chromotest, none of these

Ingia / Ingia

Microbial transformation of betulin (1), a lupane-type triterpene obtained from the bark extract of white birch (Betula platyphylla Sukatshev var. japonica), and its chemical oxidation product, betulonic acid (2), by the fungus Chaetomium longirostre yielded

Chemical profiles of birch and alder bark by ambient mass spectrometry.

Ingia / Ingia

Desorption atmospheric pressure photoionization (DAPPI) is an ambient mass spectrometry (MS) technique that allows the analysis of both polar and nonpolar compounds directly from the surfaces of various sample types. Here, DAPPI was used to study the chemical profiles in different parts of birch and
