Squalene Extraction: Biological Sources and Extraction Methods

Sources of Success for Information Extraction Methods

In this paper, we examine an important recent rule-based information extraction (IE) technique named Boosted Wrapper Induction (BWI), by conducting experiments on a wider variety of tasks than previously studied, including tasks using several collections of natural text documents. We provide a systematic analysis of how each algorithmic component of BWI, in particular boosting, contributes to i...

Information Extraction and Integration from Heterogeneous Biological Data Sources

There are huge and growing amounts of biological data that reside in different online repositories. Most of these Web-based sources only focus on some specific areas or only allow limited types of user queries. To obtain needed information, biologists usually have to traverse different Web sources and combine their data manually. In this research, we propose a system that can help users to over...

Biofuel: Sources, Extraction and Determination

Extraction and purification of squalene from amaranthus grain.

Grain amaranth has been suggested as an alternative to marine animals as a natural source of squalene. Oil contents, squalene contents, and fatty acid profiles were determined in 11 genotypes of four grain amaranth species. Although the oil contents of grain amaranth were low (from 5.1% in Amaranthus tricolor to 7.7% in Amaranthus cruentus) as compared to other oil-containing grains, high conce...

Methods for Obtaining and Determination of Squalene from Natural Sources

Squalene is a natural dehydrotriterpenic hydrocarbon (C30H50) with six double bonds, known as an intermediate in the biosynthesis of phytosterol or cholesterol in plants or animals. We have briefly reviewed the natural sources for squalene and focused on the main methods and techniques to obtain and to determine it. Some of its applications in different fields of human activity are also mentioned.
