Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain.

ABSTRACT Fucoxanthin a natural carotenoid derived from algae exhibits novel anticancer

25

potential. However, fucoxanthin with high purity was hard to prepare and the

26

anticancer mechanism remains elusive. In the present study, fucoxanthin with high

27

purity was prepared and purified from marine micralgae Nitzschia sp. by silica gel

28

column chromatography (SGCC), and the underlying mechanism against human

29

giloma cells was evaluated. The results showed that fucoxanthin time- and

30

dose-dependently inhibited U251 human glioma cells growth by induction of

apoptosis (64.4±4.8, P
