how can i get posts from custom post type particular taxonomy category

If you read http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters in detail it outlines everything you need. Take a look at the following code sample taken from the codex. It should help you 🙂

$args = array(
    'post_type' => 'Article', /* This is where you should put your Post Type */
    'tax_query' => array(
        array(
            'taxonomy' => 'people',
            'field' => 'slug',
            'terms' => 'bob'
        )
    )
);
$query = new WP_Query( $args );
