Identification of campesterol from Chrysanthemum coronarium L. and its antiangiogenic activities.
Campesterol, a plant sterol in nature, is known to have cholesterol lowering and anticarcinogenic effects. Since angiogenesis is essential for cancer, it was surmised that an antiangiogenic effect may be involved in the anticancer action of this compound. This study investigated the effect of campesterol on basic fibroblast growth factor (bFGF)-induced angiogenesis in vitro in human umbilical v...
متن کاملCaffeoylquinic Acids from the Aerial Parts of Chrysanthemum coronarium L.
To elucidate the chemical compositions of the aerial parts of Chrysanthemum coronarium L., the ethanol extracts of Ch. coronarium L. were firstly isolated by the MCI-gel resin column. The caffeoylquinic acid-rich fractions were further purified by various chromatographic columns including silica gel, Sephadex LH-20, and semi-preparative HPLC to yield the compounds. The purified compounds were c...
متن کاملContents and Cooking Loss of Three Quinic Acid Derivatives from Garland (Chrysanthemum coronarium L.)
Three quinic acid derivatives, i.e., chlorogenic acid (CA), 3,5-dicaffeoylquinic acid (SP-1), and 3,5dicaffeoyl-4-succinylquinic acid (SP-2), determined in five garland (Chrysanthemum coronarium L.) cultivars were analyzed using HPLC. Young leaves contained greater amounts of these compounds than other parts, and mean dry weight content was 5.4 mg/g for CA, 22.9 mg/g for SP-1, and 20.8 mg/g for...
متن کاملIdentification of Chrysanthemum (Chrysanthemum morifolium) Self-Incompatibility
There has been a heated argument over self-incompatibilityof chrysanthemum (Chrysanthemum morifolium) among chrysanthemum breeders. In order to solve the argument, we investigated pistil receptivity, seed set, and compatible index of 24 chrysanthemum cultivars. It was found that the 24 cultivars averagely had 3.7-36.3 pollen grains germinating on stigmas at 24 hours after self-pollination throu...
متن کاملthe aesthetic dimension of howard barkers art: a frankfurtian approach to scenes from an execution and no end of blame
رابطه ی میانِ هنر و شرایطِ اجتماعیِ زایش آن همواره در طولِ تاریخ دغدغه ی ذهنی و دل مشغولیِ اساسیِ منتقدان و نیز هنرمندان بوده است. از آنجا که هنر در قفس آهنیِ زندگیِ اجتماعی محبوس است، گسترش وابستگیِ آن با نهاد ها و اصولِ اجتماعی پیرامون، صرفِ نظر از هم سو بودن و یا غیرِ هم سو بودنِ آن نهاد ها، امری اجتناب ناپذیر به نظر می رسد. با این وجود پدیدار گشتنِ چنین مباحثِ حائز اهمییتی در میان منتقدین، با ظهورِ مکتب ما...
