“…The EI-mass spectrum of compound 4 showed [M+1] + peak at m/z 131 consistent with the molecular formula C 6 H 10 O 3 , which was, confirmed with 13 1H, m). Furthermore, the 13 C-NMR spectra showed signal for a methyl group at  C 20.8 (q),two signals for methylene carbons at  C 38.1(t) and 35.6 (t), two signals for oxygenated methine carbons at  C 72.8 (d) and 67.4 (d) and a lactone carbonyl carbon at  C 169.0 (s).…”

‫منها‬ .A hydrocarbon alcohol, nonacosanol (1), -amyrin (2) and -sitosterol (3) were isolated from the n-hexane fraction of the methanolic extract of Ixora finlaysoniana. From the chloroform fraction, four compounds were isolated; 3-hydroxyhexan-5-olide (4), protocatechuic acid (5), gallic acid (6) and -sitostreol glucoside (7). In addition to three compounds were isolated form the ethyl acetate fraction; parasorboside (8), D-1-O-methylmyo-inostiol (9) and galactitol (10). The structures of the isolated compounds were elucidated on the basis of physical, chemical and spectroscopic evidence.

“…Flavonoids are the major active ingredient. Kaempferol (7) and luteolin (6) isolated from this plant showed more significant inhibition than aspirin (IC 50 13.58 lg/ml) with IC 50 values of 3.55 and 2.56 lg/ml, respectively. In a simple structure-activity relationship study, flavonone or flavononol was more favorable than flavane, and the flavonoids that have rhamnosyl functionality remarkably reduced the inhibitory activity of collagen-induced aggregation [9].…”

Ixora is a genus of ca. 400 species in the family Rubiaceae. Since the 1940s, eighty-one compounds including phenolics, peptides, terpenoids, and sterols have been isolated from six species of the genus Ixora. Pharmacological studies have shown that these compounds and extracts from the Ixora genus have extensive activities, such as antitumor, chemoprotective, and antioxidant activities. In this review, we summarize the phytochemical progress and list the compounds isolated from the genus Ixora. The biological activities of this genus are also covered.
