Delphinidin-3-O-rutinoside

The fruits of Cornus alternifolia showed similar anthocyanin profile as those of Cornus controversa [Vareed et al., 2006], the relative amounts of anthocyanins in these fruits were found in the following order delphinidin-3-O-rutinoside > delphinidin-3-O-glucoside cyanidin-3-O-glucoside. The anthocyanin content in Cornus alternifolia fruits was several times higher than in other commonly consumed fiuits. 

Delphinidin-3-O-glueoside and delphinidin-3-O-rutinoside isolated from Comus kousa fruits were evaluated for their inhibitory activities on tumor cell proliferation, lipid peroxidation and cyelooxygenase enzymes (COX), showing potent effects [Vareed et al., 2006]. 

Quercetin, isorhamnetin, quercitrin, kaempferol 3-O-rutinoside, isorhamnetin 3-O-glucoside, and morin Betulinic acid, oleanolic add, and ursolic add Vanillic acid, caffeic add, p-coumaric add, ferulic acid, delphinidin, cyanidin, quercetin, kaempferol, isorhamnetin, procyanidin B2, and procyanidin B3... 

In recent years, various important biologieal activities, such as antioxidant, antimutagenic, anticancer, anti-inflammatory and antiobesity properties of anthocyanins have been reported. The methanol extraet of C. altemifolia and C. controversa inhibited lipid peroxidation by 56% and 53% respeetively, while delphinidin-3-O-glncoside and delphinidin-3-0-rutinoside isolated from these fiiiits presented a higher inhibition of 71% and 68% respeetively, at 5 time lower eoneentrations [Vareed et al., 2006]. 

The effects of pH under model conditions (0.6 to 5.5 for 24 hr) were covered by Nielsen et al. for four anthocyanins (3-O-glucoside, glycosylated cyanidin, rutinoside, and delphinidin rutinoside). After 24 hr, over 90% of the anthocyanins were intact up to pH 3.3, while instabihty greatly increased at pH greater than 4.5.
