Chemistry

Flavonoids (0.5-1.5%) and the oligomeric procyanidins (OPC's, 2.2-3.3%) are regarded as active constituents of hawthorn. The primary flavonoid in the leaves is vitexin-2"-O-rhamnoside or occasionally acetylvitexin-2"-O-rhamnoside;

in the flowers it is hyperoside. The flavonoids are composed of flavanol aglycones and flavanol O-glycosides (quercetin, kaempferol, hyperoside, isoquercitroside, spirein, rutin among others),

flavone-O-glycosides (quercetin, kaempferol, hyperoside, isoquercitroside, spirein, rutin among others) flavone-O-glycosides (luteolin-7-O-glucoside), flavone-C-glycosides (vitexin, isovitexin, orientin and isoorientin),

flavone-C-O-glycosides (vitexin-2"-O-rhamnoside and acetylvitexin-2"-O-rhamnoside among others) and flavone-di-C-glycosides. The procyanidin fraction is composed of 2 to 8 (+)-catechin and (-)-epicatechin units.

The dimeric procyanidin B-2 and the trimeric procyanidin C-1 are the main constituents. Some procyanidin tetramers are present.Aromatic carbonic acids, mainly chlorogenic acid and caffeic acid, pentacyclic triterpenoid acids such as oleanolic acid,

ursolic acid, crataegolic acid as well as nitrogen-containing compounds such as choline and acetychloine were cited in older literature as components of the drug.

Indications

Hawthorn extract is an herbal preventive and therapeutic agent for cardiac insufficiency. It improves the efficiency of the heart by increasing blood supply to the heart muscle so the heart is able to pump more blood to the body.

Hawthorn lowers the resistance to blood flow in peripheral vessels. Hawthorn can be used alone or in conjunction with other conventional or botanical drugs for a wide variety of mild cardiac disturbances.
