Eleven hydroxycinnamic acid derivatives were isolated from a 70% methanolic Crataegus extract (Crataegi folium cum flore) and partly verified and quantified for individual Crataegus species (C. laevigata, C. monogyna, C. nigra, C. pentagyna) by HPLC: 3-O-(E)-p-coumaroylquinic acid (1), 5-O-(E)-p-coumaroyl-quinic acid (2), 4-O-(E)-p-coumaroylquinic acid (3), 3-O-(E)-caffeoylquinic acid (4), 4-O-...

Crataegus spp. are used for horticultural and medicinal purposes. The medicinal importance of Crataegus is attributed to components such as flavonoids, procyanidin, aromatic acid, and cardiotonic amines. The genetic relationships among the five Iranian Crataegus species including C. aronia, C. pontica, C. meiery, C. monogyna, and C. pentagyna were assessed using inter simple sequence repeats (IS...

long exposure of uv radiation increases risk of skin diseases such as cancer and photoallergic reactions. uv-b (280-320 nm) radiation is mainly responsible for inducing skin problems. skin protection is a suitable method in the fight against ultraviolet radiation induced damage. various synthetic agents have been used as photo protective but because of their potential toxicity in humans, they h...

Morphological, numerical and chemical taxonomy of the genus Crataegus was studied in the East and northeast of Iran. More than 80 fresh specimens as well as 50 herbarium specimens from different localities were examind. Using vegetative and reproductive morphological characters an identification key is provided for all taxa. For numerical taxonomy 85 morphological characters were measured and t...

Considering the importance of natural products in cancer therapy, a preliminary investigation on some anticancer medicinal plants of north-eastern states of India was conducted in murine tumor model. Nine different plants such as Ageratum conizoides Linn. (Asteraceae), Blumea lanceolaria Linn. (Asteraceae), Dillenia pentagyna Roxb. (Dilleniaceae), Potentilla fulgens Wall. (Rosaceae), Taxus bacc...

Long exposure of UV radiation increases risk of skin diseases such as cancer and photoallergic reactions. UV-B (280-320 nm) radiation is mainly responsible for inducing the skin problems. Skin protection is a suitable method against ultraviolet radiation-induced damage. Various synthetic agents have been used as photo protective but because of their potential toxicity in humans, they have limit...
