primula palinuri/抗氧化剂

In the present study, 2,2-diphenyl-1-picrylhydrazyl radical scavenging, α-amylase and α-glucosidase inhibition activities, and total phenolic contents of n-hexane, ethyl acetate, and methanol extracts of various parts of Allium paradoxum, Buxus hyrcana, Convolvulus persicus, Eryngium caucasicum,

BACKGROUND The genus Primula (Primulaceae) has been used in traditional medicine to treat convulsion and microbial or viral infections. OBJECTIVE In the present study, we evaluate antioxidant, antihemolytic, and protective effects of flavonoid-rich fractions of endemic Primula heterochroma Stapf.

Different parts of three plants (Primula auriculata, Fumaria vaillantii and Falcaria vulgaris) were extracted with three different solvents to yield 72 crude extracts. The phytochemical analysis (chemical screening, GC-MS) of three plants was investigated for their antioxidant and antibacterial

In recent years, considerable attention has been paid to plants as potent natural drugs for their ameliorative roles against free-radical-mediated oxidative stress. Therefore, their interactions with cell membrane lipids and proteins, which generally serve as primary targets of lipid peroxidation,

Protocorm-like bodies (PLBs) of Brassidium Shooting Star orchid were successfully cryopreserved using droplet-vitrification method. Vitrification based cryopreservation protocol is comprised of preculture, osmoprotection, cryoprotection, cooling, rewarming, and growth recovery and each and every

The biological effects of epicuticular substances in farinose exudates accumulated on inflorescence shafts and calyces of Primula denticulata on human acute myeloid leukemia cells (HL-60) were analyzed. The crude material possessed little antioxidative capacity but strong cytostatic properties. Some

Primula heterochroma is indigenous to Caspian coast forests in the north of Iran. Total phenols, total flavnoids, total carotenoids and antioxidant capacity of 50 P. heterochroma accessions were investigated. The highest total phenol (1272.31 mg GA equivalent/100 g fresh weight) and total flavonoids

Primula veris L. and Primula elatior (L.) Hill represent medicinal plants used for the production of herbal teas and preparations with antioxidant and expectorant activity. Flowers and roots of both species possess the same biological activity. In the presented study, raw materials of wild growing

Chronic obstructive pulmonary disease (COPD) is a disease that affects the lungs and is defined by a variety of symptoms that combined with co-morbidities lead to a decline of the patients quality of life. The principal etiology of chronic obstructive pulmonary disease is smoking and air pollution
