“…Its continental range extends from regions of North Africa Morocco, Algeria, Tunisia, and Libya and the Middle East Syria, Lebanon, Jordan, Palestine, and Turkey up to Southern Mediterranean regions in Europe 9 Eastern Greece, Croatia, Northern Italy, Eastern France and Eastern Spain . Previous photochemical studies concerned with this species focused on the phenolic compounds of the needles of the plant 10 , the oil seeds 11 , the organic compounds of stems and roots 12,13 , the lipid portion of the pollen grain as well as the volatile compounds including essential oils obtained from needles 14,15 .…”

Compared to normal, diabetic skin is characterized by great sensitivity. Oxidative stress is directly involved, contributing to accelerated skin aging, xerodermia and poor wound healing. In the last 10 years, cigarette smoke (CS) exposure has been associated with several skin and dermatological conditions and is directly related to the oxidative stress affecting the skin. However, limited data exist concerning the effect of CS on diabetic skin. Some of the effects of cigarette smoke exposure on the skin of hairless diabetic mice were hereby studied and the potential skin protection by topical applications of Pinus halepensis bark extract was investigated. Female hairless SKH-2 diabetic mice were exposed for 8 days to tobacco smoke and topical applications were performed twice daily. Biophysical parameters such as transepidermal water loss (TEWL), skin elasticity and erythema were measured. In addition, the oxidative stress was evaluated. The results show that diabetes and CS have a synergistic negative action on skin condition, with the development of xerosis and high ROS levels whilst topical applications of Pinus halepensis bark extract protect efficiently the toxic effect of CS on skin, by decreasing skin dryness, oxidative stress and blood glucose levels.

ABSTRACT:To establish parameters for quality control of Morus alba leaves were done tests of purity by determining the loss on drying, foreign matter, total ash, acid insoluble ash, swelling index, bitterness index, yield of crude extract, pH and organoleptic properties. The tests were done with samples collected on March, June, September and December according to Brazilian Pharmacopeia and World Health Organization. The percentage of loss on drying found are according to the established value of 14 %, the highest content was on September 12.89 ± 0.1400 %. The indices of foreign matter found are agreement with the amount allowed by Brazilian Pharmacopeia, which establishes a maximum of 2 % for most of the herbal drugs. The colletc on March showed the highest content of total ash and acid insoluble ash, respectively, 20.48 ± 0.3517 % and 5.68 ± 0.1057 %. The swelling index showed higher values in samples collected on September 7.95 ± 0.2186 mL and on December 7.1 ± 0.8544 mL. The bitterness index was higher in the first two collections, 1.037 units/g in both. The yield produced was 18 % on March, 29.61 % on June, 26.47 % on September and 24.35 % on December. The pH of aqueous extract was neutral (pH 7.0) on March and slightly acid (pH 6.0) in other months. The four collect showed small variations in relation the organoleptic properties. It was done dosage of total polyphenols and flavonoids with 70% ethanol extracts of M. alba leaves. The content found of polyphenols were 6.467 ± 0,012; 5.503 ± 0.007; 6.016 ± 0.020; 6.943 ± 0.046 milligrams of gallic acid per gram of dried plant on March, June, September and December, respectively. The content of flavonoids found were 4.345 ± 0.008; 3.782 ± 0.016; 4.362 ± 0.005; 4.893 ± 0.013 milligrams of rutin per gram of dried plant. Descriptors: Morus alba;
