Persea americana fruit and leaves had been known in folk medicine for their anti-diabetic prowess. Therefore, this study sought to investigate the inhibitory effect of phenolic extract from avocado pear (Persea americana) leaves and fruits on some key enzymes linked to type 2 diabetes (α-amylase and α-glucosidase); and sodium nitroprusside (SNP) induced lipid peroxidation in rats' pancreas in v...

BACKGROUND Nerium oleander L. (syn. Nerium indicum Mill, Nerium odorum Aiton) belongs to the family Apocynaceae. It is used for its anti-inflammatory, anti-diabetic, anti-cancer and hepatoprotective activities in traditional medicine. Previous pharmacognostic studies suggested that 70 % hydro-methanolic extracts of oleander possess potent free radical scavenging and anti-inflammatory activities...

Abstract Shellac, the purified resin produced from female lac bug (Kerria lacca), has its application within a wide range of industries, including healthcare, food, wood treatments and cosmetics. Shellac 20% alcohol is included in British Society for Cutaneous Allergy/European Contact Dermatitis extended facial series based on frequency reactions exceeding 0.3% threshold. However, source primar...

Background & Aim:  Acorus calamus L. (Araceae) is an herb traditionally used in Indian and Chinees system of medicine. It is a perennial herb with long, cylindrical scented rhizomes which are creeping and extensively branched with the thickness up to 2.5 cm. The rhizomes are whitish internally and brownish externally in appearance. It is vernacularly known as ...

propane units, is an agglutination element in the cell wall of vascular plants. These units are referred to as guaiacyl (a), syringyl (b), and p-hydroxyphenyl, (c) phenyl-propane units (Fig. 1). They are connected in three-dimensional space by C–C and C–O–C bonds. Softwood lignin consists of (a), hardwood lignin of (a) and (b), and herb lignin of (a), (b) and (c). Lignin is taken up as a “dieta...

The regeneration of alpha-tocopherol (vitamin E; VE) by coantioxidants such as phenolics and ascorbate has been studied in homogeneous hydrocarbon solution and in biological systems. However, VE phenoxyl radicals (VE*) may be sufficiently reactive to cooxidize phenolic compounds and ascorbates. The coantioxidant behavior of some relevant phenols such as eugenol (EUG), isoeugenol (IsoEUG), 2,6-d...

Phosphoinositide signaling, in particular, phosphoinositide 3-kinase (PI3K) signaling, has been implicated in mediating inhibitory odorant input to mammalian olfactory receptor neurons (ORNs). To better understand this phenomenon we investigated PI3K-dependent inhibition between single odorant pairs. The concentration-dependent inhibition of the response of native rat ORNs to octanol by citral ...
