This paper proposes a novel energy-efficient oil shale pyrolysis process triggered by a topochemical reaction that can be applied in horizontal oil shale formations. The process starts by feeding preheated air to oil shale to initiate a topochemical reaction and the onset of self-pyrolysis. As the temperature in the virgin oil shale increases (to 250-300°C), the hot air can be replaced by ambie...

The antioxidant capacity of Ocotea tampicensis (Meissner) Hemsley, Bursera simaruba (L.) Sarg, Pseudobombax ellipticum (Kunth) Dugand, Hamelia patens Jaqc and Croton reflexifolius Kunth was evaluated. Ethanolic and aqueous extractions were performed at concentrations of 15, 30, 60, 120 and 240 mg / 100ml. Colorimetric tests ABTS, DPPH and FRAP were used. The results were expressed as equivalent...

Shengfu oil is a traditional Chinese medicine formula containing 16 ingredients, including Scutellariae radix, Olibanum, and Rehmanniae radix. In this study, we aimed to enhance the wound healing of rabbit full-thickness scalded skin by Shengfu oil and to elucidate its regulatory effects on β-catenin, Dlk1, and COX-2. We found that Shengfu oil exhibited significant anti-inflammatory, analgesic,...

BACKGROUND Bursera morelensis, known as "Aceitillo", is an endemic tree of Mexico. Infusions made from the bark of this species have been used for the treatment of skin infections and for their wound healing properties. In this work, we present the results of a phytochemical and antimicrobial investigation of the essential oil of B. morelensis. MATERIALS AND METHODS The essential oil was obta...

In order to find and develop new botanical pesticides against tobacco storage pests, bioactivity screening was performed. The essential oil obtained from the aerial parts of Liriope muscari was investigated by GC/MS and GC/FID. A total of 14 components representing 96.12% of the oil were identified and the main compounds in the oil were found to be methyl eugenol (42.15%) and safrole (17.15%), ...
