BACKGROUND AND AIMS Fritillaria-type female gametophyte development is a complex, yet homoplasious developmental pattern that is interesting from both evolutionary and developmental perspectives. Piper (Piperaceae) was chosen for this study of Fritillaria-type female gametophyte development because Piperales represent a 'hotspot' of female gametophyte developmental evolution and have been the s...
The antifungal effect of 10 plant extracts viz., Thevetia peruviana, Ocimum basilicum, Piper betel, Murraya koenigii, Chrysanthemum coronarium, Polyalthia longifolia, Catharanthus roseus, Pelargonium graveolens, Moringa officinalis and Lawsonia inermis were evaluated by poisoned food technique against Rhizoctonia solani Kuhn, the causal organism of sore shin disease of tobacco. Among all the pl...
OBJECTIVE To study the reliability of a proving methodology and the reproducibility of proving symptoms. METHODS Two homeopathic medicines and placebo were given, in a double-blind randomized design, to 31 healthy volunteers (13 Piper methysticum 30C, 11 placebo and 7 Plumbum metallicum 30C), 5 drops 4 times daily, until the onset of unbearable symptoms, or at most for 1 week. The primary out...
The mosquito Aedes aegypti is the vector of the dengue virus, an endemic arbovirus from tropical and subtropical regions of the world. The increasing resistance of mosquitoes to commercial insecticides impairs regular control programs; therefore, chemical prospecting originating from the Amazonian flora is promising for potential new insecticides. Several Piper species are, notably, rich in phe...
ion of a hydrogen atom from poly unsaturated fatty acids (PUFA); the hydroxyl radical is capable of starting this reaction sequence [4, 5]. While Piper species are reported to have wide spectrum of biological activity but its antioxidant potential has not been established so far, making it important and interesting to analyze the antioxidant potential of Piper betle leaf extract in the present ...
Mexican sunflower is native to Mexico and Central America and was introduced into China early last century. Now it has widely naturalized and is exhibiting increasing invasiveness in South China. As this species often dominates bare ground, a habitat characterized by extreme fluctuation in temperature and water, it is reasonable to hypothesize that it has special adaptations to high temperature...
Petioles of the plant piper betle-bengal variety have been subjected for extraction employing standard procedure and the crude extract obtained has been evaluated for its diastase like activity and other physico-chemical properties to investigate further its possible biological and pharmacological activities.
The induction of apoptosis by Piper betel leaf extracts during 7, 12 dimethylbenz [a] anthracene (DMBA) induced hamster buccal pouch (HBP) carcinoma was studied in male Syrian hamsters using DNA fragmentation and the apoptosis-associated proteins, tissue transglutaminase (tTG) and Bcl-2. Hamsters were divided into four groups of six animals each. Animals in group 1 were painted with a 0.5% solu...
