Title:Mechanism of Piper laetispicum extract (EAE-P) during Chronic Unpredictable Mild Stress is mediated by the interrelationship of inflammatory cytokines, apoptosis cytokines and neurotrophin in the hippocampus

Thailand is located in the tropical rain forest zone above the equator. This geographically supports very rich biodiversity, including the genus Piper (Piperaceae). Thirtyeight species of Piper, from out of over 1,000 species in the world, have been discovered recently (1998-2006) by the authors. Plant morphology and plant use information were recorded via observation, market surveys, and inter...

INTRODUCTION The phytochemistry of species of the genus Piper has been studied extensively, including Piper solmsianum. However, no studies have addressed the phytochemistry of the sap content of Piper species. OBJECTIVE To evaluate the transferring of secondary compounds from the saps of P. solmsianum to the honeydew of Edessa meditabunda. METHODOLOGY The honeydew of E. meditabunda and sap...

background: the fracture healing is impaired in osteoporosis. piper sarmentosum is a plant, which contains potent antioxidant, naringenin that may enhance fracture healing. the present histological study aimed to determine the effects of water extract of piper sarmentosum on the late phase of fracture healing in estrogen-deficient rats. methods: twenty four female sprague-dawley rats (200-250 g...

OBJECTIVE The aim of this study was to determine the erythrocyte antioxidant enzyme activity and the superoxide dismutase, catalase, glutathione peroxidase, and plasma malondialdehyde levels in aging mice and to evaluate how these measures are modulated by potential antioxidants, including the tocotrienol-rich fraction, Piper betle, and Chlorella vulgaris. METHOD One hundred and twenty male C...

Exhaustive hydro-distillation of the leaves of Piper aduncum and fruits of Piper gibbilimbum (Piperaceae) afforded colorless and pale orange colored oils in 0.35 and 0.30 % yields, respectively. Detailed chemical analysis by GC/MS indicated the volatile constituents of Piper aduncum to be composed of dill apiole (43.3%), beta-caryophyllene (8.2%), piperitione (6.7%) and alpha-humulene (5.1%), w...

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...
