Pharmacognostical Studies on Orilaitamarai -hybanthus Enneaspermus (l) F. Muell-(violaceae)
The paper deals with the detailed pharmacognosy of the whole plant of Orilaitamarai (Hybanthus enneasperms) sold in the local market under the name Purusharatna, Ratanpursuha. The studies include macro, microscopical, histochemical and diagnostic characters of the root, stem and leaf. The physical constants, fluorescence characteristics and chromatographic studies of the whole plant are also pr...
متن کاملHost-Defense Activities of Cyclotides
Cyclotides are plant mini-proteins whose natural function is thought to be to protect plants from pest or pathogens, particularly insect pests. They are approximately 30 amino acids in size and are characterized by a cyclic peptide backbone and a cystine knot arrangement of three conserved disulfide bonds. This article provides an overview of the reported pesticidal or toxic activities of cyclo...
متن کاملDistribution of circular proteins in plants: large-scale mapping of cyclotides in the Violaceae
During the last decade there has been increasing interest in small circular proteins found in plants of the violet family (Violaceae). These so-called cyclotides consist of a circular chain of approximately 30 amino acids, including six cysteines forming three disulfide bonds, arranged in a cyclic cystine knot (CCK) motif. In this study we map the occurrence and distribution of cyclotides throu...
متن کاملEthnobotanical survey of Rinorea dentata (Violaceae) used in South-Western Nigerian ethnomedicine and detection of cyclotides
ETHNOPHARMACOLOGICAL RELEVANCE People living in the tropical rain forest of South-Western Nigeria use Rinorea dentata (P. Beauv.) Kuntze (Violaceae) in ethno-veterinary medicine to facilitate parturition. There are no evidence-based pharmacological investigations for the uterotonic activity of this plant. AIMS OF STUDY (i) Collection of data about the ethnopharmacological uses of R. dentata a...
متن کاملStructure and Activity Studies of Cyclotides STRUCTURE AND ACTIVITY STUDIES OF CYCLOTIDES
This thesis focuses on a large family of cyclic mini-proteins, namely the cyclotides, which have been discovered in a range of plants over the past decade. Around 50 cyclotide sequences have been published to date but the family is estimated to comprise hundreds or thousands of members. Most cyclotides consist of approximately 30 amino acids and have a unique and extremely stable three-dimensio...
