CHEO8002 - Pharmacognosy & Phytochemistry

Title:Pharmacognosy & Phytochemistry
Long Title:Pharmacognosy and Phytochemist
Module Code:CHEO8002
Duration:1 Semester
Credits: 5
NFQ Level:Advanced
Field of Study: Biochemistry & Cell Biology
Valid From: Semester 1 - 2016/17 ( September 2016 )
Module Delivered in 1 programme(s)
Module Coordinator: Brigid Lucey
Module Description: The main aim of this module is to investigate therapeutic functions and interaction of plant chemicals and the metabolic pathway leading to their biosynthesis. Plant constituents organised into chemical groups and functions will be described with examples derived from medicinal plants with outline of their properties and activity.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Recognise molecular structures of main classes of phytochemicals and of their derivatives
LO2 Explain metabolic pathways leading to biosynthesis of various classes of natural products.
LO3 Perform extraction and characterisation of main phytochemicals
LO4 Discuss the therapeutic actions of main classes of phytochemical and their interactions with other herbs or drugs.
LO5 Critically evaluate the use of plant and plant products as medicinal agents
Pre-requisite learning
Module Recommendations

This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).

Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed
Co-requisite Modules
No Co-requisite modules listed

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
