TITLE Herb Science and Natural Products

 
LEVEL 03 - Years 2, 3, 4 in Modular Undergraduate Course

 
ECTS CREDITS 4

 
DEPARTMENT Rural Sciences and Food Systems

 
DESCRIPTION This study-unit is composed of three parts:

Part 1 deals with the utilisation of plants in different cultures, termed as ethnobotany; the systematics of plants with ethnobotanical uses;

Part 2 deals with the phytochemistry of plants primarily metabolism in plants; primary metabolites (carbohydrate, lipids, proteins); secondary metabolites (terpenoids, flavonoids, tannins, alkaloids); pathways for metabolic production;

Part 3 deals with cultivation practices related to secondary-metabolite yielding plants, with elements of HACCP (Hazard Analysis Critical Control Point Systems); use of fertilisers, pesticides, different propagation methods, soil quality and water regimen, environmental parameters, contributing towards secondary metabolite product; herbaria and botanic gardens.

Study-unit Aims

The main aim of this study-unit is to introduce the concept of the utilisation of plants other than for culinary purposes. The student will recognise the importance of several environmental and agronomic parameters on the production of compounds with medicinal and cosmetic properties in plants.

Learning Outcomes

1. Knowledge & Understanding: By the end of the study-unit the student will be able to:

1) define ethnobotany and discuss the methodology used in this field;
2) name and describe the main families of the Plant Kingdom in particular Asteraceae, Lamiaceae, Rosaceae, Fabacaea, Lilaceae, Cucurbitacae amongst others;
3) relate structure to function for the main families;
4) distinguish between primary and secondary metabolism in terms of role and complexity within the plant species;
5) distinguish the utilisation of plant species to humans with respect to primary and secondary metabolites;
6) compare and contrast metabolites falling under different phytochemical classes particularly terpenoids, alkaloids, flavonoids and shikimate products, tannins, proteins, organic acids, non-flavonoid polyphenolics;
7) distinguish between in vivo (cultivation) and in vitro (micropropagation) practices for typical plants;
8) demonstrate that different cultivation parameters may yield a different quality/quantity of secondary metabolites;
9) distinguish between in situ and ex situ conservation;
10) recognize the importance of herbaria.

2. Skills: By the end of the study-unit the student will be able to:

1) apply the principles of ethnobotany and devise a protocol for a specific useful plant;
2) identify plants, particularly those falling within the major families of the Plant Kingdom;
3) classify any given compound as a primary or secondary metabolite;
4) categorise specific compounds into phytochemical classes;
5) devise a cultivation plan for a specific plant species;
6) determine whether a plant is suitable for cultivation and/or micropropagation;
7) plan and organise a herb garden for demonstration purposes.
