Classification of Plants Based on Ecology, Medicinal Values and Pharmaceutical Properties Flashcards
examines the
relationships between plants and their
physical and biotic environment
Plant ecology
Plants are mostly _______ and
photosynthetic organisms, and must
attain their light, water, and nutrient
resources directly from the immediate
environment.
sessile
Plants synthesize hundreds of chemical
compounds for functions including defense
against _______, _____, ________, and
___________ _______.
insects, fungi, diseases, and
herbivorous mammals
Numerous _____________ with potential or
established biological activity have been
identified. However, since a single plant contains
widely diverse these are, the effects of
using a whole plant as medicine are uncertain.

A ________ _____ is a plant that is used with the
intention of maintaining health, to be administered
for a specific condition, or both, whether in modern
medicine or in traditional medicine
medicinal plant
produced during secondary vegetal metabolism are usually responsible for the biological properties of some plant species used throughout the globe for various purposes, including treatment of infectious diseases
Active compounds
Natural products are often divided into two major classes:
- Primary metabolites
- Secondary metabolites
organic molecules that have an intrinsic function that is essential to the survival of the organism that produces them (i.e. the organism would die without these metabolites)
Primary metabolites
Core building block molecules (nucleic acids, amino acids, sugars,
and fatty acids) required to make the major macromolecules
(DNA, RNA, proteins, carbohydrates, and lipids) responsible for
sustaining life.
examples of primary metabolites
organic molecules that typically have an extrinsic function that mainly affects other organisms outside of the producer
Secondary metabolites
Secondary metabolites are ___ _________ __ ________ but do
increase the competitiveness of the organism within its
environment.
not essential to survival
examples of secondary metabolites
- Alkaloids
- Phenylpropanoids
- Polyketides
- Terpenoids
- Flavonoids
- Isoprenoid
bitter-tasting chemicals, very widespread in
nature, and often toxic, found in many medicinal plants
Alkaloids
secondary metabolites that contain nitrogen as a
component of their organic structure
Alkaloids
- Atropine
- Scopolamine
- Hyoscyamine
- Berberine
- Caffeine
- Cocaine
- Ephedrine
- Morphine
- Nicotine
- Reserpine
- Quinidine
- Vincristine
are examples of?
Alkaloids
Found in medicinal plants
such as rhubarb, cascara, and Alexandrian senna.
Plant-based laxatives made from such plants include
senna, rhubarb and Aloe.
Anthraquinone glycosides
- powerful drugs from medicinal plants including foxglove and lily of the
valley - include digoxin and digitoxin which support
the beating of the heart, and act as diuretics
cardiac glycosides
widespread in plants, having diverse roles in defenses against plant diseases and predators
Polyphenols
They include hormone-mimicking phytoestrogens and astringent
tannins.
Polyphenols
Plants containing phytoestrogens have been administered for
centuries for gynecological disorders, such as _________, ________,
and __________ _______.
fertility, menstrual, and menopausal problems
Many ____________ ________, such as from grape seeds, olives or
maritime pine bark, are sold as dietary supplements and cosmetics
without proof or legal health claims for beneficial health effects.
polyphenolic extracts
a diverse family of organic compounds that are synthesized from the amino acids phenylalanine and tyrosine
Phenylpropanoids
one of the volatile flavor molecules found in cinnamon is a phenylpropanoid
Cinnamic acid
assembled from the building blocks of acetate
and malonate to form large, complex structures
Polyketides
a polyketide structure produced by fungi from
the Aspergillus genus
Alflatoxin B1
constructed from 5-carbon monomer units called isoprene
Terpenoids
is assembled from multiple repeating isoprene units
Natural rubber
found in a variety of medicinal plants and in resinous plants such as
the conifers
Terpenes and terpenoids
strongly aromatic and serve to repel herbivores
Terpenes
Their scent makes them useful in essential oils, whether
for perfumes such as rose and lavender, or for
aromatherapy.
Terpenes
is an antiseptic and was once used as a vermifuge (anti-worm
medicine)
thymol (example of terpenes)
