Plant exudates are fluids emitted through pores or wounds that consist primarily of secondary metabolites with no physiological role for the plant. They include natural resins from plants as well as synthetic resins, and come in different forms such as gums, latex, juices, and extracts. Gums are abnormal products from trees and shrubs, latex is a milky emulsion drawn from plant bark, juices come from fruits and leaves, and extracts involve chemically or mechanically obtaining active constituents from plants for uses including food, medicine, and manufacturing materials like rubber.

1. PLANT
EXUDATES

2. An exudate is a
fluid emitted by
an organism
through pores or
a wound.

4. • They are the solid or
semi solid hydrocarbon
secretions of plant.
•Consist primarily of
secondary metabolites,
have no role in
physiology of plant

5. NATURAL RESINS
product which
comes from a
plant
SYNTHETIC RESINS
They required pigments to be
grinded, which provides
excellent transparency and
pigment wettinge.g. galbanum, myrrh ,
asafetida

6. GLYCO RESINS:
GLYCO RESINS Glycosidal combinations of resins which upon hydrolysis
yield sugar and complex resin acids
E.g.: Jalap, Ipomoea
OLEO RESINS:
OLEO RESINS Mixtures of volatile oil and resinous substances
E.g.: Turpentine
OLEO-GUM RESINS:
OLEO-GUM RESINS Mixtures of volatile oil, gum and resinous substances
E.g.: Myrrh
BALSAMS:
BALSAMS Resins in combination with benzoic or cinnamic acid
E.g.: Benzoin

8. USES
•Mucilage is
mixed with
water is used
as glue
EXAMPLE
•Aloe-
Vera
cactus
MEDICINAL
USES
•Protection of plant
wound

10. Solubility: insoluble in
alcohol and soluble In
water
General character:
Amorphous
Examples: gum ghatti
acacia
Chemically: consists of
Ca, K, Mg
GUMS
obtained from
trees and shrubs,
and are the
abnormal
products

12.  The latex is a
sticky, milky
colloid drawn off
by making
incisions into the
bark and
collecting the fluid
in vessels in a
process called
"tapping“
Latex is a thick, creamy
white, milky emulsion,
although sometimes it may
be a thin, clear, yellow or
orange, aqueous suspension
It has many uses;
from clothing to
paint, ,rubber, is
used in the
manufacturing of
natural latex
mattresses, beauty
application pads,
and cushioning

14.  These juices are obtained from fresh fruit and fleshy
leaves
 they may be used
directly as teas or in other
extracted form for their
natural chemical
constituents
 used as agents in the
synthesis of drugs

16.  To obtain from a substance by chemical or
mechanical action as by pressure , distillation
or evaporation .
 Purpose or use of extract :- Plant extracts have
been shown health promoting properties.
 Example:- The water insoluble residues of
some fruits n vegetables such as oranges ,
carrots , yellow red pepper & tomatoes were
extracted with n-hexane , dichloromethane ,
acetone etc by means of carbohydrate as source
of food.
