3. Terpenoids shows biological activity like
insecticidal,anthelmintic and antiseptic action thus
useful in pharmacy.
01 INTRODUCTION
Most of the terpenoids are colourless fragnant liquids
which are lighter than water & volatile with steam.
All are soluble in organic solvent & usually insoluble
In water .most of them are optically active.
4. D e f i n a t i o n o f Te r p e n o i d s
Terpenoids are the phyto constituent which are
derived from two or more isoprene molecules.

Name of terpenoids
1.Monoterpenoids
2.Sesquiterpenoids
3.Diterpenoids
4.Triterpinoids
5.Polyterpenoids
7. 2.Sesquiterpenoids
They are known as C-15 compound because they have molecular formula
...........They are optically active & are found in highest boiling point fraction
of volatile oil e.g.
Sr.No. Constituent Drugs
1 Caryophyllene Clove, copaiba
2 Santalene Sandel woo
3 Bisobolene Lemon oil
4 Cadinene Lemon oil
5 Gossypol Cotton plant
11. Identification test
There are different method for isolation and specific chemical test for
Identification of Individual constituent depending upon the
chemical group to which they belong like alkaloids, glycoside,
saponins , volatile oil,Resins etc.
