This document provides information about the Fabaceae (Leguminosae) family and some crude drugs obtained from plants in this family. It discusses: - The Fabaceae family is one of the largest plant families, including trees, shrubs, herbs and climbers. It is divided into 3 subfamilies. - Cassia, senna, and acacia are some crude drugs obtained from plants in the Fabaceae family. Cassia is obtained from Cinnamomum cassia and is used to treat diabetes. Senna is obtained from leaves and used as a laxative. Acacia gum comes from various Acacia species and is used in medicines, baking, and woodwork

Family & Crude
Drugs

4. Fabaceae (Leguminosae)
The Pea or Bean Family
 Scientific Name : Astragalus australis
Class: Magnoliopsida (dicot)
Sub-Class: Rosidae
Order: Fabales
Family: Fabaceae
 Subfamily:
1. Papilionoideae
2. Caesalpinoideae
3. Mimosoideae

5. • 750 genera
• 19,500 species
• Found all over the world, concentrated in warm temperate regions
in the Northern and Southern Hemisphere (3rd largest family of
flowering plants)
• Geographical range:
North America, Europe, Northwest Asia

6. Habit: These are herbs, shrubs, trees, twiners or climb-errs.
Roots: The roots of many species, particularly of Pap-ilionaceae, have
tubercles.
Leaves: These are alternate, pirnnately compound, and rarely simple, as in
rattlewort (Crotalaria sericea), camel’s foot tree (bauhinid) and some species
of desmodium, e.g. D. gangeticum, with a swollen leaf-base known as the
pulvinus. There are two, usually free, stipules.
Flowers: These are bisexual and complete, regular or zygomorphic or
irregular, and hypogynous or slightly perigynous.
Calyx: There are usually 5 or (5) sepals, with the odd one anterior (away
from the axis). Sometimes there are four sepals. They may be united or free.
Corolla: 5 petals (1 standard, 2 wing, 2 keel)

7. Flower and Corolla:

8. Androecium: There are usually 10 or more stamens (often less than 10 by
reduction) free or united.
Gynoecium: There is one carpel. The ovary is one-celled, with one to many
ovules. It is superior and the placentation is marginal. The ovary often borne on a
long or short stalk is called the stipe or gynophore.
Fruit: This is mostly a legume or pod (dehiscent), or sometimes a lomentum
(indehiscent).
This is the second biggest family among the dicotyledons, and has varying
characteristics. As such, it has been divided into the following sub-families:
Papilionaceae, Caesalpin-ieae and Mimoseae.
The division is primarily based on the characteristics of the corolla and the
stamens.

10. Sub–families
The Family is divided into three sub–
families:
 (a) Papilionaceae
 This sub-family has about 400 genera and 9000 species. The members of this family occur all over the world.
particularly A arm and temperate regions.
 Habit: These are trees. shrubs or herbs.
 Stem: It may be herbaceous. woody or climber with tendrils. Tendrils are wiry. coiled and thread like structure.
