GROWTH REGULATORY ACTIVITIES OF SOME FRUIT LEAVES AND CHEMICAL INVESTIGATIONS ON THE LEAVES OF Dillenia indica
Collections
Abstract
An experiment was conducted on naturally occurring growth substances in aqueous
extracts of some common fruit plant leaves viz., Mango (T2), Black berry (T3), Jack fruit
(T4), Litchi (Ts), Wood apple (T¢), Indian dillenia (T7), Papaya (Ts) , Banana (To), Guava
(Tio), Olive (T;1) for each vegetable crops such as Country bean, Yard long bean, Okra
and Swamp cabbage with the attempt for chemical investigation on effective leave
extract. The aqueous extracts of Indian dillenia (Dillenia indica) significantly increase
germination of Country bean, Yard long bean bean, Okra and Swamp cabbage seeds
compared with control. The highest germination percentage consequently 100%, 99%,
73% and 60% in Country bean, Yard long bean bean, Swamp cabbage and Okra in seeds
treated with Indian dillenia compared with control. The effect of aqueous extract of
Indian dillenia (Dillenia indica) showed the positive regulatory effect, i.e., increased
growth of root and shoots length of Country bean, Yard long bean, Okra and Swamp
cabbage seedlings.
The Thin Layer Chromatography (TLC) examination of chloroform extracts of Indian
dillenia (Dillenia indica) was showed four distinct compounds at Hexane: Ethylacetate
(9:1, v/v,). Crude compounds were purified and isolated by column chromatography.
One of them initially was indicated steroid type compound by Liberman-Berchand
reaction. 'H-NMR and IR study were indicated that the fractions were probably steroid
and triterpinoid types compounds which were discussed in details in result and
discussion.
