ABSTRACT
SRIHARIKOTA acquired importance botanically because of rich
Introduction
Yanadies an aboriginal tribe are in
Until the establishment of SHAR Centre at Sriharikota, yanadies used to live in forests and near sea coast in traditional way, drifted from the natural way of life due to agro-rural developmental activities a few aged tribal men are able to furnish ‘ethno-medicinal data’ pertaining to their traditional practices and healings. With the help of local tribal men, 300 ethnomedicinal plants are recorded. Based on their pharmaceutical uses they are classified into 16 – categories [Annexure II ].
Out of 300 species surveyed 21 samples falling under 6 –categories are selected for phytochemical screening. Out of them 14 species are endemic/rare. The results are discussed in detail in this article.
Topography
Materials and Methods
Intensive medico-ethnobotanical survey is conducted in Sriharikota Island for 3 years since 1996-99.Field tours at regular intervals were conducted covering all the seasons so as not to miss seasonal elements having pharmaceutical value. Plants are selected for phytochemical screening are popularly used by tribals for their general ailments [Annexure 1].
Phytochemical screening was done by the standard procedures prescribed by Bhattacharya (1956), later modified by Chhabra et.al (1984) and Harborne (1973, 1977).
Preparation of Extracts
The plant parts (root bark, stem, leaf and whole plant etc.) were washed with water, chopped into small fragments and shade dried. The dried samples were ground to power (each 200 gr.) and stored in polythene containers at room temperature. These samples are used for screening to detect the different classes of chemical constituents.
Extracts
of sample are prepared by taking of 20 gr. of sample in 200 ml. methanol. Each
sample is tested for 11 components Results are given in Annexure I.
16 Field tours of 5-7 days duration of each tour are conducted for three years during 1996-99. with the assistance of local tribal men. 300 species having medicinal uses and ample field notes also are collected regarding flowering, fruiting, flower colour and smell etc; phenological data. Further data pertaining to ethnomedicinal information of each species also recorded. 21 plant samples are choosen for phytochemical screening based on their popular pharmaceutical importance, coupled with their endemic or rare in occurrence.
Active constituents present in the plant species in different plant parts (root bark, stem, whole plant, leaves etc.) are responsible for their therapeutic effects. A preliminary phytochemical analysis is conducted to detect the presence of alkaloids, saponins, tannins, carbohydrates, proteins, steroids, trterpinoids, amino acids etc., which act as possible curing agent during folk therapy.
Tests are conducted for 11 components as detailed in the Annexure-I. Their occurrence in noted with symbol (+)in the table given total number of components present in each sample is given in the last column (17) in parenthesis. The table also contains tribal medicinal uses and other folklore medicinal uses, so as to relate medicinal properties with the components of positive occurrence. Further these samples also grouped into 6 broad pharmaceutical categories as given in Annexure-II. Results of the tests for chemical constituents of each of the pharmaceutical group are discussed in detail, here under.
P.C. No. 5: RHEUMATISM
Seven test samples have PC 5 property based on their tribal /folklore medicinal use.
Upon chemical analysis five components viz. alkaloids, flavonoids, phenols, amino acids, steroidal nucleus are positive in variable combinations in 7 samples. Saponins occur in 4 samples, tannins occur in 2 samples.
Presence of alkaloids, flavonoids, phenols, amino acids, steroidal nucleus in the samples consistently in variable combinations and minimum of two components positive for any 2 samples is indicative of having curative effect for PC 5 either individually or cumulatively
PC No. 7: SEXUAL PROBLEMS
4 samples positive for alkaloids (t 6)
Flavonoids (t 7), phenols (t 8), saponins (t 9) and steroidal nucleus (t 15) are positive for 3 samples out of 4 tested samples variably.
Thus alkaloids seems to have curative effect in combination with flavonoids, phenols, saponins and steroidal nucleus for PC 7.
PC No. 8: SKIN & DERMATITIS
2 samples when tested, out 11 components resulted positive for four tests i.e., t 7, 8, 9, and 15 viz. flavonoids, phenols, steroids/triterpinoids and steroidal nucleus.
PC NO. 9: OPTHALMIC &
5 samples are reported for PC 9
All the 5samples are positive for flavonoids (t7) where as 3 samples are positive in variable order for alkaloids (t 6), phenols (t 8), saponins (t 9) and tannins (t 10).
All the 5 components occur in 1 sample i.e., Eugenia
bracteata.
Thus flavonoids (t7)
seem to be curative component either indivially as in
Capparis brevispina or cumulatively
in other samples.
PC No. 13: Cooling and Alterative
1 sample – Colubrina asiatica shown positive for t 7, t 9, t 13, and t 15.
PC No.16: Diabetes
1 sample tested for 11 components. Interestingly it is positive for 9 components. T 12 and t 16 are negative. Out of nine components which of them is specific curative is not certain for PC 16.

Conclusion
21 Phyto-samples falling under 6 pharmaceutical categories are investigated for 11- chemical components. Results obtained are analysed to note that the presence of specific classes of chemical constituents are in confirmity with the tribal medico-therapy, given in Annexure –II.
Further it is interesting to note that 14 samples out of 21 belong to endemic/ rare species. In view of Endemism/Rarity of the species chosen for phytochemical analysis, these specimens need further investigation to detect specific active principles of curative effect.
