  1. A Comparative Phytochemicaland Physicochemical Evaluation: Tikta-anguna, Kiri-angunaand Jeewanti Sujatha Hewageegana Menuka ArawwawalaAnurakumara TisseraSami Ariyawansa Induragare Dammaratana

  2. Introduction Objectives Materials and Methods Results Conclusion

  3. Introduction Tikta-anguna and Kiri-anguna (Behet anguna) Both come under one botanical name - Wattakaka volubilis (Linn.f) Family: Asclepiadaceae • Both creepers are large twining shrubs, with long glabrous branches, Leaves thin, ovate 1.Bitter variety 2. Sweet variety

  4. Wattakaka volubilis Tikta anguna Kiri anguna (Behet anguna)

  5. Parts Used: • Leaves, roots and tender stalks are used • Actions and common uses: • Leaves are used for boils and abscesses as an application • Roots and tender stalks are used for expectorant properties in Ayurveda and traditional medicine • Lactogenic • Aphrodisiac • Sweet variety –cooling and Tonic

  6. Jeewanti Leptadenia reticulate (Retz) Wight and Arn. Family : Asclepiadaceae A much - branched twining shrub, branches numerous and younger ones glabrous, Leaves thin, ovate

  7. L. reticulate • Parts Used: Both roots and leaves Actions and common uses: Both roots and leaves - Skin infections, wounds Leaves - cough, as a respiratory stimulant, Lactogenic Aphrodisiac Cooling and Tonic

  8. Research background : Ayurvedic texts contain lot of simple and effective as well as both externally and internally used medicinal preparations, containing Jeewanti(L. reticulata) Jeewanti is found in most parts of India, but it is not available in Sri Lanka We had to find a most suitable substitute for Jeewanti

  9. According to literature survey and the conversation with Senior Scientist in charge, Haldummulla Research Gardens, we were able to find morphologically, nearly similar two plants (Tikta-anguna and Kiri-anguna) for Jeewanti • In addition, they have similar practices for disease conditions

  10. Comparison of the Two plants L. reticulate and W. volubilis

  11. Purpose of this study was to investigate the possibility of using Tikta-anguna and Kiri-anguna as substitutes for Jeewanti

  12. Objectives • To compare the phytochemical parameters of W. volubilis(Tikta-anguna and Kiri-anguna) and L. reticulata(Jeewanti) • To compare the physicochemical parameters of W. volubilis(Tikta-anguna and Kiri-anguna) and L. reticulata(Jeewanti) • To compare the fingerprint profiles of W. volubilis(Tikta-anguna and Kiri-anguna) and L. reticulata(Jeewanti)

  13. Materials and Methods W. volubilis (both varieties) were collected from Colombo, Sri Lanka Authentication was done by Scientist , Botany Division, BMARI, Navinna, Maharagama Voucher specimen No : W 2561 L. reticulata was collected from Jamnagar, India Authentication was done by Botanist, Vidyaratnam Foundation (Research and Development Section), Thrissur, Kerala, India, according to the standards of Ayurveda Pharmacopeia in India

  14. Plant materials • Plant materials (leaves with tender stalk) were shade dried and cut into small pieces Then prepared the powder using the grinder • Materials were kept in air tight containers until used

  15. Screening of Phytochemical compounds • Presence /Absence of • Phenolic compounds Flavanoids Tannins • Coumarins • Alkaloids • Saponins • Steroid glycosides

  16. Determination of physicochemical parameters Physicochemical parameters were evaluated according to WHO standards

  17. Extractable matter in • Hot Water Extract (HWE) • Hot Ethanol Extract (HEE) • Cold Water Extract (CWE) • Cold Ethanol Extract (CEE) % Extractable mater = Weight of extract x 100 Weight of sample

  18. Ash Content : • 1.% Total ash = Ash Weight x 100 • Weight of sample • 2.% Acid-insoluble ash = Acid insoluble Ash Weight x 100 • Weight of sample • 3. % Water-soluble ash = • Total Ash Weight - water insoluble residue in total ash x 100 • Weight of sample

  19. TLC fingerprint profiles of W. volubilisand L. reticulata • Extract - methanol extract • Plant material - 4.0 g • Extracts were spotted on a silica gel plate and TLC fingerprints were developed using Dichloromethane: Ethyl acetate: Cyclohexane (40:1:10 v/v/v) • Vanillin-sulphuric acid reagent was used for colour development

  20. Statistical analysis • Data were analyzed by using Mann Whitney test and findings of p<0.05 was considered to indicate statistical significance • All data were presented as mean ± SEM • All the values were express as dry weight of the sample and they were performed in triplicate for accuracy

  21. Results Table 1 : Phytochemical classes of W. volubilis varities and L. reticulata

  22. Screening of phytochemical compounds of (a) cold and hot ethanol and water extracts of W. volubilis and L. reticulata revealed the presence of phenolic compounds, tannins, and steroids (b)cold and hot water extracts of W. volubilis and L. reticulata revealed the presence of saponins (c) cold and hot ethanol and water extracts of L. reticulata and hot extracts of W. volubilisrevealed the presence of coumarin (d)In addition, hot water extract of W. volubiliscontained flavanoids

  23. Table 2: Physicochemical parameters of Wattakaka volubilis and Leptadenia reticulata

  24. Following three physicochemical parameters of Jeewanti were significantly different from that of Tikta-anguna and Kiri-anguna 1. Hot and Cold Ethanol Extractable matter 2. Total ash Content 3. Acid-insoluble ash Content

  25. 3. TLC fingerprint profiles of Tikta-anguna, Kiri-anguna and Jeewanti 1 2 3 2µL 2µL 2µL 1 2 3 2µL 2µL 2µL Wave length – at 254 nm After spraying Vanillin -sulphuric acid • L. reticulata (Jeewanti ) • 2. W. volubilis(Kiri-anguna) • 3. W. volubilis (Tikta-anguna)

  26. Red – Tikta anguna (W. volubilis)Blue – Kiri anguna (W. volubilis)Green – Jeewanti (L. reticulata) TLC- densitogram fingerprint of Tikta-anguna, Kiri-anguna and Jeewanti, at 254 nm

  27. According to TLC fingerprints of Tikta-anguna, Kiri-anguna and Jeewanti, similar compounds were identified in three samples

  28. According to the results of this study, phytochemical parameters, physicochemical parameters and fingerprint profiles of Tikta-anguna and Kiri-anguna have very similar properties and they are similar to Jeewanti also

  29. conclusions • As this study reveals, Tikta-anguna, Kiri-anguna and Jeewanti have more similarities in terms of phytochemical parameters, physicochemical parameters and fingerprint profiles • Therefore, both Tikta-anguna and Kiri-anguna can be used as substitutes for Jeewanti in ayurvedic preparations

  30. According to traditional medicine, Kiri-anguna (Behet-anguna) is commonly used for medicinal preparations Further, Kiri-anguna (behet-anguna) can be considered as the “sweet variety” of W. volubilis and it has similar properties such as GUNA (Quality), RASA (Taste), VIPAK (Metabolism), VIRYA (Potency), PRABHAV (Impact) to Jeewanti • After considering all, we can conclude that kiri-anguna (behet-anguna) is much better to use as a substitute for Jeewanti
