Abstract

Background: “Shankhpushpi”, an important indigenous drug of Ayurveda, an ancient system of Indian medicine, improves memory power and intellect. It is used in many Ayurvedic formulations, either singly or in combination with other herbs, meant for sleeplessness, epilepsy, hallucinations and anxiety. At least three different plant species viz., Clitoria ternatea, Convolvulus pluricaulis and Evolvulus alsinoides are used as the source of this drug in the different parts of the country. Because of increased demand and high price, shankhpushpi is often adulterated in the trade by other related species. Therefore, a reliable authentication method is needed to facilitate differentiation/ identification of the genuine material from its adulterants. The present study was aimed at developing RAPD-based markers for identification of C. pluricaulis, E. alsinoides and C. ternatea, and analyzing the market samples of the drug to ascertain their authenticity. Materials and Methods: Fresh samples of source plants of shankhpushpi were collected from Ghaziabad and Delhi. The market samples were procured from the crude-drug markets of different geographical regions of India. The amplified polymorphic DNA (RAPD) technique was employed for characterization of genuine and market samples. Twenty-five 11-mer oligonucleotide primers were used to amplify the DNA isolated. Results: Out of 25 primers, only four (OPN-03, OPN-04, OPN-05 and OPN-06) yielded amplification products that produced clear and reproducible bands, which were used to characterize the market samples. RAPD profile of some market samples did not match with the authentic samples, indicating that these samples were either adulterated or spurious. Conclusions: The RAPD markers developed in this study may provide guidance for the authentication of plant materials traded as shankhpushpi.

Özet

Giriş: Çok eski bir Hint tıb sistemi olan Ayurveda’da önemli bir yerel ilaç olarak kullanılan “Shankhpushpi”, hafıza gücünü ve zekayı artırmaktadır. Uykusuzluk, sara, halüsinasyon ve anksiyete rahatsızlıkları için, tek başına veya başka otlarla kombinasyon halinde bir çok Ayurvedik formülde kullanılmaktadır. Ülkenin değişik bölgelerinde, en azından üç farklı bitki türü, yani Clitoria ternatea, Convolvulus pluricaulis ve Evolvulus alsinoides, bu ilacın kaynağı olarak kullanılmaktadır. Yüksek talep ve artan fiyatlar nedeniyle, shankhpushpi’ye diğer benzer türler karıştırılmaktadır. Bu nedenle, hakiki malzemeyi karışım için kullanılanlardan ayırt etmek için güvenilir bir doğrulama metoduna ihtiyaç vardır. Bu çalışma, C. pluricaulis, E. alsinoides ve C. ternatea’nın tanımlanması ve ilacın pazardan alınan örneklerinin hakikiliğini saptanması için RAPD tabanlı markörler geliştirmeyi amaçlamaktadır. Materyal ve Metot: Ghaziabad ve Delhi’den, Shankhpushpi’nin kaynak bitkilerinin taze örnekleri toplandı. Pazar örnekleri, Hindistan’ın farklı coğrafi bölgelerindeki ham-ilaç pazarlarından elde edildi. Hakiki ve pazar örneklerinin karakterizasyonu için RAPD tekniği kullanıldı. İzole edilen DNA’nın çoğaltılması için, yirmi beş 11-mer oligonükleotit primeri kullanıldı. Bulgular: 25 primerden sadece dört tanesi (OPN-03, OPN-04, OPN-05 ve OPN-06), pazar örneklerinin karakterizasyonu için kullanılan temiz ve tekrarlanabilir bantlar oluşturan çoğaltım ürünü verdi. Pazar ürünlerinden bazılarının RAPD profili, hakiki örneklerle eşleşmedi ve bu durum, bu örneklerin ya karışımlı veya sahte olduğunu göstermektedir. Sonuç: Bu çalışmada geliştirilen RAPD markörleri, shankhpushpi olarak satılan bitki materyallerinin doğrulanmasında yol gösterici olabilir.
