The Importance of Extraction, Purification and Spectroscopic Analysis Techniques in the Discovery of Bioactive Natural Products

Abstract

Since ancient times, natural resources like plants, bacteria, fungi, and marine organisms have been utilized to develop new drugs. Natural products continue to be compounds of interest today as drug candidates due to their functional group diversity, molecular asymmetry and complex structure. However, the concentration of pharmacologically active substances found in natural sources are relatively low. Furthermore, the time-intensive extraction and purification process also limits the discovery of drugs from natural resources. Therefore, the development of selective and efficient experimental procedures for the extraction and isolation of bioactive metabolites still remains essential. This review aims to comprehensively summarize both conventional and modern extraction methods used to obtain biologically active natural products, various chromatography techniques applied in their purification and isolation, and the spectroscopic techniques necessary for elucidating their chemical structures.

Biyoaktif Doğal Ürünlerin Keşfinde Ekstraksiyon, Saflaştırma ve Spektroskopik Analiz Tekniklerinin Önemi

Abstract

Eski çağlardan beri bitkiler, bakteriler, mantarlar ve deniz organizmaları gibi doğal kaynaklar yeni ilaçlar geliştirmek için kullanılmıştır. Doğal ürünler, fonksiyonel grup çeşitliliği, moleküler asimetri ve karmaşık yapıları nedeniyle günümüzde de ilaç adayı olarak ilgi çeken bileşikler olmaya devam etmektedir. Ancak, doğal kaynaklarda bulunan farmakolojik olarak aktif maddelerin konsantrasyonu nispeten düşüktür. Ayrıca, zaman alıcı ekstraksiyon ve saflaştırma süreci de doğal kaynaklardan ilaç keşfini kısıtlamaktadır. Bu nedenle, biyoaktif metabolitlerin ekstraksiyonu ve izolasyonu için seçici ve etkili deneysel prosedürlerin geliştirilmesi hâlâ önemini korumaktadır. Bu derleme, biyolojik olarak aktif doğal ürünler elde etmek için kullanılan hem geleneksel hem de modern ekstraksiyon yöntemlerini, saflaştırma ve izolasyonlarında uygulanan çeşitli kromatografi tekniklerini ve kimyasal yapılarının aydınlatılması için gerekli spektroskopik teknikleri kapsamlı bir şekilde özetlemeyi amaçlamaktadır.
