Research - Betulin / Betulinic Acid
Betulinic acid is a triterpene of natural origin isolated from various plants. It can be isolated from the methanolic extract of Quisqualis fructus [7], the dichloromethane-methanol extract of the twigs of Coussarea paniculata [8],the dichloromethane-methanol (1:1 v/v) extract of Argentinean legume Caesalpinia paraguariensis [9], the methanolic extract of the leaves of Vitex negundo [10], twigs of Ilex macropoda [11], the ethanolic extract of the roots of Anemone raddeana [12], leaves and wood of Doliocarpusschottianus [13], ethanolic extract of Tovomita krukovii [14],fruits of Chaenomeles lagenaria [15], methanol, hexane and ethyl acetate extracts of stem bark of Berlinia grandiflora[16], methanolic extract of the aerial parts of Vietnamese Orthosiphon stamineus [17], leaves of Eucalyptus camaldulensis [18], stem barks of Physocarpus intermedium[19] and Tetracentron sinense [20], chloroform extract of barks of Syncarpa glomulifera [21], methanolic extract of leaves of Combretum quadrangulare [22], methyl ethylketone extract of Tetracera boiviniana[23], dichloromethane extract of stem bark of Brazilian medicinal plant Zizyphusjoazeiro [24], ethanolic extract of the root barks of theTanzanian tree Uapaca nidida [25], Ipomea pescaprae [26],Ancistrocladus heyneanus [27], Diospyros leucomelas [28],and from the leaves of Syzrgium claviforum [5]

Abstract:
Betulinic acid is a naturally occurring pentacyclic triterpenoid and has been shown to exhibit a variety of biological activities including inhibition of human immunodeficiency virus (HIV), antibacterial,antimalarial, anti inflammatory, anthelmintic and antioxidant properties. This article reports a survey of the literature dealing with betulinic acid related biological properties that has appeared from the 1990’s to the beginning of 2003. A broad range of medical and pharmaceutical disciplines are covered, including a brief introduction about discovery, phytochemical aspects, organic synthesis, anti-HIV and cytotoxic mechanisms ofaction. Various structural modifications carried out and their biological and pharmacokinetic profiles are also incorporated.
