ABSTRACT medicinal activity of indigenous plant species in Medicinal plants are a reservoir of biologically Uzbekistan. active compounds with therapeutic properties that over time have been discovered and used by diverse INTRODUCTION groups of people for treatment of various ailments. The idea that plants are a reservoir of biologically In this regard, Uzbekistan has an excellent historic active compounds with therapeutic properties has been research base of herbal medicines with about 70% of well established, and since ancient time they have been Uzbek households using medicinal plants to meet used worldwide for the treatment of various ailments, their health needs for several centuries. The flora of including asthma, gastro-intestinal problems, skin Uzbekistan includes more than 4500 species of disorders, respiratory and urinary complications, and vascular plants and over 600 of these plants are used hepatic and cardiovascular disease (Cousins and in traditional or conventional medicines, significantly Huffman, 2002; Tian et al., 2014). The interest on surpassing other areas by the absolute number of demand for more plant derived drugs, which sometimes endemics and the percentage of endemism. The are considered as safe when compared to synthetic drugs, plants are a reservoir of secondary metabolites, is increasing rapidly. suitable for use in pharmacological studies with a The medicinal value of these plants lies in chemical high possibility of observing biologically active substances that produce a positive physiological action on constituents. The present review provides an up-to- the human body (Edeoga et al., 2005), and since plants date a report on the phytochemicals and synthesize an extremely diverse range of chemical pharmacological activity of the medicinal plants compounds, they represent a great potential for the widely used in Uzbekistan. As a country, Uzbekistan discovery and development of new pharmaceuticals appears to be a source of novel herbal drugs that have (McChesney et al., 2007). not yet been fully evaluated. We trust the present While numerous studies have validated the report will be useful for further investigations on the traditional use of medicinal plants by investigating the 59 Journal of Medicinally Active Plants Vol. 5, Iss. 2 [2016], phytochemicals present in active extracts (Van-Wyk and P. tschimganica, and Rheum maximowiczii contain Wink, 2005; Palombo, 2006), many plants have not previously unknown antioxidants. Some of these yet been scientifically studied to provide reports on their antioxidants seem to have a unique mechanism of action. phytochemical constituents and their potential medicinal Several pharmacological activities of medicinal plants applications. and their constituents, such as antimicrobial Traditional medicine of Central Asia is not widely (Mamadalieva et al., 2008), anti-inflammatory, and known, and only in recent times has the scientific antioxidative (Mulaudzi et al., 2013), cytotoxic community focused attention on these plants and the (Manosroi et al., 2014), along with anabolic activity and medicinal uses developed in Uzbekistan.

The traditional use of et al., 2010). medicinal plants in Uzbekistan is widespread and over Early studies on native Uzbekistan plants detected 70% of Uzbek households have used medicinal plants for anthocyanins and coumarins (Pulatova, 1969) and centuries, coming from a variety of plant families and essential oils (Nuriddinov et al., 1997) in Perovskia suggesting that pharmacological studies would have a scrophularifolia Bunge (Lamiaceae). Several alkaloids, high probability of detecting active compounds. The iridoids, and secoiridoid glycosides, and flavonoid majority of these plants, however, grow under harsh glycosides of Gentiana olivieri (Gentianaceae) have environmental conditions that limited access to plant been reported (Rakhmatullaev et al., 1969; Ersöz et al., material. 1991). Another native plant from Uzbekistan, Investigative studies have demonstrated that Helichrysum sp. (Asteraceae), contains flavonoids, many of the endemic plants of Uzbekistan contain phloroglucinol derivatives, and diterpenes (Suzgec et al., flavonoids, alkaloids, tannins, saponins, phenolic 2005). Su et al. (2000) identified several novel compounds, coumarins, terpenes and ecdysteroids that compounds from the roots of Ferula pallida (Apiaceae), could be potential sources for several effective drugs a native plant of Uzbekistan that contains sesquiter- (Tulyaganov and Kozimova, 2005; Gapparov et al., penes, phenylpropanoid derivatives, pallidones, and 2007; Mamadalieva et al., 2011; Gapparov and sesquiterpene chromone derivatives.
