The family Lamiaceae is usually a substantial loved ones of order Lamiales [1]. It consists of about 170 genera and 300 species of worldwide distribution, expanding under terrific variety of soils and climates but much more abundant in Mediterranean and mountainous region [2]. Various genera on the family Lamiaceae include biologically active compounds [3]. Teucrium is one of the critical genera of this household [4]. The genus Teucrium comprises primarily herbaceous plants. It consists of about 7,000 species in temperate regions, only four species of which are reported in Pakistan, namely, Teucrium stocksianum, Teucrium scordium, Teucrium royleanum, and Teucrium quadrifarium [5]. Quite a few biological activitieshave been attributed towards the genus Teucrium. Some of the species have been made use of as medicinal plants given that time immemorial and are nevertheless getting used in folk medicine as antispasmodics, tonics, antipyretics, and antiseptics [6]. The literature survey reveals that the terpenoids in these plants have also shown insect antifeedant activity [6?]. These medicinal properties prompted us to carry out phytochemical investigation on T. royleanum incontinuation to our ongoing research on this species [9?11]. Our existing study has led for the isolation of 1 new royleanumoate, abenzene ester 1. In addition to the new compound 1, some identified compounds three,4-dihydroxymethyl benzoate two and oleanolic acid three happen to be isolated for the very first time from this species (see Figures 2, 3, and four).2. Material and Methods2.1. Plant Components. The aerial components of T. royleanum have been collected from Swat (Pakistan) in June 2003 and identified by Professor Dr. Abdul Rashid, Plant Taxonomist, Department of Botany, University of Peshawar, Peshawar, Pakistan, exactly where a voucher specimen (number Shabir 2651979 (PUP)) is deposited. two.two. Solutions for Purification. The powdered air-dried aerial parts of T. royleanum (10 kg) were soaked in MeOH (three ?45 L) at space temperature for about 24 hours. The combined methanolic extract was then concentrated by means of rotavapour toTable 1: 1 H-NMR and 13 C-NMR (C5 D5 N, 400 MHz, C5 D5 N, one hundred MHz), chemical shifts, and multiplicities of (1).
