Prunus armeniaca L., apricot, is a member of family Rosaceae bears deciduous tree [1]. Still its origin is unclear among the researchers. In olden times it was known in America, then started to cultivate [2]. It is assumed that it may have originated in Northeastern China close to the Russian border. According to Morikian ES [3] it was known to Armenians which is supported by the discovery of i...

The volatile oil obtained by hydrodistillation of the petals of Rosa damascena Mill. (Rosaceae) was analyzed by gas chromatography and gas chromatography/mass spectrometry (GC/MS). The yield of the oil was 0.12 % (v/w). Fifty compounds representing 99.06 % of the oil were characterized. The volatile oil was found rich in sesquiterpenes and aliphatic components, consisting of two monoterpenic es...

Two new species of Amblypalpus (Acari: Trombidiformes: Tenuipalpidae) are described from Iran: Amblypalpus iraniensis sp. nov., from Wild Almond, Amygdalus scoparia (Rosaceae), and Amblypalpus thymus sp. nov., from Common Thyme, Thymus vulgaris (Lamiaceae). The new species are classified tentatively in Amblypalpus. The species Priscapalpus thomissus Meyer, 1979 is transferred to Amblypalpus and...

A novel cucurbitacin glycoside has been isolated from aerial parts of Kageneckia oblonga R. et P. and shown to be 3beta-(beta-D-glucosyloxy)-16alpha,23alpha-epoxycuc urbita-5,24-dien-11-one. The structure was established by usual spectroscopic and two-dimensional (2D) NMR techniques. This compound has found to be nontoxic when tested in-vivo cell culture assays. In previous investigations we re...

Two new triterpenoids, 2α,3β-dihydroxyolean-11,13(18)-dien-19β,28-olide (1) and 3β,5β-dihydroxyglutinol (2), together with eight known compounds (3-10) were isolated from the roots of Rhaphiolepis indica var. tashiroi (Rosaceae). The structures of 1-10 were determined by spectroscopic techniques. Among these isolates, 2α,3β-dihydroxyolean-13(18)-en-28-oic acid (9) exhibited inhibitory effect on...

An infestation of Cicadatra persica KirKaldy (Hemiptera: Cicadidae) on apple trees, Malus domestica Borkhausen (Rosales: Rosaceae), was reported for the first time in the apple fruit orchards of Erneh, Syria. Nymphs, adults, exuvia, and exit holes in the soil were observed. The species was identified as C. persica based on morphological characters. Some biological observations and an acoustic a...

Sorbus commixta Hedl. (Rosaceae) has been traditionally used in oriental countries for the treatment of asthma and other bronchial disorders. In this study, a chalcone glycoside was isolated from the ethyl acetate extract of the fruits of this plant. The compound was identified as neosakuranin based on the spectroscopic analysis and comparison with literature data. This is the first report of i...
