Zenkevichb) National Institute of Standards and Technology, Gaithersburg, Maryland 20899, USA (Received 1 August 2011; accepted 27 September 2011; published online 29 November 2011) Gas chromatographic retention indices were evaluated for 505 frequently reported plant essential oil components using a large retention index database. Retention data are presented for three types of commonly used stationary phases: dimethyl silicone (nonpolar), dimethyl sili- cone with 5% phenyl groups (slightly polar), and polyethylene glycol (polar) stationary phases. The evaluations are based on the treatment of multiple measurements with the number of data records ranging from about 5 to 800 per compound. Data analysis was limited to temperature programmed conditions. The data reported include the average and median values of retention index with standard deviations and confidence intervals.

    Cherimoya and Guanabana in the Archaeological Record of Peru

    Journal of Ethnobiology 17(2):235-248 Winter 1997 CHERIMOYA AND GUANABANA IN THE ARCHAEOLOGICAL RECORD OF PERU THOMAS POZORSKI AND SHELIA POZORSKI Department of Psychology and Anthropology University of Texas-Pan American Edinburg, TX 78539 ABSTRACT.-Most researchers commonly assume that both cherimoya (Annona cherimolia) and guanabana (Annona muricata) have long been a part of the prehistoric record of ancient Peru. However, archaeological and ethnohistoric research in the past 25years strongly indicates that cherimoya was not introduced into Peru until ca. A.D. 1630 and that guanabana is only present after ca. A.D. 1000and is mainly associated with sites of the Chimu culture. RESUMEN.-La mayorfa de los investigadores suponen que tanto la chirimoya (Annona cherimola)como la guanabana (Annona muricata) han sido parte del registro prehist6rico del antiguo Peru por largo tiempo . Sin embargo, las in vestigaciones arqueol6gicas y etnohist6ricas de los ultimos veinticinco afios indican fuertemente que la chirimoya no fue introducida al Peru sino hasta 1630 D.C., Y que la guanabana esta presente s610 despues de aproximadamente 1000 D.C., Y esta asociada principalmente con sitios de la cultura chirmi. RESUME.- La plupart des chercheurs supposent couramment qu'une espece de pomme cannelle (Annonacherimolia)et le corossol (Annona muricata) ont faitpartie, pendant une longue periode, de l'inventaire prehistorique du Perou. Toutefois, les recherches archeologiques et ethnohistoriques des vingt-cinq dern ieres annees indiquent fortement que la pomme cannelle A. cherimolia ne fut introduite au Perou qu'aux environs de 1630 apr.

    PEER-REVIEWED ARTICLE bioresources.com Chemical Composition and Antimicrobial and DPPH Scavenging Activity of Essential Oil of Toona sinensis (A. Juss.) Roem from China Congjin Chen,a,c,* Zhangfa Tong,a Dankui Liao,a Yue Li,a Guoen Yang,b and Mingfei Li c The chemical components of essential oil of Toona sinensis leaf blades and their petioles from China were extracted by simultaneous distillation solvent extraction (SDE) and were analyzed by GC-MS. The antimicrobial and DPPH scavenging activity of the essential oil were evaluated. The results showed that there were differences in chemical compositions and content among essential oils extracted from T. sinensis in different parts and different geographical areas in China, but the main components of essential oils were sesquiterpene and sesquiterpene oxygenated compounds, accounting for 90.1% (No. 1), 92.6% (No. 2), and 80.9% (No. 3) of the relative mass fraction, respectively. T. sinensis essential oil exhibited noticeable growth inhibitory activity against the tested microorganisms. The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of different essential oils against microorganisms were different. For all essential oil samples, MIC and MBC against Escherichia coli and Bacillus subtilis were less than 25 μg·mL−1, MIC and MBC against Penicillium citrinum were 200 and 400 μg·mL−1, respectively, and MIC and MBC against Colletotrichum gloeosporioides were 50 and 200 −1 μg·mL , respectively. The IM50 of DPPH scavenging for T. sinensis essential oil was less than 0.3 g DPPH per g essential oil. The results indicated that T. sinensis essential oil may be a useful natural antiseptic source from forest products.
  • The Cherimoya in Argentina

    The Cherimoya in Argentina

    California Avocado Society 1942 Yearbook 26: 122-123 The Cherimoya in Argentina Ing. Hernando de Irmay (Translation) The cultivation of the cherimoya in this country is very old. According to data which I have been able to gather, the cherimoyas were brought here from Bolivia, possibly from the region of Tarija or Santa Cruz de la Sierra. There is no record that named varieties of cherimoyas were imported from the exterior, and the existing orchards are almost all of seedlings grown from seeds of the better fruits. In the regions of Salta, Tucuman, and Jujuy, where about 95% of the orchards are located, the method of budding that has been and is still in use is the "umbonata como pie" (bent like a foot, or bent at right angle) which method, up to the present time, has given the best results. At the present time we have in Salta a selection of the best varieties of cherimoya— varieties which have been chosen for their excellent fruits, good production, and greatest resistance to frost. This selection consists of nine varieties, and the distribution of these varieties has already begun. The difficulties which we have in extending on a larger scale the cultivation of the cherimoya consist of the small production of the trees under cultivation and of the poor resistance to occasional freezes in the areas being cultivated. ROLINIA ROOT-STOCK INCREASES HARDINESS In regard to increasing the resistance to frost, the writer started years ago to experiment with the Rolinia emarginata (Rolinia is a plant belonging to the botanical family "Annonaceae") a species which grows wild in Misiones, Formosa, and other areas bordering Paraguay, where it has resisted temperatures as low as 10° centigrade below freezing, on certain occasions, without injury.

    Comparative Analysis of Volatile Terpenes and Terpenoids in the Leaves of Pinus Species—A Potentially Abundant Renewable Resource

    molecules Article Comparative Analysis of Volatile Terpenes and Terpenoids in the Leaves of Pinus Species—A Potentially Abundant Renewable Resource Wensu Ji 1 and Xiaoyue Ji 2,* 1 Ordnance Non-Commissioned Officers School, Army Engineering University of PLA, Wuhan 430075, China; [email protected] 2 Advanced Analysis & Testing Center, Nanjing Forestry University, Nanjing 210037, China * Correspondence: [email protected] Abstract: Pinaceae plants are widely distributed in the world, and the resources of pine leaves are abundant. In the extensive literature concerning Pinus species, there is much data on the composition and the content of essential oil of leaves. Still, a detailed comparative analysis of volatile terpenes and terpenoids between different species is missing. In this paper, headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry was used to determine the volatile terpenes and terpenoids of typical Pinus species in China. A total of 46 volatile terpenes and terpenoids were identified, and 12 common compounds were found, which exhibited a great diversity in the leaves of Pinus species. According to the structures and properties of the compounds, all those compounds can be classified into four categories, namely monoterpenes, oxygenated terpenes, terpene esters, and sesquiterpenes. The results of principal component analysis and cluster analysis showed that the leaves of the six Pinus species could be divided into two groups. The species and contents of volatile terpenes and terpenoids in the leaves were quite different. The results not only provide a reference Citation: Ji, W.; Ji, X. Comparative for the utilization of pine leaves resource, but also bring a broader vision on the biodiversity.
