INTRODUCTION Mace aril contains more vitamin A, vitamin C, calcium, copper, iron and magnesium than nutmeg. Mace oil has been Myristica fragransis an evergreen tree belonging to the family used in dentistry for toothache relief and it is used a local Myrtaceae, indigenous to the Moluccas in Indonesia but it has massage to reduce muscular pain and rheumatic pain of joints. been successfully grown in other Asian countries. The species Indonesia and Grenada are the dominant producers and has been cultivated in many parts of the world for their nutmeg exporters of nutmeg and mace and India is also a leading and mace rich in valuable essential oils. Nutmeg contains about producer. However, Indian market and world markets have 10% essential oils chiefly composed of terpene hydrocarbons been flooded with adulterants of nutmeg and mace. The Indian (sabinene and pinene), myrcene, phyllandrene, camphene, mace is adulterated with the mace of Myristica malabarica, limonene, terpinene, pcymene and other terpnene derivatives commonly called Bombay mace.

  • Reconstructing the Basal Angiosperm Phylogeny: Evaluating Information Content of Mitochondrial Genes
    55 (4) • November 2006: 837–856 Qiu & al. • Basal angiosperm phylogeny Reconstructing the basal angiosperm phylogeny: evaluating information content of mitochondrial genes Yin-Long Qiu1, Libo Li, Tory A. Hendry, Ruiqi Li, David W. Taylor, Michael J. Issa, Alexander J. Ronen, Mona L. Vekaria & Adam M. White 1Department of Ecology & Evolutionary Biology, The University Herbarium, University of Michigan, Ann Arbor, Michigan 48109-1048, U.S.A. [email protected] (author for correspondence). Three mitochondrial (atp1, matR, nad5), four chloroplast (atpB, matK, rbcL, rpoC2), and one nuclear (18S) genes from 162 seed plants, representing all major lineages of gymnosperms and angiosperms, were analyzed together in a supermatrix or in various partitions using likelihood and parsimony methods. The results show that Amborella + Nymphaeales together constitute the first diverging lineage of angiosperms, and that the topology of Amborella alone being sister to all other angiosperms likely represents a local long branch attrac- tion artifact. The monophyly of magnoliids, as well as sister relationships between Magnoliales and Laurales, and between Canellales and Piperales, are all strongly supported. The sister relationship to eudicots of Ceratophyllum is not strongly supported by this study; instead a placement of the genus with Chloranthaceae receives moderate support in the mitochondrial gene analyses. Relationships among magnoliids, monocots, and eudicots remain unresolved. Direct comparisons of analytic results from several data partitions with or without RNA editing sites show that in multigene analyses, RNA editing has no effect on well supported rela- tionships, but minor effect on weakly supported ones. Finally, comparisons of results from separate analyses of mitochondrial and chloroplast genes demonstrate that mitochondrial genes, with overall slower rates of sub- stitution than chloroplast genes, are informative phylogenetic markers, and are particularly suitable for resolv- ing deep relationships.

  • First Records of Stranded Nutnegs Myristica Fragrans Houttuyn, 1774 (Magnoliales: Myristicaceae) on the Irish Coast and a Review of North Atlantic Records
    Bulletin of the Irish Biogeographical Society Number 44 (2020) FIRST RECORDS OF STRANDED NUTNEGS MYRISTICA FRAGRANS HOUTTUYN, 1774 (MAGNOLIALES: MYRISTICACEAE) ON THE IRISH COAST AND A REVIEW OF NORTH ATLANTIC RECORDS *Declan T. G. Quigley1, Liam MacNamara2 and Paul A. Gainey3 1Sea Fisheries Protection Authority, Eastern Region, West Pier, Howth, Co. Dublin, Ireland. 2Derreen, Craggagh, Fanore, Co. Clare, Ireland. 3Polwithen Road, Penryn, Cornwall TR10 8QT, U.K. *Corresponding author e-mail: <[email protected]> Abstract Between July and October 2019, LMN discovered a total of 23 nutmegs Myristica fragrans Houttuyn, 1774 stranded at various locations along the shoreline of County Clare, on the Atlantic coast of western Ireland. The specimens represent the first records of stranded M. fragrans seeds from Irish waters. The occurrence and potential provenance of stranded nutmegs on Irish and North Atlantic maritime shores are reviewed. Flotation experiments suggest that some stranded nutmegs may represent true peregrine trans-Atlantic drifters while others may have been locally discarded. Key words: Nutmeg, Myristica fragrans, stranded nutmegs, Irish waters and North Atlantic. Introduction The pantropical family Myristicaceae consists of c.21 genera and c.520 species of woody trees, shrubs and, occasionally lianas (Cristenhusz and Byng, 2016; Santamari-Aguilar et al., 2019). Myristica is a genus of trees native to tropical Asia and the Western Pacific. Although at least 446 species and sub-species of Myristica have been described (Anon., 2020a), the identification of Myristica species based on traditional morphological criteria has always proven difficult, and so far, even DNA barcoding techniques based on rbcL and matK genes have generally failed to satisfactorily differentiate between species (Tallei and Kolondam, 2015; Nanlohy et al., 2017; Swetha et al., 2019).

Over one and a half million practitioners of the Indian system of medicine use medicinal plants in preventive and curative applications. In recent years, secondary plant metabolites (phytochemicals), previously with unknown pharmacological activities, have been extensively investigated as [1] source of medicinal agents . The World Health Organization (WHO) has given guidelines to the member states to ensure about genuine use of plants and their parts before their use for human health [2].

Kathirgamattaiyah Director Department of Minor Export Crops AUG - 9?09 ABSTRACT Responses to in vitro culture of explants taken from shoot tips from juvenile and adult shoot tips, axillary buds, leaves, ovules and embryo or endosperm of clonal selections of nutmeg and clove were tested. Complete plant regeneration with higher rate of multiplication was achieved with shoot tip culture of juvenile plants of both species. Partial success -was achieved in axillary bud culture in clonal trees of both species. Shoot tip explants taken from juvenile plants of clove and nutmeg were established successfully in Anderson's culture medium supplemented with 2.0 mg/I BA with or without 0.1-0.2 mg/l NAA. Multiplication of juvenile nutmeg (4-5) and clove (6) was obtained within an eight week period in Anderson's solid medium supplemented with 2.0 mg/i BA. Agitated liquid medium with the same nutrient composition gave the highest rate of multiplication (6) with greater shoot growth of nutmeg, whereas, for clove liquid media were found to be not suitable. The best subculture period for nutmeg cultures was about four weeks and the most suitable portion of the shoot to achieve highest multiplication was 0.5-2.5 cm from the apex.

Available Online: 1st March, 2017 ABSTRACT Objective: Myristica fragrans Houtt commonly used as traditional medicine for alleviating of various disorders. The purpose of our study was to map out the in vitro antioxidant property and in vivo anti-hyperglycemic and analgesic effect of the methanolic extract of Myristica fragrans Houtt. (Seed and mace) (Myristicaceae) on Swiss albino mice. Methods: The processed powder of Myristica fragrans Houtt (seed and mace) were subjected to methanolic extraction by soxhlet filtration methods, and the desiccated extract was used for screening of antioxidant by DPPH free radical scavenging assessment as well as total phenolic content by using folin-ciocalteu reagent.Anti-hyperglycemic effect and analgesic action tested through alloxan induced antidiabetics test and acetic acid-tempted writhing test on mice. Results: In DPPH free radical scavenging assessment, free radicals neutralization expressed as % of inhibition 49.69±0.06% also by IC50 values as 68.43 µg/ml surmise middle level of antioxidant property. The total phenolic content expressed as 186.25 mg/g equivalent of gallic acid indicates, active phenolic content.
