Essential oil of Curcuma amada Roxb. from Northeastern India
No full textThe oil, which was obtained by the steam distn. of the fresh rhizomes of C. amada (Zingiberaceae) growing in the plain districts of Northeastern India, was investigated by GC/MS. Nine components (97.4%) were identified. Myrcene was the major (88.6%) component. [on SciFinder (R)
Characterization of Volatile Organic Compounds in Mango Ginger (Curcuma amada Roxb.) from Myanmar
No full textCurcuma amada Roxb. (Zingiberaceae), commonly known as mango ginger because its rhizome and foliar parts have a similar aroma to mango. The rhizome has been widely used in food industries and alternative medicines to treat a variety of internal diseases such as cough, bronchitis, indigestion, colic, loss of appetite, hiccups, and constipation. The composition of the volatile constituents in a fresh rhizome of C. amada is not reported in detail. The present study aimed to screen and characterize the composition of volatile organic compound (VOC) in a fresh rhizome of three C. amada (ZO45, ZO89, and ZO114) and one C. longa (ZO138) accessions originated from Myanmar. The analysis was carried out by means of headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-time-of-flight-mass spectrometry (GC-TOF-MS). As a result, 122 VOCs were tentatively identified from the extracted 373 mass spectra. The following compounds were the ten most highly abundant and broadly present ones: ar-turmerone, α-zingiberene, α-santalene, (E)-γ-atlantone, cuparene, β-bisabolene, teresantalol, β-sesquiphellandrene, trans-α-bergamotene, γ-curcumene. The intensity of ar-turmerone, the sesquiterpene which is mainly characterized in C. longa essential oil (up to 15.5–27.5%), was significantly higher in C. amada accession ZO89 (15.707 ± 5.78a) compared to C. longa accession ZO138 (0.300 ± 0.08b). Cis-α-bergamotene was not detected in two C. amada accessions ZO45 and ZO89. The study revealed between-species variation regarding identified VOCs in the fresh rhizome of C. amada and C. longa
Volatile aroma components of Curcuma amada Roxb.
No full textThe aroma concentrate of fresh rhizomes of Curcuma amada Roxb. ['mango ginger', used as a spice in pickling, chutneys, etc.] was prepared by an efficient simultaneous steam distillation/solvent extraction. Qualitative analysis of these volatile aroma components was performed by GC-MS aided by a computer library search. This led to the identification of 61 unreported compounds out of 68 compounds for which mass spectra were recorded. Identification of the components was confirmed by their Kovats retention indices. The aroma concentrate of mango ginger was comprised of a mixture of character impact compounds by both raw mango and turmeric
Comparative study of phytochemicals and bioactivities of the leaf extracts of Curcuma amada and Curcuma karnatakensis
No full textCurcuma species are known for their medicinal properties, and it is essential to evaluate under-explored species for their phytocomposition and their practical applications. The present work evaluated the phytochemical, antioxidant, antimitotic, and antiproliferative properties of aqueous methanolic extract from leaves of Curcuma amada and Curcuma karnatakensis. Quantitative phytochemical assays revealed higher amounts of phenols (11.00 ± 0.29 mg GAE / g DW), flavonoids (8.80 ± 0.03 mg QE / g DW), tannins (3.30 ± 0.02 mg CE / g DW) and saponins (53.23 ± 0.02 mg DE / g DW) in C.amada extracts compared to C. karnatakensis. Aqueous methanolic extract of C. amada exhibited higher radical scavenging activity for DPPH (IC50= 127.70 ± 4.05 μg / mL), Ferrous ion chelation (IC50= 287.83 ± 6.38 μg / mL) and CUPRAC antioxidant potential value of 6.33 ± 0.06 mg Trolox equivalent (TE)/g DW. C. karnatakensis exhibited higher ABTS radical scavenging activity with an IC50 value of 96.97 ± 1.58 μg / mL. Further, GC-MS analysis of extracts identified several sesquiterpenoids in both species having significant biological activities. The two extracts exhibited mild antimitotic and antiproliferative properties against Allium root cells and yeast cells. C. amada leaf extract showed higher anti-inflammatory properties than C. karnatakensis. This is the first comprehensive report on leaf phytocomposition, which could be exploited for pharmacological utilization
Ensoñando la casa y la ciudad: la construcción femenina y espacial en la novela El álbum de Amada Díaz
No full textThis work analyses the novel �El album de Amada Díaz� by Ricardo Orozco, with the goal to present from a different perspective, the eyes of its protagonist, Amada Díaz, Porfirio�s daughter, the two most relevant historical periods in Mexico: �La Revolución� and �El Porfiriato�. In other words, the novel does not seek only unification and re-signification of both periods, instead, the author manages a �reconstruction� of Mexico City, which was �silenced� by the absolutist voice of the patriarchal groups.Este trabajo estudia la novela de Ricardo Orozco El álbum de Amada Díaz con el objetivo de presentar de una manera diferente, a través de la mirada de su protagonista, Amada Díaz, hija de Porfirio Díaz, los dos períodos históricos de mayor trascendencia en México: la Revolución y el Porfiriato. Es decir, la novela no solamente busca la unificación y re-significación de ambos períodos, sino que además el autor logra la �reconstrucción� de una ciudad de México �acallada� por la voz absolutista de los grupos patriarcale

Isolation and characterization of antioxidant and antibacterial compound from mango ginger (Curcuma amada Roxb.) rhizome
No full textThe chloroform extract of mango ginger (Curcuma amada Roxb.) rhizome was subjected to antioxidant activity-guided purification by repeated silica gel column chromatography to obtain a pure antioxidant compound. The structure was deduced by analyzing UV, IR, liquid chromatography–mass spectrometry (LC–MS) and two-dimensional heteronuclear multiple quantum coherence transfer spectroscopy (2D-HMQCT) NMR spectral data, and named it as “Amadannulen”, a novel compound. It exhibited DPPH radical scavenging activity, super oxide radical scavenging activity, lipid peroxidation inhibitory activity and metal chelating activity. Amadannulen also showed antibacterial activity against both Gram-positive and Gram-negative bacteria tested. It also exhibited bactericidal activity against M. luteus, B. cereus and B. subtilis

Trauma, Cura, Comunidade: As Faces de Cristo em Amada, de Toni Morrison
No full textThis article aims to analyze Beloved, by Toni Morrison, focusing especially on the intertextual biblical elements about Jesus and his ministry. Against the backdrop of black liberation theology, this article argues that in Beloved Morrison imbues her characters with Christological features to interrogate Eurocentric for-ms of doing theology, namely, a form of theology which pays little attention to the goals, needs and suffering of black communities victims of racism and oppres-sion. In the novel, Morrison privileges a form of spirituality that embraces princi-ples, symbols and elements of the Christian faith, but places them in the context of African American culture and spirituality. The result is a contextual theology which valorizes local sensitivities about the human’s relation with Alterity.Este artigo tem como objetivo fazer uma análise de Amada, de Toni Morrison, com foco especial nos elementos intertextuais bíblicos acerca de Jesus e seu ministério. Usando como pano de fundo as reflexões da teologia da libertação negra, argumenta que em Amada Morrison investe seus personagens de características cristológicas com o propósito principal de interrogar formas eurocêntricas de se fazer teologia, ou seja, um teologizar insensível aos anseios, necessidades e sofrimentos das comunidades negras afetadas pelo racismo e opressão fruto da supremacia branca. No romance, Morrison privilegia uma reflexão que abraça princípios, símbolos e elementos da fé cristã, mas que os coloca no contexto da espiritualidade e cultura das comunidades afrodescendentes. Assim, surge um teologizar mais contextual, que valoriza formas e expressões locais de se pensar a relação com a Alteridade.
