“…The total percentage of the sesquiterpene group (85.4%) was more than 55 times higher than that of the monoterpene group (1.5%), indicating that the sesquiterpene was the dominant group in the essential oil of C. sichuanensis X. X. Chen. The result was comparable to those reported previously [7][8][9][10][11][12][13][14].…”

“…Recently, the chemical composition of the essential oil from leaves of Curcuma sp. have been reported [11,12]. ␣-Terpinyi acetate (8.4%), isoborneol (7%), dehydrocurdione (9%) and selina-4(15),7(11)-dien-S-one (9.4%) were determined as the major constituents of the essential oil in Curcuma zedoaria (Zingiberaceae) leaves [11].…”

“…and two cultivars of C. longa L. were analyzed by using GC. The leaf oils were characterized with the following major constituents-C. longa 'Roma': terpinolene (87.8%); C. longa 'Kasturi': myrcene (48.8%) and terpinolene (10.1%); C. caesia: 1,8-cineole (27%) and camphor (16.8%) [12]. Recently, a method with GC-MS and pressurized liquid extraction (PLE) was developed for the identification and determination/estimation of 11 sesquiterpenes including germactene D, curzerene in Ezhu which are derived from three species of Curcuma, namely C. phaeocaulis, C. wenyujing and C. kwangsiensis [13].…”

“…The primary identified components (above 5%) were the monoterpenes α-phellandrene (24.2-33.8%), terpinolene (16.5-22.6%), 1,8-cineole (14.7-16.3%), p-cymene (2.2-12.4%), and β-pinene (4.9-7.2%), whose sum ranges between 75 and 80%, when it is considered the total content of the constituents in the oil. These compounds were the same previously described in the literature (SHARMA et al, 1997;CHANE-MING et al, 2002;BEHURA and SRIVASTAVA, 2004;RAINA, SRIVASTAVA and SYAMSUNDAR, 2005). …”

“…The oil composition of C. longa, mainly from specimens grown in India, has been described in the literature. In the leaves oil, the principal constituents were monoterpenes, such as α-phellandrene, 1,8-cineole, pcymene, myrcene, terpinolene and camphor (SHARMA et al, 1997;CHANE-MING et al, 2002;BEHURA and SRIVASTAVA, 2004;RAINA, SRIVASTAVA and SYAMSUNDAR, 2005). In the rhizomes oil have predominated sesquiterpenes from tumerone, zingiberene and curcumene types (SHARMA et al, 1997;CHANE-MING et al, 2002;RAINA, SRIVASTAVA and SYAMSUNDAR, 2005;SINGH et al, 2010).…”

Avaliação da incidência de luz no plantio e produção de Curcuma longa, com base na análise de seus óleos essenciais de folhas e rizomas DOI 10.5935/2446-4775 ResumoCurcuma longa L. produz rizomas tradicionalmente vendidos no mercado internacional como "Turmeric". É um arbusto da Ásia, extensivamente cultivado na Índia, China, Japão e Indonésia. No Brasil, é conhecido como "Cúrcuma" ou "Açafrão" e utilizado principalmente em alimentos. O objetivo deste estudo foi avaliar o seu crescimento, dependendo da incidência de luz em cultivo experimental na região do Baixo Rio Amazonas, na cidade de Santarém, tendo por base a análise dos óleos essenciais de folhas e rizomas. As plantas obtidas no tratamento T1 (cultivo com 50% de sombreamento), após completar o ciclo de crescimento, mostraram melhor qualidade dos rizomas do que no tratamento T2 (cultivo a pleno sol). Estes resultados se refletiram na produtividade das plantas do tramento T1 (rizomas frescos = 14,86 ± 0,20 tons/ha), que foi maior do que no tratamento T2 (rizomas frescos = 3,97 ± 1,05 tons/ha). O rendimento em óleo foi 200% maior nas folhas jovens (3,19%) do que nas folhas adultas (1,17%). Nos rizomas, o rendimento em óleo foi maior no tratamento a pleno sol (3,00%) do que no tratamento com sombreamento de 50% (1,90%). Os principais constituintes do óleo das folhas jovens e adultas foram os monoterpenos α-felandreno (33,6% e 26,2%), terpinoleno (22,0% e 18,3%), 1,8-cineol (16,0% e 15,8%), p-cimeno (3,8% e 9,8%), and β-pineno (4,9% e 7,2%). Nos óleos dos rizomas foram as cetonas sesquiterpênicas turmerona (T1, 37,5%; T2, 38,5%), curlona (T1, 17,4%; T2, 30,4%), and ar-turmerona (T1, 9,3%; T2, 8,8%). Palavras AbstractCurcuma longa L. produces rhizomes traditionally sold on the international market as "Turmeric". It is a shrub from Asia, extensively cultivated in India, China, Japan and Indonesia. In Brazil, it is known as "Cúrcuma" or "Açafrão" and mainly used for food. The aim of this study was to evaluate the plant growth, depending on the incidence of light on an experimental cultivation in the region of Lower Amazon River, city of Santarém, based on the analysis of the essential oils from leaves and rhizomes. The plants obtained in treatment T1(growing 50% shading), after completing the growth cycle, have showed better quality of rhizomes than in the treatment T2 (full sun cultivation). The results are reflected in the productivity of plants of the T1 treatment (fresh rhizomes = 14.86 ± 0:20 tonnes/ha), which was higher than T2 treatment (fresh rhizomes = 3.97 ± 1.5 tonns/ha). The yield of oil was 200% higher in young leaves (3.19%) than in mature leaves (1.71%). In the rhizomes, the oil yield was greater in the treatment at full sunlight (T2, 3.00%) than in treatment with shading 50% (T1, 1.90%). The main constituents of the oil from young and mature leaves were the monoterpenes, α-phellandrene (33.6% and 26.2%), terpinolene (22.0% and 18.3%), 1,8-cineole (16.0% and 15.8%), pcymene (3.8% and 9.8%), and β-pinene (4.9% and 7.2%). In the oils of rhizomes we...

Involudispirones A( 1)a nd B( 2), ap air of cytotoxic sesterterpene stereoisomers containing a1 ,2-dioxadispiro[5.2.5.2]hexadecane ring, were isolated from the rhizomes of Stahlianthus involucratus.T heir structuresa nd absolute configurations weree stablished on the basis of spectroscopic dataa nd chemical conversion. Both 1 and 2 are cytotoxic.Zingiberaceae is al arge family of perennial herbaceous plants, members of which have attracted continuous phytochemical interestd ue to their culinary uses as well as their biological and pharmaceutical activities. [1] Our previous studies on different generao ft he Zingiberaceae family collected from South China have resulted in as eries of unique terpene derivatives, including sesquiterpene-chalcone conjugates, [2a] monoterpenechalcone conjugates, [2b] ak atsumadain dimer, [2c] and ar earranged labdane norditerpene. [2d] Stahlianthusi nvolucratus is at ropical Zingiberaceae plant and widely distributed in South China and Southeast Asia.I ts rhizomesh ave long been used in traditional medicinet ot reat inflammation, pain, and fever. [3] Previously,t hree unusualc adinaned imers involucratustones A-C were obtainedi no ur chemical investigation of the rhizomes of S. involucratus. [4] To further discover terpene derivatives, the extract of S. involucratus was subjected to am ore careful and intensive investigation, and resultedi nt he separation and identification of ap air of sesterterpene stereoisomers containing au nique 1,2-dioxadispiro[5.2.5.2]hexadecane ring system,n amed involudispirones A( 1)a nd B( 2,F igure 1), which are structurally differentf rom the previously reported cadinaned imers involucratustones A-C.
