Subject:
sesquiterpenoids; plant extracts; Curcuma; spectral analysis; chemical structure
Abstract:
... Two new cadinane sesquiterpenes (1 and 2) were isolated from Curcuma parviflora, and their structures were elucidated by spectroscopic data. Compound 1, 4α-acetoxycadina-2,9-diene-1,8-dione, possesses two conjugated enone chromophores, while compound 2, 1α,3α,4β-trihydroxy-9-cadinen-8-one, has an enone moiety with three hydroxy groups. Isolation of these cadinane monomers may reasonably suggest th ...

Abstract:
... Sugarcane (Saccharum spp.) is an economical crop in the tropical and subtropical countries. However, because of global climate change, flooding has become problematic, particularly during the rainy season, in Thailand. We investigated the effects of floods on three commercial sugarcane cultivars, namely NiF8, U-thong 6 (UT6), and U-thong 9 (UT9), as well as Erianthus spp. Growth was assessed using ...

Abstract:
... Seagrass meadows have great capacity to sequester and store organic carbon (OC) in sediments for the long term and have been considered as a carbon dioxide sink for national greenhouse gas inventories in the Intergovernmental Panel on Climate Change Guidelines. Therefore, there is an urgent need to determine a reliable, well‐constrained estimate of the baseline long‐term OC sequestration (burial) ...

Polymorphisms in the nucleotide sequences of the mitochondrial genes of this species were examined, and combined into seven haplotypes among the test insect specimens originating from Japan, Thailand, and Canada. These results suggested the potential for geog ...
