The Saccharum sensu stricto (s.s) genus consists of three recognised species: S. spontaneum, S. officinarum and S. robustum, and three subspecies: S. sinense, S. barberi and S. edule. Currently, limited knowledge is available about the precise descent of these species from one another. Modern sugarcane arose through the ‘Nobilization’ process, and it is believed that S. officinarum and S. spont...

Commercial sugarcane hybrid cultivars currently in production are high-yielding, disease-resistant, millable canes and are the result of years of breeding work. In Hawaii, these commercial hybrids are quite distinct from many Saccharum officinarum canes still in existence that were brought to the islands and cultivated by the native Polynesians. The actual genetic relationships among the native...

In the present study, the terminal-restriction fragment length polymorphism (T-RFLP) technique, combined with the use of a clone library, was applied to assess the baseline diversity of fungal endophyte communities associated with rhizomes of Alpinia officinarum Hance, a medicinal plant with a long history of use. A total of 46 distinct T-RFLP fragment peaks were detected using HhaI or MspI mon...

Alpinia officinarum has been confirmed to possess bioactivities against some pests. In this work, a sample was obtained from A. officinarum rhizomes by supercritical fluid CO₂ extraction (SFE). According to GC-MS analysis, the main chemical components for SFE-sample included benzylacetone (26.77%), 1,7-diphenyl-5-hydroxy-3-heptanone (17.78%), guaiacylacetone (10.03%) and benzenepropanal (7.42%)...

In the present study, ultra-performance liquid chromatography (UPLC) coupled to electrospray ionization (ESI(+)) tandem mass spectrometry (MS) was developed to identify and characterize the diarylheptanoids in the supercritical fluid extract (SFE) of Alpinia officinarum. The method established provides good reproducibility of UPLC and shows high precision with all the mass accuracy of less than...

The hepatoprotective activity of juice of Saccharum officinarum was investigated against paracetamol (acetaminophen) induced liver damage in rats. Paracetamol (PCM) is analgesic, antipyretics drugs available as an over the counter (OTC) medication which cause hepatotoxicity as higher doses. Paracetamol at 3gm/kg induced liver damage in rats manifested by statically increased serum alanine amino...

Sugarcane cultivars are polyploid, aneuploid, interspecific hybrids between the domesticated species Saccharum officinarum and the wild relative S. spontaneum. Cultivar chromosome numbers range from 100 to 130 with approximately 10% contributed by S. spontaneum. We have undertaken a mapping study on the progeny of a selfed cultivar, R570, to analyze this complex genome structure. A set of 128 r...

Saccharum officinarum L. sugarcane, is a large, strong-growing species of grass in the genus Saccharum. It originated in Southeast Asia and is now cultivated in tropical and subtropical countries worldwide for the production of sugar and other products. S. Officinarum, a perennial plant, grows in clumps consisting of a number of strong unbranched stems..The aim of this study is to overview its ...

The genera Erianthus and Miscanthus, both members of the Saccharum complex, are of interest as potential resources for sugarcane improvement and as bioenergy crops. Recent studies have mainly focused on the conservation and use of wild accessions of these genera as breeding materials. However, the sequence data are limited, which hampers the studies of phylogenetic relationships, population str...
