Judul: Phylogenetic analysis of subgenus Dieramalpinia (Alpinia carolinensis clade) - Zingiberaceae based on ITS sequences
Abstrak: The most recent infra-generic classification of Alpinia Roxb. by Smith divided the genus into two subgenera (Alpinia and Dieramalpinia) with 11 sections and 12 subsections. One of the sections of Alpinia subgenus Dieramalpinia is Myriocrater which contains about 16 species. The most recent phylogenetic study that included species from Alpinia subgenus Dieramalpinia was done by Kress et al. (2007). They sampled only eight species and found that these were nested within a clade referred to as the Alpinia carolinensis clade. This clade was well supported and may be separated as a genus if sampling more species confirms the result. The objectives of the present project are to compare ITS within one species; to test the monophyly of Alpinia section Myriocrater; to test whether adding more samples still supports the Alpinia carolinensis clade. The present study included thirty-nine samples representing nineteen taxa from Alpinia; seven samples are still unidentified at species level. Sequences of the Internal Transcribed Spacer were used in the analysis. The result showed that ITS sequence of Myriocrater’s species are more conserved than another group in Zingiberaceae. There are base variations within species level. The Alpinia section Myriocrater plus five species from other section is not monophyletic. The Alpinia carolinensis clade still includes three sections of Smith classification (Dieramalpinia, Myriocrater and Pycnanthus) from subgenus Dieramalpinia. Alpinia subgenus Dieramalpinia section Eubractea and one species of section Dieramalpinia are separated into another clade.

Judul: Chemosystematics of Genus Alpinia Subsection Cenolophon through Metabolomics Appoarch
Abstrak: Alpinia merupakan salah satu genus dari Zingiberaceae yang banyak ditemukan di kawasan tropis termasuk Indonesia. Beberapa anggota Alpinia telah mengalami pengelompokan ke dalam subseksi, salah satunya adalah subseksi Cenolophon. Pendekatan morfologi telah dilakukan untuk mengelompokkan anggota subseksi tetapi perlu ada pendekatan lain untuk mempertegas pengelompokan tersebut, salah satunya adalah kemosistematik. Penelitian ini bertujuan untuk menganalisis senyawa metabolit tak tertarget pada genus Alpinia subseksi Cenolophon sebagai dasar perbedaan antar spesies dengan penanda kimia. Metode yang dilakukan berupa identifikasi morfologi, ekstraksi rimpang, analisis metabolomik dan analisis data. Identifikasi morfologi menunjukkan spesies Alpinia pusilla memiliki pangkal daun berbeda dengan spesies subseksi lainnya. Senyawa Valganciclovir, 2-hydroxyisobutyric, 8-Chlro-1-tetrahydronorharmanone, 3-FUROIC ACID, 4-Vinylphenol merupakan kandidat penanda kimia pada spesies subseksi Cenolophon. Spesies A. pusilla memiliki jarak perbedaan paling besar terhadap spesies lainnya., Alpinia is one of the genera of Zingiberaceae that is commonly found in tropical areas including Indonesia. Several members of Alpinia are grouped into subsection categories, one of which is the Cenololphon subsection. Clustering the member of the subsection based on morphological characters has been carried out but another appoarch is needed to emphasize the grouping, one of them is chemosystematics. The study aimed to analyze untargeted metabolites of the genera Alpinia subsection Cenolophon as the chemical marker basis for differentiation among species. The methods used are morphology identification, rhizome extraction, metabolomics analysis and data analysis. Morphological identification shows that Alpinia pusilla has a different leaf base from other subsection species. Valganciclovir, 2-hydroxyisobutyric, 8-Chlro-1-tetrahydronorharmanone, 3-FUROIC ACID, 4-Vinylphenol compound are candidate chemical markers in subsection Cenolophon species. Species A. pusilla has the greatest distance different from other species.
