Fom the stem wood of Dracaena loureiri, a new homoisoflavanone named loureiriol (1) and eight known flavonoid and stilbenoid derivatives, including 5,7-dihydroxy-3-(4-hydroxybenzyl)-4-chromanone (2), 4,4'-dihydroxy-2,6-dimethoxydihydrochalcone (3), 2,4'-dihydroxy-4,6-dimethoxydihydrochalcone (4), 4'-hydroxy-2,4,6-trimethoxydihydrochalcone (5),(More)
From the twigs of Miliusa mollis Pierre, three new compounds including (2S,3S)-2,3-dihydro-2-(4-methoxyphenyl)-3-methyl-5-[1(E)-propenyl]benzofuran, (7S,8S)- threo-Delta8'-4-methoxyneolignan and tyrosol-1-O-beta-xylopyranosyl-(1-->6)-O-beta-gluco-pyranoside were isolated, along with seven known compounds. Their structures were elucidated through analysis of(More)
The aim of this study was to isolate a novel amylomaltase gene from community DNA of soil samples collected from Ban Nong Khrok hot spring in Thailand without bacterial cultivation. Using PCR, a 1.5 kb full-length gene was amplified and ligated with pGEM®-T easy vector to transform into Escherichia coli DH5 α for sequencing. The obtained gene encoding an(More)
From the leaves of Miliusa mollis Pierre (Annonaceae), five new dihydrobenzofuran neolignans, namely miliumollin, 7-methoxymiliumollin, 3'-methoxymiliumollin, 4'-O-methylmiliumollin and miliumollinone, and a new 8-O-4' neolignan named miliusamollin were isolated, and their structures were elucidated through analysis of spectroscopic data. Miliumollin,(More)
