520 $a Since the last decade, functional foods or nutraceuticals has been one of the hottest areas in the food industry. They can provide additional health benefits beyond basic nutrition, such as against cancers, heart diseases, diabetes, inflammation, microbial, viral and parasitic infections, psychotic diseases, and spasmodic conditions. These health functions have been widely examined and supported by numerous <italic>in vitro</italic> and <italic> in vivo</italic> studies. Despite the definition difference between functional foods and nutraceuticals, both of them provide health benefits for disease treatment or prevention because of their physiologically active components. Of all the active components, phytochemicals (components from plants) in foods and in isolated forms play a key role in the current functional food or nutraceuticals industry.
520 $a In our preliminary studies, the extract of myrrh and unprocessed guggul gum showed significant cytotoxicity against breast cancer cell lines. Furthermore, quinoa seeds have been considered as a healthful food with potential health benefits. Therefore, we systemically investigated the chemical components of unprocessed guggul gum, myrrh, and quinoa seeds, to provide the needed scientific rationale for their use in the food and their possible health benefits on luiman beings.
520 $a Seventeen compounds were isolated from the ethyl acetate extract of unprocessed guggul gum. Among them, four are new ferulates, which were determined as (<italic> z</italic>)-5-tricosene-1,2,3,4-tetraol and (<italic>z</italic>)-5-tetracosene-1,2,3,4-tetraol, (<italic>z</italic>)-5-pentacosene-1,2,3,4-tetraol and (<italic>z</italic>)-5-hexacosene-1,2,3,4-tetraol; two are new triterpenoids, determined as (8R)-3-oxo-8,21-dihydroxy-22-methyl-polypoda-13E,17E-dien-29-acid and (8R)-3-oxo-8,21,22-trihydroxy-polypoda-13E,17E-diene.
520 $a From the ethyl acetate extract of myrrh, a total of sixteen compounds have been isolated and fifteen of them were identified. Of the identified compounds, three are new sesquiterpenoids: <italic>rel</italic>-1S,2S-epoxy-4R-furanogermacr-10(15)-en-6-one, <italic> rel</italic>-2R-methyl-5S-acetoxy-4R-furanogermacr-1(10)Z-en-6-one, and myrrhone; two are new triterpenoids: 3β,20(R)-dihydroxydammar-24-en-23-one, 3β-dihydroxydammar-20(22),24-dien-23-one.
520 $a From debittered quinoa seeds, a total of twenty-seven compounds, including five ecdysteroids, six flavonol glycosides, ten triterpene saponins, and two phenolic glycosides, have been isolated and identified. Three new compounds were determined as 3-<italic>O</italic>-β-D-glucopyranosyl-(1 → 3)-α-L-arabinopyranosyl-30-<italic>O</italic>-methyl spergulagenate 28-<italic>O</italic>-β-D-glucopyranosyl ester, quinoside A and quinoside B.
