Makroalga telah digunakan industri pangan sejak lama karena komponen yang dikandungnya misalnya alginat, karagenan, dan agar. Selain itu alga mengandung nutrisi bioaktif lainnya sebagai fungsional. Kandungan protein keragaman jenis asam amino dapat menjadi informasi penting untuk memaksimalkan potensi dimiliki alga. Penelitian ini bertujuan mengetahui kandungan profil pada S.aquifolium, U. lact...

As marine seaweeds are a great source of natural products, investigating biological properties for appropriate management and exploitation is priority. For our study, we collected extracted indigenous algal samples from areas Nha Trang bay belonging to nine species Chlorophyta, Rhodophyta, Ochophyta investigate their cosmeceutical activities. Results revealed tyrosinase inhibitory activity meth...

The concentrations of abscisic acid in Grand Rapids lettuce (Lactuca sativa L.) seeds imbibed under conditions which promote or inhibit germination were determined by electron capture-gas chromatography. The concentration of abscisic acid in dry seeds was 12 to 14 nanograms per 100 milligrams. During 24-hour imbibition, the abscisic acid content diminished more rapidly during conditions which a...

THE TITLE STRUCTURE (SYSTEMATIC NAME: 9-hydroxy-methyl-3,6-di-methyl-3-methyl-ene-2,7-dioxo-3,3a,4,5,9a,9b-hexa-hydro-azu-leno[4,5-b]furan-4-yl acetate hemihydrate), C(17)H(20)O(6)·0.5H(2)O, from Lactuca floridana, has two independent sesquiterpene lactone mol-ecules in the asymmetric unit. Both have their seven-membered rings in the chair conformation. In the crystal, the OH groups and the wat...

A detailed genetic map has been constructed from the F2 population of a single intraspecific cross of Lactuca sativa (n = 9). It comprises 319 loci, including 152 restriction fragment length polymorphism (RFLP), 130 random amplified polymorphic DNA (RAPD), 7 isozyme, 19 disease resistance, and 11 morphological markers. Thirteen major, four minor linkage groups and several unlinked markers are i...
