Ccxcvi. Cress Seed Mucilage
THE dispersed cellulose component which is found in white mustard seed mucilage [Bailey and Norris, 1932] and in quince seed mucilage [Schmidt, 1844; Kirchner and Tollens, 1874; Renfrew and Cretcher, 1932] has now been obtained from the mucilage of cress seed, Lepidium sativum. The present communication, which deals mainly with the chemistry of this seed mucilage, falls into three sections: (1)...
متن کاملPlant mucilages. XL. A representative mucilage, "Hibiscus-mucilage SF," from the flower buds of Hibiscus syriacus.
A representative mucilage, named Hibiscus-mucilage SF, was isolated from the white flower buds of Hibiscus syriacus L. It was homogeneous on electrophoresis and gel chromatography. Its intrinsic viscosity value in aqueous solution was 26.0. It is mainly composed of partially acetylated acidic polysaccharide of molecular weight 1050000, and is composed of L-rhamnose : D-galactose: D-galacturonic...
متن کاملThe Mucilage of the Seed of White
IN comparison with the immense bibliographies of starch and cellulose for example, the literature of the gums and mucilages is scanty. This, doubtless, is due in part to the great commercial importance of the former, but a contributory cause may be sought in the practical difficulties involved in dealing with the latter. The gums Und mucilages are complex colloids which are not infrequently fou...
متن کاملPrenylated stilbenes from peanut root mucilage.
Seven prenylated stilbenes were identified by combined HPLC-PAD-APCI/MSn analysis of an extract of mucilage isolated from peanut (Arachis hypogaea L.) root tips. The principal constituent was assigned the structure 4-(3-methyl-but-1-enyl)-3, 5-dimethoxy-4'-hydroxy-trans-stilbene. The common name mucilagin A is proposed for this novel compound. Its concentration in the mucilage was estimated at ...
متن کاملEffective extraction of Arabidopsis adherent seed mucilage by ultrasonic treatment
The Arabidopsis seed coat is composed of two layers of mucilage, a water-soluble non-adherent outer layer and an adherent inner layer. The non-adherent mucilage can easily be extracted by gentle shaking. However, adherent mucilage is extremely difficult to dissociate from the seed coat. Despite various treatments to extract the adherent mucilage, including EDTA, ammonium oxalate, dilute alkali ...
