Mountain ash, Sorbus

On the other hand, borohydride reduction of the ketose o-fructose will give a mixture of o-glucitol and its epimer, D-mannitol. A better approach to D-mannitol would be reduction of the aldose D-mannose. o-Glucitol (sorbitol) is found naturally in the ripe berries of the mountain ash (Sorbus aucuparia), but is prepared semi-synthetically from glucose. It is half as sweet as sucrose, is not absorbed orally, and is not readily metabolized in the body. It finds particular use as a sweetener for diabetic products. o-Mannitol also occurs naturally in manna, the exudate of the manna ash Fraxinus ornus. This material has similar characteristics to sorbitol, but is used principally as a diuretic. It is injected intravenously, is eliminated rapidly into the urine, and removes fluid by an osmotic effect. [Pg.474]

Mountain-ash (Sorbus aucuparia L.) honey is reddish in color, with a strong aroma and pleasant flavor. [Pg.401]

Naturally occurring sorbic acid may be extracted as the lactone (parasorbic acid) from the berries of the mountain ash Sorbus aucuparia L. (Fam. Rosaceae). Synthetically, sorbic acid may be prepared by the condensation of crotonaldehyde and ketene in the presence of boron trifluoride by the condensation of crotonaldehyde and malonic acid in pyridine solution or from 1,1,3,5-tetraalkoxyhexane. Fermentation of sorbaldehyde or sorbitol with bacteria in a culture medium has also been used. [Pg.711]

Sorbitol occurs naturally in the ripe berries of many trees and plants. It was first isolated in 1872 from the berries of the Mountain Ash (Sorbus americana). [Pg.720]

MOUNTAIN ASH, Sorbus aucuparia L., Family Rosaceae has been used as a mild laxative in the form of the parasorbinic acid-containing fresh juice of the berries. Conversely the high content of pectin and tannins in the fruits means that the boiled berries can be used to treat diarrhoea. [Pg.56]

American Mountain Ash (Sorbus americana) (8x8 m/25 x 25 ft) also support lots of wildlife. With smooth, orange bark, small, white flowers, and bright red berries in winter. [Pg.145]

Inhibitors are released from roots, chiefly, but the leaves of some plants, such as Encelia farinosa, a desert shrub, contain inhibitors. If in the leaves, the inhibitor may be either leached into the soil or the leaves may fall to the ground and undergo decay. The berries of some plants are also the source of growth-inhibiting substances, such as parasorbic acid found in the mountain ash (Sorbus aucuparius). [Pg.361]

Aucuparin (22 a) was first isolated from the heartwood of mountain ash (Sorbus aucuparia, Rosaceae) where it co-occurs with methoxyaucuparin (22 b). They constitute up to 1% (dry-weight) of the wood (39, 40, 83). Their structures have been firmly established by syntheses (83). The compounds have later been found to be common wood constitutents of many Sorbus spp. (H. Erdtman, T. Norin, E. von Rudloff, unpublished results). 4-Hydroxyaucuparin (22 c) has been isolated from S. aucuparia. Chromatographic studies have shown that this compound is also present in many other Sorbus spp. (B. Kimland, T. Norin, unpublished results). [Pg.520]
