Sorbus aucuparia

Parasorbic acid (Figure 2) was isolated from fruits of Sorbus aucuparia. Germination of mustard seed Sinapis alba) was affected adversely by parasorbic acid at 3.5 X 10-3 M and growth of excised tomato roots was inhibited at approximately 8.5 X 10 4 M (25). The acid also antagonized indoleacetic acid (IAA) in the Avena assay. Cornman 29,30) reported that parasorbic acid slowed down mitosis. Metaphase stages were observed to accumulate, but abnormalities were not detected. 

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.

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.

The ability to form biphenyl and dibenzofuran phytoalexins is confined to the Maloideae (34). Following fungal infection, a number of Maloideae species accumulated the defence compounds in the sapwood, but not in the leaves (34, 33). An exception was Sorbus aucuparia leaves that produced the biphenyl aucuparin in response to biotic and abiotic elicitation (36). Similarly, cell cultures of S. aucuparia responded to yeast extract treatment with the accumulation of aucuparin (37).

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.
