alpha-Solanine Usage And Synthesis

Description

This steroidal alkaloid is present in several Solanum species including S. nigrum, S. Iycopersicum (tomato) and S. tuberosum (potato). The base crystallizes in slender needles and shrinks markedly at 235°C. It has [α]²⁰_D - 59.45° (pyridine) or - 42.16° (dilute HCl) and is readily soluble in hot EtOH, sparingly so in H20 and virtually insoluble in CHCl 3 or Et2 0. The salts are mostly amorphous although a crystalline hydrochloride has been prepared with m.p. 212°C (dec.). It is not affected by alkalies but mineral acids hydrolyze it to solanidine (q.v.) and one mole each of dextrose, galactose and rhamnose.
Pharmacologically, the alkaloid is a protoplasmic poison and a powerful haemolytic. Poisoning by potatoes sometimes occurs although the results are not usually fatal. The symptoms are nausea, headache, emesis and gastritis. With large doses parenchymatous nephritis and haemoglobinuria occurs with, at times, paralysis of the central nervous system and cardiac arrest. The alkaloid also possesses local irritant properties.

Chemical Properties

White solid

Uses

α-Solanine is produced as a by product in the synthesis of α-Chaconine. α-Chaconine is a glycoalkaloid displaying nerve toxin activity. Potential antifungal activity.

Definition

ChEBI: A glycoalkaloid poison found in species of the nightshade family (Solanaceae), such as the potato (Solanum tuberosum). It is a trisccharide derivative of solanidine [(22beta)-solanid-5-en-3beta-ol].

benefits

It has been revealed that α-solanine possesses potential chemotherapeutic action against cancers in several organs, including lung, breast, esophagus, prostate, and liver, as well as acute lymphocytic leukemia. α-solanine also has potential anti-inflammatory properties[1].

General Description

This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG

Hazard

A poison.

Side effects

A small amount of α-solanine can cause common symptoms such as dizziness, nausea, abdominal pain, vomiting, and diarrhea. Excessive consumption of α-solanine can lead to convulsions, coma, and even death. Animal studies have shown that α-solanine can damage the reproductive system[1].

Purification Methods

Recrystallise -solanine from EtOH, 85% aqueous EtOH, MeOH or aqueous MeOH as dihydrate m 276-278o. It solubility in H2O is 25mg/L and 5% in pyridine, but it is very soluble in Et2O and CHCl3. The hydrochloride is gummy or amorphous but has been crystallised (m ~212o dec). It has insecticidal properties. [Kuhn et al. Chem Ber 88 1492 1955, Beilstein 21 III/IV 1402.]
