Family Solanaceae A L de Jussieu 1789 nom Conserv the Potato Family

Physical description: The family Solanaceae consists of about 85 genera and 2800 species of prickly herbs, shrubs, climbers or small trees, well represented in South America. Solanaceae are known to elaborate tropane alkaloids derived from ornithine, pyridine and steroidal alkaloids. The leaves of Solanaceae are alternate, simple, often soft, dull green and without stipules. The flowers are hermaphrodite and actinomorphic. The calyx is 4-6-lobed and persistent in fruit. The corolla is tubular, infundibuliform, showy, 5-lobed with the lobes folded, contor-tate or valvate. The andrecium consists of 5 stamens attached to the corolla, the anthers of which are 2-locular and open lengthwise or by apical pores. The gynecium consists of a pair of carpels united into a 2-locular ovary, with each locule containing several ovules attached axile placentas. The fruits are berries or capsular.

Pharmaceutical interest: Classical examples of Solanaceae are Solanum tuberosum L. (potato), Lycopersicum esculentum Mill. (tomato), Nicotiana tabacum L. (tobacco) and Capsicum frutescens L. (chilies). Notorious examples of pharmaceutical Solanales are Datura stramonium L., Datura metel L., Atropa belladonna L. and Hyoscyamus niger L., and Mandragora officinalis L., the tropane alkaloids of which are parasympatholytic. Hyoscyamine is formed from dried leaves or leaves and other aerial parts of Atropa belladonna L., collected when the plants are flowering and containing not less than 0.3% of alkaloids (Belladona Herb, British Pharmacopoeia, 1963), and from dried leaves and flowering tops of Datura stramonium L., containing not less than 0.25% of alkaloids (Stramonium, British Pharmacopoeia, 1963). The dried leaves and flowering tops of Hyoscyamus niger L., containing not less than 0.05% of alkaloids, formed as hyoscyamine (Hyoscyamus, British Pharmacopoeia, 1963),

are used in Western medicine to treat intestinal colic, gastric ulcer, spasmodic asthma, whooping cough, bladder and urethral spasms, on account of hyoscyamine. Hyoscyamine is a parasympatholytic tropane alkaloid, which exerts a selective blocking action on muscarinic receptors, resulting in mydriasis, tachycardia, decreased production of saliva, sweat, gastric juice, constipation and the inability to urinate.

In the Asia-Pacific, Capsicum annum L., Capsicum fructescens L., Datura metel L., Datura stramonium L., Lycium chinense Mill., Lycopersicum esculen-tum Mill., Nicotiana tabacum L., Physalis species, Scopolia japonica Maxim. and Solanum species are used to treat various sorts of ailments. Note that chilies produce adenocarcinomas in the abdomen of rodent.
