Along with this kind of use and Keyzke lily growing in the south of the Far East.
Geographical distribution.Lily of the valley growing in deciduous broad-leaved and coniferous forests are less abundant in coniferous and small-leaved forests and their derivatives.In the forest-steppe and steppe zones found on the bottom of the beams on the slopes of hills and mountains.Distributed in the European part of the USSR, except for the north-east, in the Caucasus.The main areas are blanks in Belarus, Ukraine and in many regions of the RSFSR.
collection and drying.Gather the leaves and flower arrows - "grass lily of the valley", flowers and leaves.Collection of lead during flowering, and leaves can be harvested before flowering.When harvesting grass plants are cut at a height of 3-5 cm from the soil.To keep the lily of the valley thickets, you must leave at least one plant per 1 square.m, as well as strictly to the collection of plants is not terminated and cut.When harvesting flowers bouquets tear, and then cut off the flower arrow at the bottom of the flower.
collectors must remember that the plant is poisonous.
Dried material in attics, in rooms with good ventilation or in a dryer at a temperature of 50-60 °, laying a thin layer and often poking.Drying must be carried out on the day of collection and maintained quickly, because after withering splits glycosides, and raw materials activity is sharply reduced.
medicinal raw materials.The finished raw material is of three kinds: flowers (inflorescence) - Flores Convallariae, larch Folium Convallariae grass and lily of the valley - Herba Convallariae.Each contains dry authorities described structure, however, are more likely to use the grass.
Art.GF 322 X regulates the quality of raw materials, depending on the presentation.
1. Grass.Moisture not more than 14%;inflorescences at least 5%;shredded pieces, passing through a sieve with a hole diameter of 3 mm and not more than 3%;feedstock that has lost the normal color, no more than 5%;Organic impurities are not more than 1%;mineral - not more than 0.5%.The biological activity of at least 120 ICE.
2. Leaves.The requirements are the same, except more of the inflorescences.The biological activity of at least 90 ICE.
3. Flowers.Moisture not more than 12%;inflorescences with brownish flowers no more than 5%;flower arrows having a length greater than 3 cm below the last flower, no more than 4%;solid and arrows of broken flower without flowers no more than 1%;Organic impurities are not more than 0.5%;mineral - not more than 0.3%.The biological activity of at least 200 ICE.
chemical composition.The aerial parts of lily of the valley contain at least eight cardiac glycosides, the main ones being convallatoxin, konvalla-Zid, dezglyukoheyrotoksin, vallarotoksin.Glycosides accompany steroid saponins, flavonoids (3-glyceryl
isorhamnetin glycoside, quercetin and kaempferol), organic acids, and in flowers - essential oil.Gly-glycoside convallatoxin by acid or enzymatic hydrolysis gives the sugar rhamnose and genin strofan-tidin.
action and application.The main active ingredients of drugs are the lily of the valley glycosides convallatoxin and konvallazid.First biological activity superior to other cardiac glycosides.The drugs lily primarily directed to the cardiovascular system.The mechanism of action is the same as that of other cardiac glycosides.As a result of the normalization of the heart improves renal excretory function, leading to a reduction of edema (if available).Furthermore, they have a soothing effect on the central nervous system.
Unlike lily digitalis drugs have a "soft" effect on the myocardium, less toxic and do not have the ability to accumulate in the body.They are widely prescribed for compensated vices, neuroses of the heart, thyrotoxicosis as a tincture 15-20 drops 3 times a day or preparation Korglikon containing all glycosides lily of the valley.The latter is widely used clinically in acute cardiac activity decline intravenously in combination with a glucose solution.Often drugs are lily of the valley combined with drugs valerian, motherwort, hawthorn, belladonna, bromide, menthol.
