Problems solved by technology

[0014] In view of this, on the one hand, the traditional fresh-keeping technology cannot be widely used due to the restriction of objective conditions, and it is necessary to seek a modern drying process to obtain the drying mode closest to the fresh product; There is a big difference between fresh medicine and fresh medicine in terms of preserving the active ingredients or active ingredients. It is an urgent problem to be solved to seek fresh Chinese medicine preservation technology, get rid of the seasonal restrictions of its clinical use, and retain the active ingredients or active ingredients of the medicine to the greatest extent.

Embodiment 1

[0032] Pick and cut the fresh or dry aboveground parts of Leonurus Japonicus Houtt. from the seedling stage in spring to the early flowering stage in early summer; or harvest and cut the Leonurus Japonicus Houtt. Japonicus Houtt.) fresh or dry aerial parts; remove impurities and rotten branches and leaves; rinse with running water to wash off the soil on the surface of motherwort and drain and cut into sections; pre-dry motherwort to about 80% water content and put it on a plate. The weight is 2kg / m 2 , the thickness is 2cm, and then freeze at -35°C after gradually cooling down for 2.5 hours; then vacuumize the system until the absolute pressure of the system is 75Pa, start heating to 60°C, and dry for 15 hours; then keep the material temperature at 35°C, so that the water content reaches 3% or less after discharge. Pack in a constant temperature and dehumidification workshop, and store in a cool and airtight place.

Abstract

The invention discloses a manufacturing process of leonurus. The process comprises the following steps of: selecting leonurus, washing and cutting and then draining off till the water content is 78-82%; placing the drained leonurus in a tray, wherein the weight in each tray is 2-4kg / m<2> and thickness is 2-3cm; gradually cooling for 2.5-3.2 hours and freezing at -30 to -37 DEG C; vacuumizing till the absolute pressure of the system is 70-100Pa, starting heating to 60-70 DEG C, and drying for 15-18 hours; and maintaining the temperature at 30-40 DEG C, and discharging till the water content is below 3%. The leonurus decoction piece obtained by the manufacturing process disclosed by the invention not only has the essential characteristics of fresh medicines to store the drug properties of fresh traditional Chinese medicines for a long time and ensure the effect, but also is convenient to store and convey and suitable for industrial production and clinical use. The effective components are further effectively prevented from being decomposed in the storage process, and the leonurus decoction piece has good use value and wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine production technology, and in particular relates to a processing technology of motherwort. Background technique [0002] Motherwort is the fresh or dry aerial part of Motherwort (Leonurus Japonicus Houtt.) of Lamiaceae. Fresh products are harvested from the seedling stage in spring to the early flowering stage in early summer; dry products are harvested when the stems and leaves are lush in summer, when the flowers are not blooming or just blooming, and dried in the sun or cut into sections. [0003] "Pharmacopoeia of the People's Republic of China" 2010 Edition, one part records that the medicinal materials of motherwort are divided into two categories: fresh motherwort and dry motherwort. [0004] Fresh Motherwort: Stemless at seedling stage, basal leaves are round and heart-shaped, with 5-9 lobes on the margin, and 2-3 cogs in each lobe. The stems in the early stage of fl...
