Embodiment 1

[0068] Take fresh Cistanche deserticola (Cistanche deserticolia) fleshy stems, remove impurities, cut into 0.3cm thick slices, blanch in hot water at 100°C for 1min, take out; -40°C±5°C, pressure 2-10Pa, freeze-dry for 24 hours, that's all.

[0069] The resulting decoction pieces are light brownish yellow, and some fleshy scales can be seen, crisp in quality, with vascular bundles arranged in wavy rings on the cut surface, slightly smelly, sweet and slightly bitter.

[0070] As determined by high performance liquid phase method, the content of echinacoside in the processed Cistanche decoction pieces of the present invention is 0.44%, and the content of verbascoside is 0.32%.

Embodiment 2

[0072] Take fresh fleshy stems of Cistanche deserticola (C.tubulosa), remove impurities, cut into 1.0cm thick slices, blanch in hot water at a temperature of 80°C for 3 minutes, take out; -45°C±10°C, pressure 5-10Pa, Freeze-dry for 36 hours and freeze-dry.

[0073] The resulting decoction pieces are white, and some fleshy scales can be seen, crisp in quality, with vascular bundles arranged in wavy rings on the cut surface, slightly smelly, sweet and slightly bitter.

[0074] As determined by the high-performance liquid phase method, the content of echinacoside in the decoction pieces of Cistanche cistanche processed by the present invention is 0.486%, and the content of verbascoside is 0.73%.

Embodiment 3

[0076] Take fresh saline cistanche (C.salsa (C.A.Mey.) G.Beck) fleshy stems, remove impurities, cut into 0.7cm thick slices, steam at 100℃ for 5min, take out; -30℃±10℃, pressure 10 ~20Pa, freeze-dry for 48 hours and freeze-dry.

[0077] The resulting decoction pieces are off-white, and some fleshy scales can be seen, crisp in texture, with dot-shaped vascular bundles arranged in wavy rings on the cut surface, slightly smelly, sweet and slightly bitter.

[0078] As determined by the high-performance liquid phase method, the content of echinacoside in the decoction pieces of Cistanche tuberoside processed by the present invention is 0.54%, and the content of verbascoside is 0.37%.

Abstract

The invention provides a cistanche deserticola medicinal material processing method including the following steps: 1) impurities in a fresh Cistanche deserticola medicinal material are removed, sediment is rapidly flushed away with water, the fresh Cistanche deserticola medicinal material is cut into thick slices; 2) high temperature enzyme killing process of the thick slices obtained in step 1 is performed for 1 and 15min; 3) after heat treatment the thick slices are lyophilized. Cistanche deserticola decoction pieces processed by the method are white in color, beautiful in appearance and dry in texture, and the content of main effective constituents of echinacoside and verbascoside is 10 times greater than that of a natural drying method.

Description

technical field [0001] The invention belongs to a processing method of decoction pieces of Chinese medicinal materials, and in particular relates to a processing method of the medicinal materials of Cistanche deserticola, which improves the appearance quality of the decoction pieces and increases the content of effective components in the medicinal materials of Cistanche deserticola, echinacoside and verbascoside.
