Embodiment 1

[0031] The storage of embodiment 1, Angelica dahurica seeds

[0032] 1) The seeds of Angelica dahurica are dried, and the water content is adjusted to three different water contents of 5.34%, 7.70% and 9.43%, and then the seeds with different water contents are placed in airtight aluminum boxes for later use.

[0033] 2) The seeds of Angelica dahurica with different water contents in the above 1) are mixed with dimethyl sulfoxide, glycerin, polyethylene glycol 400 (PEG400) respectively as antifreeze protectant (the quality of Angelica dahurica seeds and antifreeze protectant is as shown in Table 1) shown), and then put them in plastic centrifuge tubes (with lids) and plastic ziplock bags (0.1mm thick), and store them in the following three ways:

[0034] Quick freezing: liquid nitrogen;

[0035] Slow freezing: refrigerator (5°C, 0.5h)-refrigerator (-20°C, 4h)-liquid nitrogen;

[0036] Slow freezing: refrigerator (5°C, 0.5h)-refrigerator (-20°C, 1h)-liquid nitrogen.

Abstract

The invention discloses a method for storing an angelica dahurica seed at an ultralow temperature. The method comprises the following steps: 1) drying the angelica dahurica seed to obtain a dried seed; 2) sealing and packaging the dried seed, and freezing and storing the dried seed to obtain a frozen seed; 3) storing the frozen seed in an unfreezing manner. The method for storing the angelica dahurica seed, provided by the invention, is simple and feasible; with the method, the influence on the germination rate, the conductivity, the peroxidase (POD) activity and the soluble protein content of the angelica dahurica seed is small.

Description

technical field [0001] The invention relates to a method for ultra-low temperature storage of Angelica dahurica seeds, which belongs to the field of traditional Chinese medicine seed storage. Background technique [0002] Angelica dahurica (Fisch.ex Hoffm.) Benth.etHook.f) or Hang Baizhi (Angelica dahurica (Fisch.ex Hoffm.) Benth.etHook.f.var.formosana (Boiss.) Shan et Yuan), because the primary root stalk is Zhi, the color is white, so it is called Baizhi, and the root is used as medicine. Tongqiao analgesia, swelling and pus drainage and other effects, can be used for both medicine and food. According to statistics, there are more than 600 kinds of prescription preparations composed of Angelica dahurica, which occupy an important position in Chinese medicinal materials. Famous prescriptions of past dynasties such as Jiuwei Qianghuo Decoction, Huoxiang Zhengqi Powder, etc. all have their medicinal properties. Angelica dahurica is an authentic medicinal material produced ...
