[Quality status of Bombyx Batryticatus and suggestions for Chinese Pharmacopoeia (2025)].

To understand the current quality status and rearing situation of Bombyx Batryticatus, the authors collected 102 batches of Bombyx Batryticatus from different main producing areas and five major Chinese medicine markets from 2016 to 2018, and measured the properties and quality of the silk gland, to clarify the quality status of Bombyx Batryticatus from different producing areas and markets. In addition, 35 batches of Bombyx Batryticatus from 2019 to 2022 were used to verify the silk gland after revision. Moreover, Beauveria Bassiana was inoculated in the silkworm of 4-5 instars, and standardized rearing was carried out until they die. The death rate and the quality of Bombyx Batryticatus were measured to determine the differences in Bombyx Batryticatus of different instars, and explore the rationality of the infection age of Bombyx Batryticatus in Chinese Pharmacopoeia(2020). The results revealed that in the 102 batches of Bombyx Batryticatus, the qualification rate of silk gland was low; the content of total ash far exceeded the standard; the content of beauvericin varied greatly. The qualification rate of the silk gland of the 35 batches of Bombyx Batryticatus was only 47.49%, which could be increased to 73.00% if the number of silk gland was 2 to 4. The death rate of Bombyx Batryticatus at different infection ages was quite different, with uneven quality. Generally, the yield of Bombyx Batryticatus inoculated on the first day of the fifth instar was high with good quality. Therefore, in combination with the quality and actual production of Bombyx Batryticatus, the following suggestions were proposed for revision of Bombyx Batryticatus in Chinese Pharmacopoeia(2025): The number of silk gland should be revised as 2-4 bright brown or bright black silk glands, after which, the quality of Bombyx Batryticatus could be guaranteed, and the "quality identification based on character" could also be reflected scientifically; the content determination index that the content of beauvericin shall not be less than 0.017% should be added to better control the quality of Bombyx Batryticatus; the infection age should be revised as the first day of the fifth instar to narrow the age span, which could better fit the actual production and ensure the quality of Bombyx Batryticatus.

Studies on cultivation of Angelica acutiloba using paper pot (Part 2): effect of difference in taproot base diameter of seedlings on growth after planting and quality of toki produced from paper pot seedlings.

By using Angelica acutiloba seedlings produced by short-period raising in paper pot (PP), we investigated the effect of taproot base diameter on the growth after planting and evaluated the quality of toki (, Angelicae Acutilobae Radix) produced from PP-grown seedlings (PT). In this study, PP-grown seedlings of seven classes which are sorted difference taproot base diameter (P1-P7) were transplanted. As a result, the survival rates were not less than 90% for P6 (taproot base diameter: 10.0-12.7 cm) and P7 (taproot base diameter: 12.8-17.3 cm), and the bolting rates were 20.5% and 24.1% for P6 and P7, respectively. The traditionally grown seedling (TS) showed the highest available harvest rate of 82.3%, followed by P6 (71.8%) and P7 (69.0%). P7 showed the highest fresh weight and dry weight per 1a (100 m2), followed by P6 and TS. However, PP-grown seedlings are prone to bolting, and it is expected the yield can be increased by preventing bolting. In addition, PT satisfied the regulations of JP17 in terms of, for example, dilute ethanol-soluble extract content, total ash content, and acid-insoluble ash content. It was also found that PT has a higher proportion of lateral roots with respect to the total weight than toki produced from traditionally grown seedlings (TT). The total (Z)-ligustilide contents were 0.07% in PT and 0.12% in TT. It was revealed that it is possible to produce toki that satisfies JP17 regulations; moreover, the period required for toki production was shortened by 6 months with PP-grown seedlings.

Effect and Underlying Mechanism of Sulfur-fumigation and Water-soaking on Total Ash of Dioscoreae Rhi-zoma / 中国药师

Objective:To study the effect and underlying mechanism of sulfur-fumigation and water-soaking on total ash of Di-oscoreae Rhizoma, find the key factor( s) affecting the total ash of Dioscoreae Rhizoma, and explore the rationality of ash limits of Di-oscoreae Rhizoma described in Chinese Pharmacopoeia. Methods:Dioscoreae Rhizoma was respectively dealt with sulfur-fumigation and water-soaking. The changes in total ash content of Dioscoreae Rhizoma was detected by the ash determination methods for total ash and SO2 described in the pharmacopoeia, and then the ash content change of inorganic salts was used to study the mechanism. Results:Sulfur-fumigation could slightly reduce the total ash content of Dioscoreae Rhizoma, while significantly reduce the ash content of calcium oxalate and calcium sulfate with the reduction degree of 7. 20% and 9. 90%, respectively. Calcium phosphate and calcium chloride were slightly affected by sulfur-fumigation, and the results indicated that the effect of sulfur-fumigation on ash content was mainly real-ized by increasing the decomposition rate of calcium oxalate and calcium sulfate. Water-soaking could decline the ash content of Di-oscoreae Rhizoma, and the phenomenon was common in the rhizome medicinal materials. The influence of water-soaking on total ash was more significant than that of sulfur fumigation. Conclusion:Sulfur-fumigation can reduce the total ash content of Dioscoreae Rhizo-ma by increasing the decomposition rate of calcium oxalate and calcium sulfate, however, the effect is mild and the process isn't the key influencing factor in the total ash content of Dioscoreae Rhizoma. During the preparation of Dioscoreae Rhizoma medicinal slices, water-soaking can cause the great loss of water-soluble mineral salts, such as Cl-, C2 O4 2-, NO3 - and SO4 2-, which leads to the reduction of total ash content, therefore, water-soaking is the key influencing factor in the total ash content of Dioscoreae Rhizoma.
