ABSTRACT

Objective:To observe the effect of Wuzi Yanzong Wan made of different processed products on the apoptosis of spermatogenic cells in rats with kidney essence deficiency, and explore its protective effect on spermatogenic cells. Method:SD rats were randomly divided into the blank group, model group, whole raw product group, pharmacopoeia group and salt-processed product group, with 8 rats in each group. The kidney essence deficiency model was replicated by giving tripterygium glycoside tablets (the dose of 20 mg·kg<sup>-1</sup>). The flow cytometry (FCM) was used to analysis the apoptosis of spermatogenic cells in testis, the immunohistochemistry (IHC) and Western blot were used to detect the expression levels of B-cell lymphoma-2 (Bcl-2) and Bcl-2 associated X protein (Bax) in the testis. High performance liquid chromatography (HPLC) was used to compare the contents of eight components (chlorogenic acid, ellagic acid, hyperoside, isoquercitrin, verbascoside, astragalin, kaempferol and schisandrin) in Wuzi Yanzong Wan made of different processed products, the mobile phase was composed of acetonitrile (A)-0.4% phosphoric acid aqueous solution (B) for gradient elution (0-5 min, 5%-15%A; 5-10 min, 15%-17%A; 10-25 min, 17%A; 25-35 min, 17%-26%A; 35-60 min, 26%-56%A), the detection wavelength was set at 254 nm. Result:Compared with the model group, the total apoptosis rate of spermatogenic cells, protein expression of Bax and Bcl-2 in each administration group were improved. Among them, the pharmacopoeia group and salt-processed product group had significant effects (<italic>P</italic><0.01), and the improvement effect of the pharmacopoeia group and salt-processed product group was significantly better than that of the whole raw product group (<italic>P</italic><0.05). The contents of chlorogenic acid, hyperoside, isoquercitrin and verbascoside in Wuzi Yanzong Wan were increased after the herbal medicines being processed with salt-water. The content of ellagic acid in the salt-processed product group increased, while it decreased in the pharmacopoeia group. The contents of verbascoside, astragalin, kaempferol and schisandrin in samples from the salt-processed product group were greater than those in samples from the pharmacopoeia group. Conclusion:Wuzi Yanzong Wan may reduce the apoptosis of spermatogenic cells in rat testis by inhibiting the expression of Bax and promoting the expression of Bcl-2, and exert its effect of nourishing kidney and enriching essence. The enhanced anti-spermatogenic effect of Wuzi Yanzong Wan after processing may be related to the changes in chemical composition content after processing.

ABSTRACT

To determine the content of extracts in different processed products of Chuanxiong Rhizoma and the content of chlorogenic acid, ferulic acid, senkyunolide Ⅰ, coniferyl ferulate, senkyunolide A and ligustilide, in order to study the effect of different proces-sing methods on the alcohol-soluble extract and the content of six ingredients of Chuanxiong Rhizoma. The extract was determined according to the alcohol-soluble extract determination method set forth in item 2201 of the 2020 Chinese Pharmacopoeia Ⅳ; the content was determined by using Agilent TC-C_(18) column(4.6 mm×250 mm, 5 μm) for gradient elution, with acetonitrile(A)-0.5% acetic acid solution(B) as the mobile phase; the column temperature was at 30 ℃; the flow rate was 1.0 mL·min~(-1), the detection wavelength was 285 nm; and the injection volume was 10 μL. Compared with Chuanxiong Rhizoma, the extracts of processed products all increased significantly; by the degree of increase, the order was stir-frying Chuanxiong Rhizoma with honey>stir-frying Chuanxiong Rhizoma with rice wine>stir-frying Chuanxiong Rhizoma with Angelicae Dahuricae Radix decoction>stir-frying Chuanxiong Rhizoma with tea decoction; the HPLC method was convenient and reliable, with a high linear relationship of chlorogenic acid, ferulic acid, senkyunolide Ⅰ, coniferyl ferulate, senkyunolide A and ligustilide, and a high precision, repeatability, stability and the sample recovery rate in Chuanxiong Rhizoma and its processed products. There were 15 chromatographic peaks before and after processing, eight of them were identified. Compared with the pre-processing, two chromatographic peaks were added after the stir-frying with honey and rice wine; and four chromatographic peaks were added after the processing with Angelicae Dahuricae Radix decoction; the contents of chlorogenic acid, ferulic acid, senkyunolide Ⅰ, coniferyl ferulate, senkyunolide A, and ligustilide in stir-frying Chuanxiong Rhizoma with rice wine were all reduced. Except for the content of ferulic acid that increased, the content of the other five components decreased in stir-frying Chuanxiong Rhizoma with honey, stir-frying Chuanxiong Rhizoma with tea decoction, and stir-frying Chuanxiong Rhizoma with Angelicae Dahuricae Radix decoction. Rice wine, honey, decoction of tea and Angelicae Dahuricae Radix could all promote the dissolution of chemical components in Chuanxiong Rhizoma, and increase the content of extract; the changes in the contents of six components of different processed products could provide a certain basis for studying chemical composition and efficacy of different processed products of Chuanxiong Rhizoma.
