Lonicerae Japonicae Flos was one of the most widely used traditional Chinese medicine for its special biological activities. The content of luteoloside, one of its major compounds, was an important standard for the quantity control of Lonicerae Japonicae Flos. The major method used for the detection of luteoloside was instrumental analysis. Compared with the ELISA method, instrumental analysis was time-consuming, complex pretreatment and low-throughout. Thus, it was significantly important to develop an enzyme-linked immunosorbent assay (ELISA) for luteoloside analysis. Here, the conjugates of luteoloside-bovine (LG-BSA) and luteoloside-ovalbumin (LG-OVA) were produced as the immunogen and coating antigen by the carbodiimide ( CDI) method, respectively. The conjugation ratio of carrier protein and the hapten in the conjugate were determined by UV-Vis spectrophotometry (UV). LG-BSA conjugate was used to immunize Bal b/c mice to produce antiserum. The titer and specificity of antiserum were detected by ELISA. The conjugation ratio of hapten and carries protein were 3. 7: 1 (LG-BSA) and 1. 0: 1 (LG-OVA). The antiserum titer was higher than 2 000 with the linear range of 18.4-4 852.4 μg x L(-1), R2 = 0.988 4 and IC50 = 298.7 μg x L(-1). The result showed that the conjugate antigen LG-BSA was synthesized successfully and the mice can produce specific antiserum injected with artificial antigen.

By consulting ancient herbal medicines, medical and prescription books, combined with modern documents, the textual research of Morindae Officinalis Radix has been conducted to verify the name, origin, changes in production areas, quality evaluation, harvesting, and processing methods, so as to provide reference and basis for the development and utilization of the famous classical formulas. After textual research, the production areas of Morindae Officinalis Radix has experienced great changes from north to south in history. The original plants involve 11 families, 14 genera and 21 species, and the mainstream varieties in ancient times were Damnacanthus officinarum and D. indicus, and the basis of Morindae Officinalis Radix in modern times has changed into the dry roots of Morinda officinalis produced in Guangdong province and other places. The medicinal parts of Morindae Officinalis Radix in ancient and modern times are all roots, and the quality is better if it has many beads, thick flesh, and purple color. Ancient medical books recorded that it was usually harvested in February and August, dried in the shade, and used to remove the wood core. And the modern harvesting and processing method is to dig throughout the year, first remove the fibrous roots, dry in the sun until 60%-70% dry, gently beat flatten and dry in the sun. The processing methods of the past dynasties are mainly salt-, vinegar-, wine-processed, etc. Based on the systematic research of Morindae Officinalis Radix, from the perspective of clinical experience and safety and effectiveness, it is recommended that the famous classical formulas should be developed from the mainstream variety since modern times, namely Morindae Officinalis Radix.

By consulting ancient herbal medicines and medical books, combined with modern documents and field investigations, the textual research of Pheretima has been conducted to verify the name, origin, producing area, quality, harvesting and processing changes, and sort out the relationship of origin between ancient and modern times, so as to provide reference and basis for the development and utilization of the related famous classical formulas. Through textual research, it is known that there are many aliases for Pheretima, the rectification of name was "Qiuyin" or "Baijing Qiuyin" in materia medica books. In the Song dynasty and later prescription books, the prescription name is mostly Dilong. From the beginning of Yaowu Chuchanbian (《药物出产辨》), Dilong was used as the rectification of name. It is widely distributed in our country, which is produced all over the country and mostly wild. According to ancient Pheretima with "Baijing Dilong", "Jingbai Shenzi" and "Datiao" as the principles of medicine, combined with historical origin, producing area and easy access, it is confirmed that Pheretima used in ancient times to the present is mainly Pheretima aspergillum, and it also has many other Qiuyin as Pheretima for medicinal purposes. Chinese Pharmacopoeia has unified the origin of the Pheretima since the 1995 edition based on historical origins and actual harvesting conditions. The medicinal material processed by P. aspergillum was called Guangdilong, and the medicinal materials processed by P. vulgaris, P. guillelmi and P. pectinifera were called Hudilong. Since then, all the herbal books published in the future are in line with Chinese Pharmacopoeia that was implemented at that time. The authentic production areas of Guangdilong are Guangdong and Guangxi, and the authentic production areas of Hudilong is Jiangsu, Shanghai, Zhejiang and Anhui. The Guangdilong produced in Guangdong and Guangxi has the best quality. After harvesting, remove the soil and offal, wash and dry. Clinically cut into sections for medicine, or prepare medicine according to prescription. The Pheretima in ancient used "Baijing Dilong", "Jingbai Shenzi" and "Datiao" as the mainstream quality evaluation standards. According to historical origins, P. aspergillum should be the main source of Pheretima, and its quality is better than other species. Therefore, it is recommended that Pheretima in Shentong Zhuyutang use P. aspergillum, which is produced in Guangdong, Guangxi and other places. After harvest, the abdomen was opened in time to remove the viscera and sediment, washed and dried.

By consulting ancient Chinese herbal medicines and medical books, combined with modern documents, the textual research of Polygonati Rhizoma has been conducted to verify the name, origin, bitter-flavored Polygonatum species, Latin name evolution, origin, quality evaluation, harvesting and processing changes, so as to provide reference and basis for the development and utilization of the famous classical formulas. Through textual research, it can be seen that there are many other names for Polygonati Rhizoma, and Huangjing is the correct name since Mingyi Bielu. Based on the original research, it is concluded that P. sibiricum and P. cyrtonema were the mainstream of Polygonati Rhizoma before the Tang dynasty, and P. kingianum was added in the Qing dynasty. According to the shape of medicinal materials, these Polygonatum species were called Jitou Huangjing, Jiangxing Huangjing and Dahuangjing. The harvest time of Polygonati Rhizoma is spring and autumn. After harvest, it is steamed and dried in the sun, and its processing method is mainly "nine steaming and nine storms". Bitter-flavored Polygonatum is mainly P. cirrhifolium, P. zanlanscianense, P. curvistylum and P. verticillatum, which are not suitable for medicine. Based on textual research, it is recommended that when developing famous classical formulas and health products with Polygonati Rhizoma as the main raw material, the origin and producing area should be clear and fixed, and P. sibiricum or P. cyrtonema with clear origin should be used. It is necessary to conduct germplasm survey and sampling in the producing area, establish a planting base and a traceability system for Polygonati Rhizoma, in order to control the quality and stabilize the efficacy of the products. The processing method of Polygonati Rhizoma can be determined according to the product function positioning.
