Abstract
From 2012 to 2017, many adverse events, such as irregular vaginal bleeding and menstrual disorders, associated with the use of health foods containing Pueraria mirifica were reported in PIO-NET. Health foods containing P. mirifica claim mastogenic or body shaping effects, and it is for this reason that many women use these products. As a result, the Japanese government investigated and assessed the possibility of the occurrence of adverse effects associated with the use of other ingredients in health foods and labelled P. mirifica, Coleus forskohlii, black cohosh, and greater celandine as "designated ingredient, etc."The present study showed that recognition of "designated ingredient, etc." was 45.9% and that there was a difference between consumers and healthcare professionals. The prevalence of food containing P. mirifica use was 1.2%. Almost half of users experienced adverse events, such as irregular vaginal bleeding and menstrual disorder. Some subjects had a good perception towards "designated ingredient, etc.," such as "It seems effective"(32.7%) and "It seems good for health"(18.9%). After reading the descriptive text, their positive perceptions decreased.In conclusion, the recognition of "designated ingredient, etc." is insufficient. To avoid adverse events associated with "food containing designated ingredient, etc.," detailed information should be provided.

Abstract
The presence of specific gut microflora limits the biotransformation of Pueraria mirifica isoflavone (PMI) glycosides into absorbable aglycones, thus limiting their health benefits. Cellulolytic enzyme-assisted extraction (CAE) potentially solves this issue; however, solvent extraction requires recovery of the hydrophobic products. Here, we established the simultaneous transformation and extraction of PMIs using cellulolytic enzymes and natural deep eutectic solvents (NADESs). The NADES compositions were optimized to allow the use of NADESs as CAE media, and the extraction parameters were optimized using response surface methodology (RSM). The optimal conditions were 14.7% (v/v) choline chloride:propylene glycol (1:2 mol ratio, ChCl:PG) at 56.1 °C for the cellulolytic enzyme (262 mU/mL) reaction in which daidzin and genistin were extracted and wholly transformed to their aglycones daidzein and genistein. The extraction of PMIs using ChCl:PG is more efficient than that using conventional solvents; additionally, biocompatible ChCl:PG enhances cellulolytic enzyme activity, catalyzing the transformation of PMIs into compounds with higher estrogenicity and absorbability.

Abstract
Pueraria candollei var. mirifica (PM) has a significant beneficial effect on postmenopausal symptoms associated with estrogen deficiency. However, the estrogenic activity and intestinal absorption of isoflavonoid glycosides derived from PM, such as daidzin and genistin, are significantly lower than those of their aglycones. To enhance the estrogenic activity of the PM extract, we developed β-glucosidase and its immobilized form to increase the PM aglycone content (daidzein and genistein). The enzyme immobilization was done by alginate beads, and the resulting β-glucosidase alginate beads have a diameter of about 0.20 cm. Response surface methodology (RSM) was used to optimize certain parameters, such as the pH, temperature, and ethanol concentration. The optimal conditions of β-glucosidase for daidzein and genistein production were pH of 4.8–4.9, a temperature in the range 46.3–49.1 °C, and ethanol concentration of 10.0–11.0%. The ANOVA results indicated that the design experiment involving free and immobilized β-glucosidase was the best fit by quadratic models, which had adjusted R2 values between 0.8625 and 0.9318. Immobilized β-glucosidase can be reused up to nine times and maintained efficacy of greater than 90%. Treatment of the PM extract with β-glucosidase increased the estrogenic activity of the PM extract by 8.71- to 23.2-fold compared to that of the untreated extract. Thus, β-glucosidase has a high potential for enhancing the estrogenic activity of PM constituents, and it can be applied on an industrial scale to increase the utility of these natural products. Transformation of Pueraria candollei var. mirifica phytoestrogens by β-glucosidase increases estrogenic activity.![]()

Abstract
INTRODUCTION Kwakhurin (Kwa) is one of the unique isoflavonoids produced in Pueraria candollei var. mirifica (P. candollei), which has long been used as folk medicine for rejuvenation in Thailand. Recently, the use of P. candollei-derived products has widely spread among Japanese women for cosmetic purposes. Correspondingly, there has been an increase in the number of reports regarding possible health hazards caused by estrogenic activity inherent to the plant; thus, the need for a detailed evaluation of the phytoestrogen content of P. candollei-derived products has gained a sense of urgency in recent years. OBJECTIVE This study aims to develop a rapid enzyme immunoassay that can be applied to the quantitative analysis of Kwa in P. candollei and its derived products. MATERIAL AND METHOD A rapid and sensitive immunoassay was developed with a combination of Kwa-specific monoclonal antibody (MAb 11F) and Kwa-magnetic particles (MPs) conjugates, which increased the surface area of the solid phase, resulting in a decrease in the immunoreaction time. RESULT This novel MPs-based enzyme immunoassay (MPs-EIA) was used to determine Kwa concentration in the range from 2.44 to 78.1 ng/mL with a limit of detection of 1.90 ng/mL. Validation analyses revealed that the proposed MPs-EIA protocol was sufficiently precise and accurate for effective quantitative analysis of Kwa in P. candollei and its derived products.

Quantification of methylisomiroestrol, a phytoestrogen of Pueraria candollei, by enzyme-linked immunosorbent assay in comparison with high-performance liquid chromatography. J Pharm Biomed Anal 2020; 192:113674. [PMID: 33120305 DOI: 10.1016/j.jpba.2020.113674] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Revised: 09/24/2020] [Accepted: 10/03/2020] [Indexed: 11/22/2022]
Abstract
Pueraria candollei is a phytoestrogen-rich herb used to treat estrogen deficiency disorders; however, quality control of P. candollei-related health products is required for consistency of clinical outcomes. Estrogenically active (+)-7-O-methylisomiroestrol could be a potential chemical marker that facilitates the prediction of the overall estrogenic activity of P. candollei. The analytical performance of ELISA using newly produced monoclonal antibodies against methylisomiroestrol was compared with HPLC analysis. The developed indirect competitive ELISA (icELISA) was highly sensitive to methylisomiroestrol for detection, with an LOQ of 2.9 ng/mL, whereas the LOQ was 1.15 μg/mL by HPLC. The results from method validation indicated acceptable precision (1.71-6.37 % and 0.13-2.40 %) and accuracy (99.23-102.54 % and 96.84-101.88 %) of the methylisomiroestrol analysis using icELISA and HPLC. These methods were effectively applied for the determination of the methylisomiroestrol content in P. candollei samples. Apart from the plant tubers, the stem was observed as a source of methylisomiroestrol. The developed ELISA was more effective than HPLC in detecting a small quantity of methylisomiroestrol in the plant samples [0.23 × 10-3% (w/w) to 0.628 × 10-3% (w/w) dry weight]. Therefore, the ELISA could be a useful tool for the standardization of P. candollei, which is the crucial step to improve the quality of plant-derived products.

Expression of actively soluble antigen-binding fragment (Fab) antibody and GFP fused Fab in the cytoplasm of the engineered Escherichia coli. Mol Biol Rep 2020; 47:4519-4529.

Abstract
The expression of recombinant antibody fragments in the cytoplasmic space of Escherichia coli and the refolding process for restoring the structure and activity of such antibodies are not efficient. Herein, fragment antigen-binding (Fab) antibodies against miroestrol and deoxymiroestrol (MD-Fab) and their fusions with a green fluorescent protein (GFP) were expressed. The reactive MD-Fabs were successfully expressed as soluble and active forms in the cytoplasm of the SHuffle® T7 E. coli strain. Regarding the construct of MD-Fab alone, VH-CH1 could associate VL-CL into Fab in the oxidizing cytoplasm of the E. coli strain, and no additional in vitro refolding was needed. In the case of the fusions with GFP, when the C-terminus of VH-CH1 was linked with the N-terminus of GFP, the MD-Fab binding reactivity was retained, but the fluorescent activity of GFP interfered. When the C-terminus of GFP was linked to the N-terminus of VL-CL, the binding activity of MD-Fab was not observed. The constructed MD-Fabs had higher specificity toward deoxymiroestrol than the parental monoclonal antibody clone 12G11. In conclusion, MD-Fabs could be expressed using SHuffle® T7 E. coli cells. This process could be considered an economical, productive, and effective method to produce antibody fragments for immunoassay techniques.
