Objective: The aim of this study was to incorporate Peraria candollei var. mirifica extract into the cream, to evaluate the physical properties and to conduct the skin tests in participants.Methods: Pueraria candollei var. mirifica was extracted with 95% ethanol to obtain crude pueraria extract (PCM). Crude PCM was developed as an anti-wrinkle PCM cream (B) intended for menopausal women. PCM cream was evaluated for stability of pH and viscosity, primary skin irritation, wrinkle reduction and moisturizing as well as customer satisfaction. Cream base (A) and cream purchased from the market (C) were used for comparison. ANOVA post hoc Turkey was used to analyze the variance (p0.05) of the mean comparisons between groups by cluster analysis. Results: The PCM cream appeared as white color, pH was 6.80, and viscosity was 4.069±0.01 Pa. s, as well as physical characteristic and texture, were acceptable and no irritating reaction. PCM cream exhibited a similar level of moisturizer as cream A and C. The PCM cream revealed an ability to decrease the wrinkle surface and wrinkle volume after applied for 7 and 14 d that shows the activity of this product performed from the PCM extract. Satisfaction of PCM cream showed good acceptance.Conclusion: These results suggest that PCM cream has the ability to reduce skin wrinkles. It is a good product for postmenopausal women and may also be of benefit for the general population for protection skin wrinkle

Nanoemulsions Containing <i>Mucuna pruriens</i> (L.) DC. Seed Extract for Cosmetic Applications

Mucuna pruriens is a medicinal plant whose seeds have various types of pharmacological activities and are used in many traditional medicines. The aim of this study was to evaluate the phytochemicals as well as the anti-aging, antioxidant, and moisturizing properties of seed extracts of M. pruriens var. pruriens and M. pruriens var. utilis. In addition, the best extract was selected for the development of nanoemulsions. M. pruriens var. utilis had the highest total phenolic and total flavonoid contents. It had good antioxidant activity (the IC50 of DPPH was 4.87 µg/mL, the FRAP value was 1.63 mg of FeSO4/mg of extract, and the percentage of lipid peroxidation was 80.19%) and anti-aging activity (the percentages of inhibition of hyaluronidase, collagenase, and elastase were 26.41%, 51.16%, and 22.78%, respectively). The occlusive factor was 46.12 ± 1.72. Therefore, M. pruriens var. utilis seed extract was selected for the preparation of nanoemulsions. The results showed that the size, PDI, and zeta potential of nanoemulsions containing M. pruriens var. utilis seed extract at day 30 did not significantly differ from those at day 0. In addition, the %EE was 63.46%. A study of skin permeation showed that the retention in the membrane after six hours of skin permeation study was 44.19%. Therefore, nanoemulsions containing M. pruriens var. utilis seed extract have good potential for further use in cosmetic applications

A Comprehensive Review of Andrographis paniculata (Burm. f.) Nees and Its Constituents as Potential Lead Compounds for COVID-19 Drug Discovery

The COVID-19 pandemic has intensively disrupted global health, economics, and well-being. Andrographis paniculata (Burm. f.) Nees has been used as a complementary treatment for COVID-19 in several Asian countries. This review aimed to summarize the information available regarding A. paniculata and its constituents, to provide critical points relating to its pharmacological properties, safety, and efficacy, revealing its potential to serve as a source of lead compounds for COVID-19 drug discovery. A. paniculata and its active compounds possess favorable antiviral, anti-inflammatory, immunomodulatory, and antipyretic activities that could be beneficial for COVID-19 treatment. Interestingly, recent in silico and in vitro studies have revealed that the active ingredients in A. paniculata showed promising activities against 3CLpro and its virus-specific target protein, human hACE2 protein; they also inhibit infectious virion production. Moreover, existing publications regarding randomized controlled trials demonstrated that the use of A. paniculata alone or in combination was superior to the placebo in reducing the severity of upper respiratory tract infection (URTI) manifestations, especially as part of early treatment, without serious side effects. Taken together, its chemical and biological properties, especially its antiviral activities against SARS-CoV-2, clinical trials on URTI, and the safety of A. paniculata, as discussed in this review, support the argument that A. paniculata is a promising natural source for drug discovery regarding COVID-19 post-infectious treatment, rather than prophylaxis

Specification and DNA Barcoding of Thai Traditional Remedy for Chronic Kidney Disease: Pikad Tri-phol-sa-mut-than

The Pikad Tri-phol-sa-mut-than (TS) remedy, a Thai traditional medicine, is officially recorded in Tamra Paetsart Sonkrau Chabub Anurak for its capabilities in treating kidney deficiency. TS remedy is composed of three fruit species—Aegle marmelos (L.) Corrêa., Coriandrum sativum L., and Morinda citrifolia L.—in an equal part by weight. The quality of the raw material is one of the essential factors that can affect the effectiveness and safety of treatment by herbal remedy. The pharmacognostic evaluation and DNA barcode of the three fruit species and TS remedy were performed in this study to authenticate them from contamination, and to provide the scientific database for further uses. Macroscopic and microscopic examination, chemical profile by TLC, and DNA barcoding were employed to positively identify the raw materials bought from the herbal market, especially the powder form. Consequently, the outcomes of this investigation can be used to develop an essential and effective tool for the authentication of crude drugs and herbal remedies

Phytochemical Analysis and Antioxidant, Antimicrobial, and Antiaging Activities of Ethanolic Seed Extracts of Four <i>Mucuna</i> Species

The investigation into promising botanical materials for natural cosmetics is expanding due to environmental and health awareness. Here, we aimed to evaluate the phytochemical substances and the potential skin-related pharmacological activities of four Mucuna seeds, namely M. gigantea (Willd.) DC. (MGG), M. interrupta Gagnep. (MIT), M. monosperma Wight (MMM), and M. pruriens (L.) DC. (MPR), belonging to the Fabaceae family. In methodology, the Mucuna seeds were authenticated using morphological and molecular approaches. L-DOPA, phenolics, and flavonoid content, incorporated with HPLC and GC–MS fingerprinting analyses, were determined. Then, skin-related antimicrobial, antioxidant, and antiaging activities were determined. The results revealed that MPR showed the highest L-DOPA content (75.94 mg/100 mg extract), whereas MGG exhibited the highest phenolic and flavonoid content (56.73 ± 0.62 mg gallic/g extract and 1030.11 ± 3.97 mg quercetin/g extract, respectively). Only MMM and MPR could inhibit all of S. aureus, S. epidermidis, and C. albicans, but no sample could inhibit C. acnes. Furthermore, all samples demonstrated antioxidant activity. Interestingly, all Mucuna samples exhibited strong collagenase, elastase, and hyaluronidase inhibitory activities. We conclude that the ethanolic extracts of four Mucuna seeds are probably advantageous in the development of skincare cosmeceutical products

Anti-Aging, Anti-Acne, and Cytotoxic Activities of Houttuynia cordata Extracts and Phytochemicals Analysis by LC-MS/MS

Although many biological properties of Houttuynia cordata have been found, its anti-aging and anti-acne effects have not yet been investigated. This study was aimed to evaluate the in vitro anti-aging and anti-acne activities of H. cordata extracts and their cytotoxic activities and phytochemicals analyzed with liquid chromatography with tandem mass spectrometry (LC-MS/MS). Dried aerial parts of H. cordata were given different extractions. The aqueous and ethanolic extracts obtained were named HCA and HCE, respectively, and used to screen total phenolic and flavonoid contents. In vitro anti-aging, skin-related antimicrobial, scanning electron microscopy (SEM), in vitro cytotoxic, and LC-MS/MS analyses were performed. The total phenolic contents of the HCA and HCE were 5.11 &plusmn; 0.25 and 27.02 &plusmn; 1.07 mg gallic acid equivalent (GAE)/g dry extract while their total flavonoid contents were 104.94 &plusmn; 5.16 and 571.86 &plusmn; 2.86 mg quercetin equivalent (QE)/g dry extract, respectively. The HCA and HCE inhibited the activities of collagenase (28.33&ndash;46.00%), elastase (30.00&ndash;34.33%), and hyaluronidase (93.87&ndash;98.72%). The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the HCA against Cutibacterium acnes DMST14916 were 5.77 and 5.77 mg/mL while those of the HCE were 2.47 and 2.47 mg/mL, respectively. Cell collapses of C. acnes after treatment with the extracts were observed with SEM. The HCE was not toxic to macrophages, keratinocytes, and fibroblasts up to 400 mg/mL. The HCA showed toxicity against macrophages at 62.5 mg/mL and both skin cells at 250 mg/mL. The main phytochemicals in the extracts were identified with LC-MS/MS. Phenolic compounds, flavonoids, and flavonoid derivatives in H. cordata extracts could be major phytochemicals to possess a broad spectrum of biological activities including antioxidant, antimicrobial, and anti-aging activities. The findings from this study showed that the HCE has potential anti-aging and anti-acne properties while having non-cytotoxic activities on the immune and skin cells. These results indicate that the extract is probably advantageous in the development of skincare cosmeceutics and beauty treatments
