Investigating the effects of dermal exposure to in-vivo animal models on the riot-control properties of a powder formulation of Tragia involucrata leaf hair lining. Cutan Ocul Toxicol 2023; 42:151-161. [PMID: 37427420 DOI: 10.1080/15569527.2023.2227255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 05/13/2023] [Accepted: 06/15/2023] [Indexed: 07/11/2023]
Abstract
Purpose: Riot control agents (RCAs) such as CS, CN, CR, PAVA, and OC, etc., are already in use and has produced numerous health risks, including skin burns, dermatitis, gastrointestinal issues, impairment of respiratory variables, conjunctivitis, etc., and even prolonged and repeated exposure may cause death. Therefore, there is a demand and need for non-lethal, non-toxic RCAs that can effectively control riots without resulting in fatal outcomes. This study was carried out to evaluate the health risks related to a novel formulation made from isolated Tragia involucrata leaf hair lining, that can be used as the best suitable non-lethal RCAs.Methods: According to the OECD guidelines, studies on acute dermal toxicity, dermal irritation/corrosion, and skin sensitisation were carried out. Wistar rats were used in an acute dermal toxicity study, and the results indicated no mortality, morbidity, or abnormal food-and-water intake, biochemical parameters, or histopathological examination findings. A study on dermal irritation in Rabbits produced moderate erythema and the effect was instantaneous and resolved within 72 hrs of post-exposure. A skin sensitisation test was conducted on Guinea pig.Results: The results showed that the formulation had moderate skin-sensitizing properties after the application of the challenge dose. Patchy erythema was seen, and it went away 30 hrs after the gauze patch was removed.Conclusion: The preclinical results did not produce any indication of severe toxicity which supports it to be used as a natural RCAs in the future.

LC-TOF-MS/MS and GC-MS based phytochemical profiling and evaluation of wound healing activity of Oroxylum Indicum (L.) Kurz (Beka). Front Pharmacol 2022; 13:1050453. [PMID: 36483735 PMCID: PMC9723245 DOI: 10.3389/fphar.2022.1050453] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Accepted: 11/08/2022] [Indexed: 09/29/2023] Open
Abstract
Background: Beka (Oroxylum indicum (L.) Kurz) has been used as a culinary herb and natural remedy by the local communities in Malaysia. The leaf of O. indicum is traditionally used for the treatment of diarrhea, high blood pressure, and improving digestive health. Objectives: The present study was conducted to evaluate the phytochemical constituents and wound healing properties (in vitro and in vivo models) of aqueous and ethanol extracts of O. indicum leaves. Methods: The total phenolic (TPC) and total flavonoid (TFC) contents in the plant extracts were determined by the spectrophotometric methods. Further, the extract was characterized by Liquid Chromatography Time-of-Flight Mass Spectrometry (LC-TOF-MS/MS) and Gas Chromatography-Mass Spectrometry (GC-MS). The wound healing activity was assessed using the in vitro scratch wound-healing assay and in vivo excisional wound model. Results: The results show the ethanol leaves extract had the higher TPC (164 mg GAE/g) when compared with the aqueous leaves extract (30 mg gallic acid equivalents/g). The ethanol leaves extract was also found to have higher TFC (101 mg Catechin equivalents/g) than the aqueous leaves extract (76 mg Catechin equivalents/g). The ethanol leaves extract was then used for further chemical analysis. The LC-TOF-MS/MS analysis showed that the leaves extracts of O. indicum contains many important compounds such as Orientin, Chrysin, Pinoquercetin, Cupressuflavone, Puerarin xyloside, Forsythiaside and Paederoside. In GC-MS analysis, 19 compounds were identified in ethanolic leaves extract. The wound healing studies shows that O. indicum has promising wound healing activity by increasing the rate of wound contraction significantly (p < 0.05). Conclusion: In conclusion, the present study showed that O. indicum leaf contains important phytochemicals and the wound healing potential of the O. indicum extract may probably be as a result of the presence of various phytoconstituents.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2020; 2020:8848676. [PMID: 33381212 PMCID: PMC7755468 DOI: 10.1155/2020/8848676] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Revised: 11/16/2020] [Accepted: 11/23/2020] [Indexed: 11/17/2022]
Abstract
Plants have been utilized as medicines to treat various ailments since ancient times. Formulations made by plant materials have been used in traditional, complementary, and alternative medicine and remain widespread in both developing and developed countries. In developing countries, traditional medicines are widely practiced due to its accessibility and affordability, while in developed countries, complementary and alternative medicine are widely popular due to the adverse effects of chemical drugs. Tragia involucrata Linn. (family: Euphorbiaceae) is a highly used medicinal plant used in both Sri Lankan and Indian traditional medical systems. Since this plant is a weed, it is being extensively destroyed due to the lack of knowledge regarding the medicinal value of this plant. Hence, the objective of this study was to collect data on the medicinal value of this plant by correlating its scientifically validated biological activities with its ethnopharmacological uses. An attempt was made to gather as much information available regarding the ethnopharmacological uses and scientifically validated biological activities of Tragia involucrata through authentic traditional texts, scientific journals, and other authentic texts regarding medicinal plants. Thus, the review provides an insight to the capability of Tragia involucrata to be used as a monoherbal formulation for diseases pertaining to multiple systems of the body. With all the scientifically validated biological activities and the ethnopharmacological uses, Tragia involucrata may qualify as a potent candidate to be developed into a phytomedicine to be utilized as both a preventive and as a therapeutic agent.

Food Chem 2020; 341:128173. [PMID: 33045585 DOI: 10.1016/j.foodchem.2020.128173] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2020] [Revised: 09/19/2020] [Accepted: 09/21/2020] [Indexed: 11/24/2022]
Abstract
A simple and rapid analytical method based on solid-phase extraction (SPE) followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) with the aid of design of experiments (DOE) approach was developed and validated for simultaneous determination of multi-class nutrients (water- and fat-soluble vitamins and flavonoids) in various food matrices (vegetables, fruits, and cereals). The factors affecting the SPE method were optimized using DOE tools. The separation was achieved in 13 min using the C18 column by gradient LC programme. The SPE-LC-MS/MS method was validated in terms of limit of detection (1.29-29.17 ng/g), linearity range (25-1000 ng/g), coefficient of determination (0.993-0.999) and recovery (72.53-104.24%) for multi-class nutrients in different food samples. Inter- and intra-day precision were evaluated and found to be within acceptable range. The developed method finds extensive application in the routine analysis of multi-class nutrients in various food matrices.

Abstract
Both plant and mammalian cells express glucuronosyltransferases that catalyze glucuronidation of polyphenols such as flavonoids and other small molecules. Oral administration of select polyphenolic compounds leads to the accumulation of the corresponding glucuronidated metabolites at μM and sub-μM concentrations in the brain, associated with amelioration of a range of neurological symptoms. Determining the mechanisms whereby botanical extracts impact cognitive wellbeing and psychological resiliency will require investigation of the modes of action of the brain-targeted metabolites. Unfortunately, many of these compounds are not commercially available. This article describes the latest approaches for the analysis and synthesis of glucuronidated flavonoids. Synthetic schemes include both standard organic synthesis, semisynthesis, enzymatic synthesis and use of synthetic biology utilizing heterologous enzymes in microbial platform organisms.
