Evaluation of phytochemical and pharmacological aspects of Holarrhena antidysenterica (Wall.): A comprehensive review

Efficacy of ground herb-based and essential oil-based phytobiotics on the intestinal health and performance of nursery pigs challenged with F18+Escherichia coli

This study aimed to evaluate the efficacy of using ground herb-based phytobiotics and essential oil-based phytobiotics in pig diets on intestinal health and growth performance (GP) of nursery pigs challenged with F18+Escherichia coli. Forty nursery pigs (6.4 ± 0.1 kg) at 21 d of age were individually housed and assigned to 4 dietary treatments in a randomized complete block design, with body weight and sex as blocking factors. Basal diets were fed to pigs for 28 d in 3 phases. Treatments were negative control (NC): basal diet, non-challenged; positive control (PC): basal diet, challenged with F18+E. coli; HP: PC + 1% ground herb-based phytobiotics (Salcochek Pro, Ayurvet Limited, Kaushambi, India); EP: PC + 1% essential oil-based phytobiotics (Liq-biotic, Ayurvet Limited). The GP was recorded for each phase and fecal score (FS) was measured daily. On day 7 postweaning, the challenged groups were orally inoculated with F18+E. coli (2.0 × 1010 CFU), the NC treatment received a sterile saline solution. On day 28, pigs were euthanized to collect jejunal samples to evaluate intestinal health and relative abundance (RA) of jejunal mucosa-associated microbiota. Data were analyzed using the MIXED procedure on SAS 9.4. The PC increased (P < 0.05) the RA of Prevotellaceae, Lachnospiraceae, and Ruminococcaceae when compared to NC. The HP reduced (P < 0.05) the RA of Veillonellaceae, Prevotellaceae, and Lachnospiraceae when compared to PC. The EP tended to reduce the RA of Streptococcaceae (P = 0.073) and Corynebacteriaceae (P = 0.074) when compared to PC. The PC increased (P < 0.05) occludin and tended to increase (P = 0.096) toll-like receptor-4 (TLR4) when compared to NC. The PC decreased (P < 0.05) average daily gain and average daily feed intake when compared to NC in days 7 to 28. The PC increased FS (P < 0.05) compared to the HP and EP days 7 to 11. The HP and EP decreased (P < 0.05) FS when compared to PC during days 7 to 11 and days 7 to 18. In conclusion, F18+E. coli challenge disrupted the jejunal mucosa-associated microbiota, increased TLR4 expression and FS, and consequently reduced GP. Both HP and EP phytobiotics supported intestinal morphology during the challenge to F18+E. coli by supporting enterocyte maturation. The HP and EP treatments exhibited antimicrobial-like effects by altering the jejunal mucosa-associated microbiota and reduced FS during the first 2 weeks post-challenge. The HP treatment showed potential antioxidant effects.

Mechanistic role and potential of Ayurvedic herbs as anti-aging therapies

INTRODUCTION

Medicinal plants and herbs are the most important part of the Ayurveda. The term Rasayana in Charaka Samhita confers long life, youthfulness, strong body, freedom from diseases and the plants mentioned in Rsayana possess antiaging property. Aging is the collective term used for the complex detrimental physiological changes that reduce the functional ability of the cell. Oxidative stress, telomeres shortening, inflammation, and mitochondrial dysfunction are the main factors that regulate the aging process. Chronological aging is an irreversible process but the factors causing biological aging can be controlled. Ayurvedic herbs are better for the management of age-related problems. There are several natural bioactive agents present in plants that can delay the aging process in humans. They trigger actions like enhancing gene longevity and telomerase activity, ROS scavenging furthermore regeneration of tissues.

CONTENT

The plants mentioned in the Rasayana of Ayurveda have antiaging potential and can be used to solve modern problems related to aging. Some Ayurvedic plants and their antiaging potential has explained in this review. The main causes of aging, medicinal plants and their use as potential antiaging mediator are covered in this study.

SUMMARY

The process of aging is still an enigma. It is a complex, irretrievable, dynamic process that involves a number of factors and is subject to a number of environmental and genetic influences. Rasayana aspect has not been much investigated in clinical trials. Aging is considered to result from free radical damage. According to Charaka, Rasayana drugs open the partially or fully blocked channels. Many Rasayanas show free radical scavenging activity and has the potential to mitigate the effects of aging. It gives an overview of the significance of Ayurvedic medicinal plants as a source of inspiration and the use of these plants as remedies for antiaging.

OUTLOOK

This study briefly outlooks the causes of aging and how medicinal plants can be used to reverse the aging process. In this study, we discussed the antiaging potential and mechanistic roles of Ayurvedic herbs. These herbs have the properties to slow down the natural process of aging and can successfully manage common age-related problems.

Bioaccumulation of industrial heavy metals and interactive biochemical effects on two tropical medicinal plant species

Concentrations of heavy metals (Cr, Cu, Fe, Mn, Ni, Pb, and Zn) accumulation were studied in the leaves of two medicinal plant species, namely Holarrhena pubescens and Wrightia tinctoria, from two industrial areas and a control area. Our comparison study revealed that industrialization significantly increased the accumulation of heavy metals in both plant species. A comparison study in control and industrial areas exhibited that heavy metal accumulation was higher in the industrially affected area than in the control area. Heavy metal concentration exceeded the permissible limit recommended by the WHO in both species of two industrial areas. However, both species accumulated the least heavy metal concentration in the control area. Biochemical investigation specifies that in response to heavy metal accumulation, both species increased the activity of hydrogen peroxide (H₂O₂), malondialdehyde content, the activity of enzymatic (superoxide dismutase and peroxidase) and nonenzymatic (ascorbic acid) antioxidant, but decreased the primary (soluble carbohydrate and total protein), secondary metabolites (phenol and flavonoid) content and free radical scavenging (DPPH) activity. This study indicates that industrialization potentially harms medicinal plants by reducing the efficacy of their medicinal property.

Holanamine, a Steroidal Alkaloid from the Bark of Holarrhena pubescens Wall. ex G. Don Inhibits the Growth of Leishmania donovani by Targeting DNA Topoisomerase 1B

Leishmaniasis is a group of neglected tropical diseases (NTDs) caused by about 20 species of obligate intracellular protozoan parasites of the genus Leishmania, which occurs in cutaneous, mucocutaneous, and visceral forms. Many researchers have sought to utilize natural products for novel and effective treatments to combat many infectious diseases, including leishmaniasis. Holarrhena pubescens Wall. ex G. Don (Apocynaceae) bark is a rich source of bioactive steroidal alkaloids. The total alkaloidal extract (IC₅₀ 6.12 ± 0.117 μg/mL), and the isolated alkaloid, holanamine, showed significant antileishmanial activity (IC₅₀ 2.66 ± 0.112 μM against AG83 and 3.80 ± 0.126 μM against BHU-575) against the Leishmania donovani parasite, better than miltefosine (IC₅₀ 19.61 ± 0.093 μM against AG83 and 23.20 ± 0.094 μM against BHU-575). Holanamine inhibited the L. donovani topoisomerase 1B (LdToP1B) in a non-competitive manner (IC₅₀ 2.81 ± 0.105 μM), indicating that it interacts with the free enzyme and enzyme-DNA complex without inhibiting human topoisomerase. Hydrogen bonding and hydrophobic interactions of holanamine with the N-terminal and hinge region of the large subunit of LTop1B is responsible for its potent antileishmanial activity, as shown by docking studies. Treatment with holanamine causes apoptotic-like cell death by generating cellular and mitochondrial reactive oxygen species, disrupting the mitochondrial membrane potential and inducing ultrastructural alterations in the promastigotes. Holanamine effectively clears intracellular amastigotes but minimally affects host macrophages with no significant cytotoxicity in HEK 293 and L929 cell lines. Thus, our studies show that holanamine can further be used to develop effective antileishmanial agents against evolving drug-resistant parasites.

Alternatives to robenidine to control gastrointestinal disorders of weaner rabbits in the field

High mortality rates and oocyst excretion are found in weaner rabbits.

Gastrointestinal disorders have multifactorial origin.

Coccidiostats are commonly used in most rabbitries.

Improve understanding of the use of alternatives to robenidine in the form of natural supplements.

Gastrointestinal disorders due to Eimeria sp. and E. coli overgrowth cause high mortality in weaner rabbits and the interest in alternatives to coccidiostats is high. This study aimed to investigate the superiority of natural feed additives towards robenidine preserving gastrointestinal health in the field. Rabbits were divided into four groups, Control Group (CG) exclusively supplemented with robenidine, Sainfoin Group (SG) was supplemented with a combination of robenidine and sainfoin, and two additional groups were respectively supplemented with Herb-All COCC-X (garlic; conessi tree) (HG: Herbal Group) and by a combination of Herb-All COCC-X and Klinofeed (clinoptilolite) (MG: Mineral Group). Eimeria sp. (98,40%) and E. coli overgrowth (73.60%) could be confirmed as the main causes for losses. High mortality rates (SG: 30.00% - MG: 47.50%), also in the groups receiving robenidine (SG: 30.00%; CG: 45.00%), reinforced the importance of alternatives in the field. The natural additives of groups SG, HG and MG did not have a significant influence on the weight gains and the oocyst counts in the jejunum/ileum and caecum of slaughter rabbits at the end of the trial, compared to group CG. Significantly higher oocyst shedding in SG (p = 1.4E-03) and HG (p = 1.4E-05) during the trial may be explained by a higher surviving rate of diseased rabbits in those groups, fostered by beneficial effects of the additives, which should be investigated further.

Adsorptive Separation of Brilliant Green Dye from Water by Tartaric Acid-Treated Holarrhena antidysenterica and Citrullus colocynthis Biowaste

Holarrhena antidysenterica (Ha) and Citrullus colocynthis (Cc) biowaste from indigenous Pakistan resources was used to remove toxic brilliant green (BG) dye from aqueous solutions in a batch mode. Tartaric acid chemical modification gave promising results than the nonmodified forms of biowaste. Surface characterization was carried out by FT-IR and SEM. The optimum conditions for (BG) dye elimination by Ha-tartaric acid modified (Ha-Ta) were 1.8 g, 45 minutes, 4.0 pH; 40°C, and 100 rpm and with Cc-tartaric acid modified (Cc-Ta) were 1.6 g, 45 minutes, 6.0 pH; 40°C, and 150 rpm dye solution shaking rate, which gave optimum results. Equilibrium data of raw and chemically modified biowaste followed the Langmuir model indicating monolayer chemisorption. Qmax values were found to be 55.24 mg/g, 112.35 mg/g, 50.50 mg/g, and 79.36 mg/g for Ha, Ha-Ta, Cc, and Cc-Ta. Kinetics followed the pseudo-second-order kinetic model. Dye removal involved surface and intraparticle mode of diffusion. Thermodynamic studies proved the process to be spontaneous and exothermic one. The adsorbents can be effectively utilized for the removal of toxic basic dyes, such as BG from wastewaters.

Tartaric Acid-Modified Holarrhena antidysenterica and Citrullus colocynthis Biowaste for Efficient Eradication of Crystal Violet Dye from Water

Two novel adsorbents Holarrhena antidysenterica (HA) and Citrullus colocynthis (CC) were collected from native Pakistan and treated with tartaric acid. The adsorbents were characterized by Fourier-transform infrared spectroscopy (FT-IR) and scanning electron microscopy, and their adsorptive behavior was studied against model cationic dye crystal violet (CV). Role of biosorbent dose, time of contact, temperature studies, agitation rates, and solution pH was investigated. Optimum conditions obtained for the removal of CV dye for H. antidysenterica-tartaric acid modified (HA-TA) were as follows: 0.8 g adsorbent dose, 35 minutes contact time, 5.0 pH, 40°C temperature, and 150 rpm agitation rates as compared to H. antidysenterica that gave 1.4 g adsorbent dose, 40 minutes time of contact, 6.0 pH, 50°C temperature, and 150 rpm agitation speed. C. colocynthis-tartaric acid modified (CC-TA) removed CV dye at 0.6 g adsorbent dose, 30 minutes contact interval, 4.0 pH, 40°C temperature, and 125 rpm agitation speed in contrast to C. colocynthis which gave 0.8 g adsorbent dose, 40 minutes time of contact, 6.0 pH, 50°C temperature, and 125 rpm agitation speed, respectively. Isothermal studies for both raw and modified biosorbents were compliant with the Langmuir model indicating monolayer, chemisorption. The maximum Langmuir capacities were up to 128.20 mg/g, 136.98 mg/g, 144.92 mg/g, and 166.66 mg/g for HA, CC, HA-TA, and CC-TA. Pseudo-second-order kinetic model well fitted the dye removal data. The rate-determining steps involved both surface and intraparticle diffusion mechanisms. Adsorption of dye molecules on active surfaces was governed by electrostatic attractions and chelating abilities. Thermodynamics research revealed the spontaneous and exothermic nature of the reaction. The adsorbents serve promising candidates for the effective removal of hazardous dyes from aqueous solutions.

Objectives:

Wrightia antidysenterica Linn. (WA) is male variety Kutaja stated to be potent therapeutic emetic agent in skin disorders. Expulsion of doshas through oral route is termed as Vamana Karma (VK) (therapeutic emesis). However, so far, its utility for Vamana is not explored in detail, therefore there is a need to revalidate the utility of WA for Vamana. Hence, the above study was conducted to ascertain the efficacy as a therapeutic emetic agent (vamaka yoga) in the management of psoriasis along with quality control and standardization of this herb.

Materials and Methods:

The drug was standardized as per analytical procedures in Pharmacopeias. Thirty patients of psoriasis fulfilling inclusion criteria were taken for the study and Vamana with WA was conducted. Criteria were prepared to assess the signs and Symptoms of psoriasis. VK was assessed using the classical Lakshanas (features) such as Anthiki shudhi (Ending symptoms of emesis), Vaigiki shudhi (features of vomiting bouts), Maniki shudhi (Quantitative and qualitative purification), complications.

Result:

VK with WA showed significant relief in parameters of psoriasis such as scaling, itching, candle grease sign (P < 0.001), and psoriasis area and severity index score (P = 0.001). In VK with WA, mean number of Vegas (vomiting bouts) was 6.91. 66% patients showing quantitative purification between 301 and 600 ml. 73.33% showed all Symptoms of purification. 73.33% patients showed Kaphanta vamana (Moderate expulsion of desire humor). In the level of biopurification, 66.66% patients showed moderated purification. No complication was noted with moderate drug palatability.

Conclusion:

Pharmacopeial analytical study showed its standardized values for testing the drug used for the study. It is proved as potent therapeutic emetic agent with no complication showed its clinical benefits over skin disorder like psoriasis.

SUMMARY

Seeds of Wrightia antidysenterica (WA) Linn. free from any foreign matter were selected for the study. Loss on drying revealed 6.535% moisture content; total ash indicating of total inorganic content was found to be 5.12%; acid insoluble ash is the acid insoluble part of total ash, mainly silica, WA showed 0.393% acid insoluble ash; ethanol and water soluble extractive is indicative of percentage active constituents were found to be 25.66 and 20.854%, respectively. High-performance thin layer chromatography fingerprinting profiles of WA under 254 nm showed the presence of 7 spots (all in green) at R_f values ranging from 0.21 to 0.88. Under 366 nm there were 4 prominent spots (all in fluorescent) at R_f 0.49 to 0.82 and, when scanned under white light 620 nm following derivatization with vanillin sulfuric acid 6 spots (in different colors) were evident at R_f 0.28 to 0.58. Among these spot with R_f of 0.58 was common when visualized under all the three methods. R_f values by densitometric scan of WA showed 12 peaks at 254 nm and 5 peaks at 366 nm. However, in clinical trial, it was found to be a potent emetic agent without any complication.

Medicinal plants used by traditional healers for the treatment of malaria in the Chipinge district in Zimbabwe

ETHNOPHARMACOLOGICAL RELEVANCE

Because about 50% of the Zimbabwean population is at risk of contracting malaria each year, the majority of people, especially in rural areas, use traditional plant-based medicines to combat malaria. This explorative ethnobotanical survey was undertaken to document how malaria is conceptualized and diagnosed by traditional healers, and to record the medicinal plants used in the prevention and treatment of malaria, their mode of preparation and administration.

MATERIALS AND METHODS

The research was conducted in three villages in Headman Muzite׳s area and in Chiriga village. These villages are located in the Chipinge district in the Manicaland Province in Zimbabwe.Traditional healers were selected with the assistance of the headman of the Muzite area and a representative of the Zimbabwe National Traditional Healers Association. Semi-structured interviews were conducted with 14 traditional healers from four villages in the Chipinge district in Zimbabwe.

RESULTS

In total, 28 plants from 16 plant families are used by the healers who manage malaria with medicinal plants. The most cited plant is Cassia abbreviata Oliv. (Leguminosae) followed by Aristolochia albida Duch (Aristolociaceae) and Toddalia asiatica (L.) Lam. (Rutaceae). Roots (55.3%) are the most common part used. Most of the plant parts used to treat malaria are stored as dried powders in closed bottles. The powders are soaked in hot or cold water and the water extract is taken as the active medicine. The healers consider their medicinal knowledge as a spiritual family heritage. Only 25% of the healers refer the malaria patients that do not respond to their treatment to hospital - they believe evil spirits cause their remedies to failure and they would rather try a different plant or perform a cleansing ceremony.

CONCLUSIONS

Local knowledge of medicinal plants in the treatment of malaria still exists in all four villages surveyed and traditional healers appear to play an important role in primary health care services in this remote rural area in Zimbabwe. This explorative survey underscores the need to preserve and document traditional healing for managing malaria and for more future scientific research on the plants to determine their efficacy and their safety. This could improve their traditional anti-malarial recipes and might contribute to a better integration of Zimbabwean traditional medicine into the national health system in the future.
