“…Polyketides of fungal origin have diverse structures, ranging from antibiotics to toxins [87], which are widely used in pharmacological aspects. Taechowisan et al [18] isolated two coumarins from the ethyl acetate extract of Streptomyces aureofaciens living inside the root tissue of Z. officinale, namely 5,7-Dimethoxy-4-p-methoxylphenylcoumarin (1) and 5,7-Dimethoxy-4-phenylcoumarin (2). Three years later, Taechowisan et al [19] isolated another two coumarin, umbelliferone (3) and chicorii (4), together with two flavonoids, kaempferol (5) and isoscutellarin (6), from endophytic Streptomyces sp.…”

Secondary Metabolites of Endophytes Associated with the Zingiberaceae Family and Their Pharmacological Activities

Zingiberaceae is commonly known as the ginger family and has been extensively studied in the last decades for its pharmacological purposes. The study of ginger includes microorganisms known as endophytes, which raise interest for the research community because they can produce a wide range of secondary metabolites. This review discusses the secondary metabolites of endophytes from the Zingiberaceae family and their pharmacological activities. We detail the group of secondary metabolites, updated for its absolute structures, source and part origins, and, especially, pharmacological divided properties. Zingiberaceae endophytes have 106 volatile compounds and 52 isolated constituents, including 17 polyketides, five nonribosomal peptides, five aromatic compounds, three alkaloids, and 21 terpene-alkaloids. They have antimicrobial, anticancer, antioxidant, and anti-inflammatory activities. Secondary metabolites from plant endophytes of the Zingiberaceae family have the potential to be therapeutic drugs in the future. Research on endophytic bacteria or fungi has been little performed. Therefore, this study supports a new drug discovery from Zingiberaceae endophytes and compares them for future drug development.

“…It is found throughout tropical Asia from India to South China, Southeast Asia, Papua New Guinea, and northern Australia (Dosoky and Setzer, 2018). The word "curcuma" is derived from the Arabic word "kurkum," which means yellow color (Kaliyadasa and Samarasinghe, 2019). Curcuma species are originated from the Indo-Malayan region and widespread in Asia, Africa, and Australia (Sasikumar, 2005).…”

Immunomodulatory Effects and Mechanisms of Curcuma Species and Their Bioactive Compounds: A Review

et al. 2021

View full text Add to dashboard Cite

Curcuma species (family: Zingiberaceae) are widely utilized in traditional medicine to treat diverse immune-related disorders. There have been many scientific studies on their immunomodulating effects to support their ethnopharmacological uses. In this review, the efficacy of six Curcuma species, namely, C. longa L., C. zanthorrhiza Roxb., C. mangga Valeton & Zijp, C. aeruginosa Roxb. C. zedoaria (Christm.) Roscoe, and C. amada Roxb., and their bioactive metabolites to modulate the immune system, their mechanistic effects, and their potential to be developed into effective and safe immunomodulatory agents are highlighted. Literature search has been carried out extensively to gather significant findings on immunomodulating activities of these plants. The immunomodulatory effects of Curcuma species were critically analyzed, and future research strategies and appropriate perspectives on the plants as source of new immunomodulators were discussed. Most of the pharmacological investigations to evaluate their immunomodulatory effects were in vivo and in vitro experiments on the crude extracts of the plants. The extracts were not chemically characterized or standardized. Of all the Curcuma species investigated, the immunomodulatory effects of C. longa were the most studied. Most of the bioactive metabolites responsible for the immunomodulating activities were not determined, and mechanistic studies to understand the underlying mechanisms were scanty. There are limited clinical studies to confirm their efficacy in human. Of all the bioactive metabolites, only curcumin is undergoing extensive clinical trials based on its anti-inflammatory properties and main use as an adjuvant for the treatment of cancer. More in-depth studies to understand the underlying mechanisms using experimental in vivo animal models of immune-related disorders and elaborate bioavailability, preclinical pharmacokinetics, and toxicity studies are required before clinical trials can be pursued for development into immunomodulatory agents.

“…The bioactive compounds of the turmeric rhizomes are nonvolatile curcuminoids and volatile oil. The curcuminoids include curcumin, demethoxycurcumin, and bisdemethoxycurcumin, whereas the volatile oil includes the monoterpenoids and sesquiterpenoids (Kaliyadasa & Samarasinghe, 2019). The turmeric processing comprises the unit operations namely washing, boiling, drying, polishing, and pulverizing.…”

Drying is an important unit operation in the turmeric processing chain. This research investigates the kinetics of drying turmeric slices using infrared dryer. The drying was performed at temperatures of 50, 60, and 70°C for slice thickness of 2, 4, and 6 mm. The drying temperature 70°C and slice thickness of 2 mm showed the highest drying rate. The highest curcumin and oleoresin yield with color retention was observed at the drying temperature of 60°C at 2‐mm slice thickness. Thirteen thin‐layer drying models were employed to evaluate the experimental drying kinetics of turmeric slices. The model Verma et al. showed the best fit with an R2 value of 0.99 with the least RMSE and chi‐squared values as 0.0193 and 3.73E−04, respectively. The activation energy for the turmeric slices of thickness 2, 4, and 6 mm ranged between 37.31 and 52.95, 48.78 and 57.51, and 46.79 and 57.37 kJ/mol for 50, 60, and 70°C, respectively.Practical applicationsThis research offers significant potential for improving the efficiency and quality of turmeric drying in industrial settings. The infrared drying enables accelerated drying of turmeric. The optimized infrared drying conditions (60°C and 2‐mm slice thickness) can significantly reduce drying time compared to conventional methods. This translates to increased throughput and minimized postharvest losses, especially in large‐scale turmeric processing facilities. The preservation of curcumin, oleoresin, and color at the optimized conditions ensures the production of high‐value turmeric products with superior nutritional and sensory attributes. This can lead to increased consumer appeal, brand differentiation, and potentially higher market prices for turmeric‐based foods, supplements, and nutraceuticals. The infrared drying technology can be prescribed to the industries over the existing industrial drying techniques. The cost‐effectiveness of the method, coupled with its potential for quality improvements and reduced drying time, makes it a viable option for turmeric processors seeking to enhance their operations.
