“…Kaempheria species were documented as very rich plants with volatile oils such as K. galanga [29,73,82,83], K. angustiflora [29], and K. marginata [29]. The volatile oil of K. galanga has been reported as a potential market product in India and over all the world with market values around 600–700 US$/kg on the international market [83].…”

“…The volatile oil of K. galanga has been reported as a potential market product in India and over all the world with market values around 600–700 US$/kg on the international market [83]. Phenylpropanoids and/or cinamates were represented as major constituents of volatile oils derived from Kaempheria species followed by monoterpenes [29,73,82]. The phenylpropanoid compound, trans-ethyl cinnamate, was documented as a principal component of volatile oils of all the studied Kaempheria species up to date with concentrations varied from 16–35% of the total identified [29,73,82,83].…”

Background: Plants belonging to the genus Kaempferia (family: Zingiberaceae) are distributed in Asia, especially in the southeast region, and Thailand. They have been widely used in traditional medicines to cure metabolic disorders, inflammation, urinary tract infections, fevers, coughs, hypertension, erectile dysfunction, abdominal and gastrointestinal ailments, asthma, wounds, rheumatism, epilepsy, and skin diseases. Objective: Herein, we reported a comprehensive review, including the traditional applications, biological and pharmacological advances, and phytochemical constituents of Kaempheria species from 1972 up to early 2019. Materials and methods: All the information and reported studies concerning Kaempheria plants were summarized from library and digital databases (e.g., Google Scholar, Sci-finder, PubMed, Springer, Elsevier, MDPI, Web of Science, etc.). The correlation between the Kaempheria species was evaluated via principal component analysis (PCA) and agglomerative hierarchical clustering (AHC), based on the main chemical classes of compounds. Results: Approximately 141 chemical constituents have been isolated and reported from Kaempferia species, such as isopimarane, abietane, labdane and clerodane diterpenoids, flavonoids, phenolic acids, phenyl-heptanoids, curcuminoids, tetrahydropyrano-phenolic, and steroids. A probable biosynthesis pathway for the isopimaradiene skeleton is illustrated. In addition, 15 main documented components of volatile oils of Kaempheria were summarized. Biological activities including anticancer, anti-inflammatory, antimicrobial, anticholinesterase, antioxidant, anti-obesity-induced dermatopathy, wound healing, neuroprotective, anti-allergenic, and anti-nociceptive were demonstrated. Conclusions: Up to date, significant advances in phytochemical and pharmacological studies of different Kaempheria species have been witnessed. So, the traditional uses of these plants have been clarified via modern in vitro and in vivo biological studies. In addition, these traditional uses and reported biological results could be correlated via the chemical characterization of these plants. All these data will support the biologists in the elucidation of the biological mechanisms of these plants.

“…Meanwhile, the roots of KGL are commonly used as flavoring agent in foods and spices because its taste is spicy and aromatic. In spite of these valuable properties, comparatively little is known about KGL and it is unutilized (Li et al 2017). Recently, flavonoids have received increasing attention because they exhibit many kinds of biological activities, such as antitumor (Shao et al 2005), antivirus (Evers et al 2005), anti-oxidation (Han et al 2009), antidiabetic (Li et al 2014) and strengthening the immune system (Deng et al 2011).…”

Ultrasonication assisted extraction (UAE) was employed to extract total flavonoids (TF) from Kaempferia galanga L. (KGL) roots. Single-factor experiments were performed to evaluate the effects of the process parameters (solvent-to-material ratio, ethanol concentration, extraction time, ultrasonic power, and extraction temperature) on the TF yield and the response surface methodology (RSM) was used to optimize the extraction parameters. The optimum conditions to obtain the maximum TF yield were solvent-to-material ratio, 25; ethanol concentration, 62%; extraction time, 27.0 min; extraction temperature, 50℃ and ultrasonic power, 225 W. The yield of TF under these conditions reached 3.22 ± 0.12 mg/g of dry root. The analysis of variance and validation test indicated that the proposed method is useful and reliable. The antioxidant capacities of TF of KGL was determined by DPPH· and ABTS+· methods, which revealed that it has good antioxidant activity in both systems.

“…In addition, fumigant toxicity (LC 50 = 1.5 mg/L air) of the essential oil against the booklouse also was observed ( Liu et al, 2014 ). The essential oil as well as 34 and 38 showed nematicidal activity against the cereal cyst nematode with LC 50 value of 91.78, 83.04 and 100.60 μg/ml, respectively, while borneol and 1, 8-cineole only showed slight nematicidal toxicity (LC 50 = 734.89 and 921.21 μg/ml, respectively) ( Li et al, 2017b ).…”

K. galanga is an aromatic medicinal herb. It is locally to India and distributed in China, Myanmar, Indonesia, Malaysia, and Thailand. K. galanga is a Traditional Chinese Herb Medicine (TCHM), which has been applied to treat cold, dry cough, toothaches, rheumatism, hypertension and so on. In addition, it has been used widely as spices since its highly aromas. The aim of this review is to compile and update the current progresses of ethnomedicinal uses, phytochemistry, pharmacology and toxicology of K. galanga. All the data on K. galanga were based on different classical literary works, multiple electronic databases including SciFinder, Web of Science, PubMed, etc. The results showed that ninety-seven compounds have been identified from rhizome of K. galanga, including terpenoids, phenolics, cyclic dipeptides, flavonoids, diarylheptanoids, fatty acids and esters. Modern pharmacology studies revealed that extracts or secondary metabolites of the herb possessed anti-inflammatory, anti-oxidant, anti-tumorous, anti-bacterial, and anti-angiogenesis effects, which were closely related to its abundant ethnomedicinal uses. In conclusion, although previous research works have provided various information of K. galanga, more in-depth studies are still necessary to systemically evaluate phytochemistry, pharmacological activities, toxicity and quality control of this herb.
