“…A methanol extract of rhizomes of K. galanga exhibited a concentration-dependent antioxidant activity in DPPH, ABTS, and nitric oxide (NO) radical scavenging assays [20]. Moreover, the essential oil extracts of conventionally propagated and in vitro propagated K. galanga had significant DPPH radical scavenging activity [35]. As well, the ethanol extract of K. rotunda exhibited antioxidant activity in a DPPH assay with IC 50 (67.95 μg mL −1 ) [30].…”

“…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]. The volatile oils of Kaempheria species were reported to have numerous biological activities such as anti-microbial [83], antioxidant [35], nutraceutical [83], nematicidal toxicity [82], and larvicide activities [29]. Table 4 summarized the main components ( 142–157 ) of the reported volatile oils of Kaempheria species.…”

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.

“…The essential oils of B. rotunda are directly used in the preparation of Ayurvedic drugs, cosmetics, perfumery, and spices in India [49]. Similarly, in Thailand's primary health care system, B. rotunda rhizome is recommended for the treatment of abscesses, leukoplakia, leukorrhea, and stomachache [50].…”

Ethnomedicinal Uses of Some Common Malaysian Medicinal Plants

Natural Drugs From Plants

View full text Add to dashboard Cite

Historically, natural products have always been a rich source of novel pharmacological leads, thus, making the ethnobotanical and ethnopharmacological knowledge an important and major asset of the medicinal plant-based drug discovery in providing hints for effective and safe chemotherapeutic compounds. Such knowledge, however, requires a thorough review and documentation of the ethnomedicinal and indigenous uses of local plants of every part of the world. Malaysia is a global hub for natural products which contributes to its GDP. Malaysia is also one of the 12 most diverse Megabiodiversity countries. Its rainforest is ranked 4th on the list of biodiversity hotspots in Asia after India, China, and Indonesia and is also acknowledged as the world’s oldest rainforest. Natural products are relevant to both Malaysian health care and agriculture which are parts of the national key economic areas (NKEA) under the Government’s Economic Transformation Plan as well as parts of the United Nations’ 17 Sustainable Development Goals (SDGs). Though the quality, efficacy, and safety of herbal products require global and international standardization, herbal products should be made accessible to low-income and rural communities across the globe. The proper documentation of the ethnopharmacological important plants in addition to their preservation and cultivation would enhance the sustainable use of the various indigenous plants. This work is unique in the sense that it is meant to review some of the most important high-value herbal products in Malaysia. Though it covers only a few representatives of Malaysian medicinal plants.

Synthesis of Rice Husk Mesoporous Silica as pH Responsive Release Material

The synthesis of mesoporous silica as a delivery agent for the ethyl para-methoxycinnamate has been carried out. The study aims to determine the process of mesoporous silica synthesis from sodium silicate from the smelting of rice husk ash, determine the adsorption capacity of mesoporous silica in the ethyl para-methoxycinnamate and the pH responsive release of ethyl para-methoxycinnamate with mesoporous silica as a delivery agent in simulated intestinal and gastric fluids. It was found that mesoporous silica can be synthesized from rice husk ash with a 30% tartaric acid template. Characterization of mesoporous silica using FTIR spectroscopy showed the presence of silanol (Si-OH) and siloxane (Si-O-Si) functional groups. Mesoporous silica from rice husk ash is able as adsorbent for the ethyl para-methoxycinnamate with the adsorption capacity of 8.26 mg/g. The release test of gastric simulation fluid (pH 1.2) showed that the ethyl-para-methoxycinnamate was released from silica for a period of 12 hours. In the intestinal simulation fluid (pH 7.4), the release of the ethyl para-methoxycinnamate occurred slowly at the first hour, then gradually increased at 5 hour up to 12 hour.
