“…Orthosiphon stamineus contains phenolic compounds and flavonoids that serve as antioxidants, antimicrobials, and anti-proliferative (Ashraf et al 2020) and treat glucose intolerance in pregnancy (Lokman et al 2019). Ocimum basilicum contains phenolic compounds, is rich in antioxidants, has an inhibitory effect on bacterial growth (Gürgan and Adiloğlu 2021), and is used as antidiabetic (Othman et al 2021).…”

Abstract. Supiandi MI, Ege B, Julung H, Zubaidah S, Mahanal S. 2021. Ethnobotany of traditional medicine in Dayak Jangkang Tribe, Sanggau District, West Kalimantan, Indonesia. Biodiversitas 22: 5417-5424. The Dayak Jangkang tribe has local knowledge about the use of medicinal plants that have been going on for a long time. Unfortunately, the local knowledge of the Dayak Jangkang tribe is currently threatened to disappear because it is delivered orally; there are no written documents and a wasteful lifestyle. The study aimed to document traditional medicinal plants that are utilized by the Dayak Jangkang tribe. The research approach used was qualitative descriptive using the field survey. The study interviewed three informants categories, i.e., the main informant (one customary chairman), key informant (one village head), and recommended informant (eight people who were knowledgeable about medicinal plants). The data were obtained through in-depth interviews and participatory observations. Data analysis used qualitative descriptive. The study got 40 plants that are used for traditional medicine with Zingiberaceae as the most used family. The parts of plants used by the Dayak Jangkang tribe for treatments were roots, bulbs, rhizomes, stems, bark, banana hump, fruit, fruit skins, leaves, fruit, and seeds. The mode of preparation is still considered simple.

“…However, a study on antibacterial activities of different plant extracts showed that E. coli was susceptible to herbal extracts [23]. Our previous results with another medicinal aromatic plant basil revealed a higher antibacterial activity against Gram-positive bacteria [12,13]. Other studies also showed that thyme extract was highly effective on a Gram-positive bacterium Clavibacter michiganensis subsp.…”

“…The soil characteristics were as follows: The pH of the soil was 6.45, the content of available P2O5 was 36.2 mg/kg and exchangeable K2O 225.18 mg/kg. Moreover, the organic matter concentration was 1.91% [12,14]. No fertilizers and pesticides were used during the experiment.…”

“…The secondary metabolites are also dependent on the nutrient element contents. The nutrient change may considerably affect the antimicrobial activities of medicinal aromatic plants [12]. To the best of our knowledge, there is lack of information on the correlation of nutrient content and microbial inhibitory effect of Thymus vulgaris L. In order to sustain more conscious cultivation of plants with high medicinal and economical importance, information on medicinal aspects of such plants and their cultivation should be gathered and integrated.…”

The present study aimed to examine the correlation of plant nutrient elements with the antibacterial activity of methanol extract of Thymus vulgaris L. grown on soil from the experimental field without application of fertilizers or pesticides on two Gram-positive and two Gram-negative bacteria. The extract of thyme was obtained by maceration of aerial parts of the plant using methanol as the solvent. The contents of macro (P, K, Ca, and Mg) and micro (Fe, Cu, Zn, Mn, and B) nutrients were detected by ICP-OES. The results showed that the macro nutrients were compatible with herbaceous perennial plants, while Fe, Mn and B micro nutrients were high. The methanol extract was significantly effective on inhibiting P. aeruginosa, S. aureus and E. faecalis, while did not inhibit E. coli. The correlation of K and Mg was significantly positive with the growth inhibition of P. aeruginosa suggesting that higher K and Mg contents of the plant would result in higher antibacterial activity against P. aeruginosa, most probably up to a point. On the other hand, significant positive correlation of B was found with the inhibition of both Gram-positive bacteria. In addition, the positive correlation of Ca with the growth inhibition of S. aureus was highly significant. The importance of nutrient contents in medicinal aromatic plants such as thyme was shown with this study. The results therefore imply the conscious and sustainable agriculture of medicinal aromatic plants is crucial for the antibacterial activity of thyme.

“…In other countries, this plant has been used against earache problems, kidney disorders, diarrhea, coughs, colds, headaches, insect bites, nerve pains, cardiovascular diseases, sinusitis, menstrual cramps, migraines, fevers, and anxiety [ 24 , 25 , 26 ]. Several articles have investigated the biological properties of O. basilicum , including antioxidant [ 27 , 28 , 29 ], antimicrobial [ 30 , 31 , 32 , 33 , 34 ], anticancer [ 35 , 36 ], immunomodulatory [ 37 ], insecticide [ 38 ], anti-thrombotic [ 39 ] antiplatelet [ 40 ], anti-inflammatory [ 41 ], anti-hyperlipidemic [ 40 ], and anticonvulsant [ 38 , 42 ] effects. However, other pharmacological properties such as dermatoprotective effects have not been investigated.…”

This study aimed to determine the chemical composition of the essential oils (EOs) of Ocimum basilicum L., as well as to evaluate the antibacterial, antidiabetic, dermatoprotective, and anti-inflammatory properties, and the EOs and aqueous extracts of O. basilicum. The antibacterial activity was evaluated against bacterial strains, Gram-positive and Gram-negative, using the well diffusion and microdilution methods, whereas the antidiabetic activity was assessed in vitro using two enzymes involved in carbohydrate digestion, α-amylase and α-glucosidase. On the other hand, the dermatoprotective and anti-inflammatory activities were studied by testing tyrosinase and lipoxygenase inhibition activity, respectively. The results showed that the chemical composition of O. basilicum EO (OBEO) is dominated by methyl chavicol (86%) and trans-anethol (8%). OBEO exhibited significant antibacterial effects against Gram-negative and Gram-positive strains, demonstrated by considerable diameters of the inhibition zones and lower MIC and MBC values. In addition, OBEO exhibited significant inhibition of α-amylase (IC50 = 50.51 ± 0.32 μg/mL) and α-glucosidase (IC50 = 39.84 ± 1.2 μg/mL). Concerning the anti-inflammatory activity, OBEO significantly inhibited lipoxygenase activity (IC50 = 18.28 ± 0.03 μg/mL) compared to the aqueous extract (IC50 = 24.8 ± 0.01 μg/mL). Moreover, tyrosinase was considerably inhibited by OBEO (IC50 = 68.58 ± 0.03 μg/mL) compared to the aqueous extract (IC50 = 118.37 ± 0.05 μg/mL). The toxicological investigations revealed the safety of O. basilicum in acute and chronic toxicity. The finding of in silico analysis showed that methyl chavicol and trans-anethole (main compounds of OBEO) validate the pharmacokinetics of these compounds and decipher some antibacterial targets.
