“…According to the statement of World Health Organization, the increase of the resistance to antibiotics arising in recent years is accepted as one of the most significant problem for human health [20] . In this regard, potential effects of plant extracts on microorganisms have been studied by many researchers [21] . Some studies reported the presence of antibacterial and antifungal activities of several types belonging to Thymbra species.…”

Plants and bioactive substances from plants were used as traditional medicine to treat diseases throughout history. Nowadays, treatment with plants still continues significantly in various cultures. According to the World Health Organization, approximately 65 % of the world population uses plants for treatment purposes [1] . There have been many studies related to the biological effects of plants. Therefore, extracts and essential oils obtained from plants have been used as anticancer agents in addition to antimicrobial, antiviral and antiparasitic effects. Thymbra sintenisii is thought as an important branch of Lamiaceae family [2][3][4] .Thymbra species are represented in the flora of Turkey by two types and 4 taxon, which are T. spicata L. (var. spicata, var. intricata P.H. Davis) and T. sintenisii Bornm. and Aznav. (subsp. sintenisii, subsp. isaurica P.H. Davis). The dried leaves of the plant, known as "white zahter" colloquially, are used in the form of a herbal tea in Anatolia and as an antiseptic against

“…H. favum rhizome essential oil rich in β-pinene, α-pinene, nerolidol, and α-terpineol was proven to exhibit antioxidant activity [14]. According to past research, essential oils from various Hedychium plants rich in α-pinene and β-pinene (e.g., H. coronarium, H. greenii, and H. forrestii) possess antioxidant activity [11,41,42]. β-Pinene demonstrated signifcant antioxidant activity in the DPPH assay [43].…”

Hedychium flavum is an edible, medicinal, and aromatic plant widely cultivated for its essential oil. So far, little studies have been done on its phytoconstituents and bioactivities. Hence, the research aimed to determine the chemical constituents of leaf essential oil (L-EO) and stem essential oil (S-EO) of H. flavum and first estimate their antibacterial, antioxidant, cytotoxic, and enzyme inhibitory activities. According to gas chromatography-flame ionization detector/mass spectrometer (GC-FID/MS) assay, L-EO was mainly composed of β-pinene (33.4%), α-pinene (10.4%), humulene (6.8%), β-caryophyllene (6.0%), eucalyptol (6.0%), caryophyllene oxide (5.5%), endo-borneol (3.8%), humulene epoxide II (3.7%), and D-limonene (3.2%). The predominant components of S-EO were β-pinene (17.2%), eucalyptol (9.7%), nerolidol (7.8%), α-phellandrene (6.7%), α-pinene (5.8%), β-caryophyllene (5.4%), terpinen-4-ol (4.5%), D-limonene (4.4%), p-cymene (3.7%), endo-borneol (3.5%), and α-terpineol (3.5%). For the bioactivities, L-EO and S-EO showed strong antibacterial activity against Escherichia coli, Enterococcus faecalis, and Bacillus subtilis with the minimum inhibitory concentration (MIC) of 9.77–625.00 µg/mL and the minimum bactericidal concentration (MBC) of 9.77–1250.00 µg/mL. Both L-EO and S-EO exhibited moderate antioxidant activity in the DPPH (14.52 ± 0.93 mg/mL and 4.73 ± 0.15 mg/mL, respectively) and ABTS (4.05 ± 0.75 mg/mL and 2.38 ± 0.14 mg/mL, respectively) free radical scavenging capacity. S-EO showed selective cytotoxicity on human leukemic K562 cell line (IC50 = 93.94 ± 0.91 µg/mL), which was nearly three times that of noncancer L929 cell line (IC50 = 294.49 ± 9.40 µg/mL). In enzyme inhibitory properties, L-EO exerted a potent inhibition on α-glucosidase (IC50 = 1.03 ± 0.02 mg/mL), and both essential oils had weak inhibition against cholinesterase and tyrosinase. Thus, H. flavum L-EO and S-EO possess antibacterial, antioxidant, cytotoxic, and enzyme inhibitory activities with potential for exploitation in the food, cosmetic, and pharmaceutical industries.

Antioxidant compounds play a significant role in preventing and scavenging free-radicals by reducing oxidative stress and providing protection to humans against degenerative diseases and infections. Obviously, antioxidant molecules of plant origin are pivotal to combat the oxidative harm in cells. Present work intended to evaluate the antioxidant capacity of the fruits of Spondias pinnata. Methanol extracts of the fruits at two stages of maturity were prepared and investigated by various antioxidants analyses such as total antioxidant activity, reducing power and radical scavenging assays (DPPH, nitric oxide and hydrogen peroxide). Its total phenol, flavonoid and tannin contents were also determined. Spondias pinnata fruit extracts exhibited effective antioxidant activity and its IC50 values of the unripe fruits were 65, 66, 72.23, 83.25, 66.75 ?g/ml and ripe fruits were 124.24, 92.50, 97.66, 144.10, 72.25 ?g/ml, for total antioxidant activity, reducing power, DPPH radical scavenging, nitric oxide radical scavenging and hydrogen peroxide scavenging assays respectively. The extracts, especially unripe fruit extract had good amounts of total phenolic and flavonoid contents which might contribute the antioxidant activities considerably. It is evident from the study that the fruits of S. pinnata possessed potent antioxidant activity and it can be considered as a good dietary choice among the underutilized fruits as well as common fruits. Therefore, wild mango may be a good choice of antioxidants of plant origin for dietary and pharmaceutical uses.
