Background: Suaeda vermiculata, a halophyte found in central Saudi Arabia, used as a remedy for jaundice, liver diseases, and viral infection. Study aim: Chemical identification and biological evaluation for the n-hexane extract of S. vermiculata. Methods: An assay of the antimicrobial and antioxidant potentials and contents of the volatile oil and n-hexane extract of the plant{\textquoteright}s aerial parts were analyzed through GC-MS analysis. Results: A total of 24 constituents representing 73.74 \% of the n-hexane extract were identified wherein bornyl acetate, γ-elemene, and phytol were major ratio. The n-hexane extract inhibited DPPH-radicals inhibitions at 27\% efficiency at 10 mg/ml concentration which was lower than the volatile oil DPPH-reactivity. The antimicrobial activity of n-hexane extract was relatively weaker than the volatile oil, except against Candida albicans that showed IZD values of 19 mm with MIC value at 5.2 mg/ml for the volatile oil while IZD value of 26 mm and MIC at 4.7 mg/ml was observed for the n-hexane extract. Conclusion: Despite high extractive value, the n-hexane as a solvent is not recommended for extraction as the oxygenated-terpenic components, considered responsible for antioxidant and antimicrobial activities were not fully extracted. The n-hexane extract which showed potent inhibition of C. albicans can be a source for further investigation for bioactivities of its constituents.

Introduction: Zanthoxylum rhetsa is a tree found in northern Thailand. It has been used as a traditional herb with medicinal properties. However, the comparison of composition in volatile oil from fresh and dried fruit is still not fully investigated. In study, we evaluated the constituents in oil from fruits of Z. rhetsa and evaluated the cytotoxicity in non-small lung cancer cells. Methods: The hydro distillation was applied to afford the oil. The obtained oil was analyzed by GC-MS and evaluated the cytotoxicity and apoptosis in non-small lung cells by using MTT method and flow cytometry respectively. Results: Fresh and dried fruits provided a higher yield of volatile oil by approximately 10\% and 20\% respectively, compared to other studies. Twenty-eight compounds were identified and the major components of fresh and dried fruits were not distinctly different. The major component, \α-limonene, was found in dried fruits from Phayao, southern Nan and Chiang Rai province. A high content of \β-phellandrene was found in dried fruits from northern Nan province and the (+)-sabinene was found in high content of fresh fruits from southern Nan, Phayao and Chaing Rai province. Furthermore, the cytotoxicity tests displayed that all of oil products were active against lung cancer cells. Among the components investigated, fresh and dried fruits from southern Nan province showed to be the most potent (EC50 = 1.91 \± 0.53, 1.79 \± 0.43 \μL/mL, respectively). Conclusion: Volatile oil of Z. rhetsa exhibited a strong cytotoxic properties against cytotoxic may be potentially used as natural anticancer agents.

The Rhizomes of Nardostachys jatamansi D.C (Family Valerianceae) were collected from Haridwar, Uttarakhand. Aim: To identify the various volatile constituents of Nardostachys jatamansi D. C. Rhizomes and evaluation of antimicrobial activity. Method: The essential oil was collected by hydro distillation and analyzed by Gas Chromatography (GC) and Gas Chromatography-Mass Spectroscopy (GC- MS). Volatile oil constituents, antimicrobial potential of Nardostachys jatamansi D. C. Rhizomes have been studied using different concentrations of the volatile oil against some micro-organisms. Results: A total of 10 compounds were identified from their fragmentation pattern. The Identified compounds were Calarene (20.4\%), Vardiflorene (12.3\%), \α- Panasinsen (9.7\%), \α- Santalene (4.6\%), \γ-Himachelene (17.1\%), Jatamansone (7\%), Ionol 4 (9.9\%), 2,2,7,7- Tetramethyl tricyclo[6,2,1,0 (1,6)] undec-4-ene 3-one (1.7\%), Epiglobulol (1.9\%) and Resibufogenin (8.4\%). Among them major constituents characterized was Calarene (20.4 \%) and followed by \γ-Himachelene (17.1\%) and Vardiflorene (12.3 \%). The volatile oil showed significant activity against all tested microorganisms. The maximum antibacterial activity was shown with 1\%v/v of volatile oil on Staphylococcus aureus (12.8 mm) followed by Escherichia coli (12.4 mm), whereas maximum anti-fungal activity was shown by 1\% v/v of volatile oil on Candida albicans (12.3 mm) followed by Aspergillus niger (11.9 mm). Conclusion: All identified constituents showed antibacterial activity and antifungal activity. Thus, the constituents should be further identified and analyzed by other spectrosopical techniques.
