Ginger (Zingiber officinale Rosc; Zingiberaceae family) is an herb commonly used as a spice and remedy for a broad spectrum of diseases. The essential oil extracted from ginger is an effective antioxidant, anti-inflammatory, and antifungal agent. The present study has investigated the variations in yield and chemical composition of essential oils of two cultivars (Chinese and Thailand) of ginger locally available in Pakistan. Two different drying pretreatments were employed to observe the changes in compositional variations of the essential oils of ginger. The essential oil extracted from fresh, oven-dried, and sun-dried samples of two different cultivars of ginger was analyzed using gas chromatography-mass spectrometry (GC-MS). The essential oil yield was found to be highest for the sun-dried sample of each variety. The major compounds (>4%) overall in the essential oil of fresh, oven-dried, and sun-dried ginger samples from Thailand origin were camphene, 3-carene, o-cymene, caryophyllene, α-curcumene, sabinol trans, citral, and santalol. Major compounds overall in the essential oil of fresh, oven-dried, and sun-dried ginger samples of Chinese origin were α-pinene, Camphene, limonene, longicyclene, copaene, longifolene, β-sesquiphellandrene, alloaromadendrene, γ-muurolene, α-curcumene, α-farnesene, and citral. The inter-varietal variations and pretreatment methods considerably affected yield and chemical composition. Cluster analysis was performed to validate the results further. Significantly varying compounds responsible for the significant variation among varieties and treatments of the ginger were identifies by using the heat map. There was clear differentiation among Chinese and Thailand varieties due to the variation in the concentrations of the volatile compounds. The results obtained can be helpful for the ginger growers and end users to choose the ginger variety and the way of use that is more beneficial.

“…An ethanol extract of M. malabathricum was also reported to have a MIC of 60 mg/ In most cases, the antimicrobial activity of medicinal plants was associated with their essential oil content [109,110]. Essential oils could be isolated using solvents such as ethanol [111] and methanol [112]. Therefore, the antimicrobial activities of the methanol extracts of the studied herbaceous plants might be derived from their essential oil content.…”

Land restoration is expected to enhance the supply of valuable ecosystem resources such as herbaceous bushes and weeds. This study aimed to determine the primary phytochemical constituents and bioactivities of methanol extracts from eight bushes and weeds collected from a restored post-mining landscape in South Kalimantan, Indonesia. Qualitative phytochemical analysis showed the presence of phenolic compounds, flavonoids, tannins, alkaloids, steroids, terpenoids and saponins in the methanol extracts of herbaceous plants. Their antioxidant activity was measured by using the 2,2-diphenyl-1-picryl-hydrazyl-hydrate assay. Their superoxide dismutase (SOD) activity was also measured. In addition, selected plant extracts were screened against the common human pathogens Staphylococcus aureus and Candida albicans. Phytochemical analysis showed that the methanol extracts contained all the bioactive compounds examined in this study except the one from Lycopodium cernuum, which lacked flavonoids and alkaloids. Further investigation revealed that all methanol extracts except the one from L. cernuum had promising antioxidant potential. The methanol extracts from Chromolaena odorata (stem), Trema micrantha, Melastoma malabathricum (flower and leaf) and Thypa angustifolia exhibited effective antibacterial activity. In addition, the methanol extracts from M. malabathricum (flower and leaf), T. micrantha, Scleria sumatrensis and Breynia cernua (leaf) exhibited effective antifungal activity. M. malabathricum (flower and leaf) has the greatest potential as a herbaceous plant since its methanol extract exhibits the most potent antioxidant, antibacterial and antifungal activities.

“…The plant is indigenous to warm tropical climates, particularly south eastern Asia. As a result of its pungency, aroma, nutrients and pharmacological activities and neglible side effects, it is now widely cultivated in many countries like India, Nigeria, Jamaica, Mexico, Greece, and Hawaii (Kiyama, 2020;Mohammed et al, 2022). The plant is widely used for variety of purposes.…”

Constipation is a common gastrointestinal disorder that affects people of different ages, but is more common in elderly females. The disease has negative impact on the quality of life and can cause many complications including faecal incontinence, anal fissures, bowel perforation and bloating if not treated. This research was carried out to investigate the effect of n-hexane extract of Zingiber officinale (ginger oil [GO]) on loperamide-induced constipation in Wistar rats. Twenty four (24) Wistar rats of both sexes were randomly separated into 6 groups (n=4). Group 1 (control) received normal saline (NS) only, while groups 2 to 6 were treated with 4 mg/Kg/day loperamide. After 1 hour of loperamide treatment, Groups 2, 3, 4, 5 and 6 received 1 mL/kg/day NS, 100 mg/Kg/day GO (LDGO), 200 mg/Kg/day GO (MDGO), 400 mg/Kg/day GO (HDGO), and the standard drug bisacodyl (5 mg/Kg/day). All drugs were administered orally. Daily faecal pellet counts, weight and water content were measured. Intestinal transit of charcoal meal was determined while colon samples were harvested at sacrifice, homogenized and centrifuged. The supernatant was used to assay for SOD and MDA. Colonic tissue was also analyzed for histological changes. The result showed that, compared to control, loperamide significantly decreased the number, weight and water content of faeces while GO significantly increased all these parameters in a dose dependent manner. Ginger oil also significantly increased intestinal transit ratio and the activity of SOD but reduced MDA relative to loperamide + NS. Furthermore, histomorphology revealed that GO treatment increased the number of mucus secreting goblet cells and the thickness of the colon mucosa relative to Loperamide + NS treated rats. In conclusion, ginger oil ameliorated loperamide-induced constipation by increasing the faecal count, faecal water content and intestinal motility. Furthermore, GO showed protective effect on the colon through antioxidant activity while reducing lipid peroxidation and by also increasing the number of goblet cells and the mucosa thickness of the colon.
