Quantitative analysis of the Zingiber Officinale sample using subcritical water extraction (SWE) was developed employing High-Performance Liquid Chromatography (HPLC) to bolster the advancement of this innovative green extraction process. This research focuses on three principal ginger bioactive compounds: 6-gingerol, 6-shagoal, and 10-gingerol. Various stages were undertaken to establish the quantitative analysis method, encompassing the optimisation of HPLC operating conditions and the formulation of standard calibration curves, yielding individual compound equations. A robust correlation within the calibration curve was achieved, exhibiting an r² value of 0.9814 and an RSD of 5.00%. A simultaneous, swift, and dependable method was established with an injection time of 20 minutes and an 8-minute delay between injections, in contrast to the previous HPLC analysis requiring a 45-minute injection time for detecting and quantifying all components. Notably, no post-treatment was applied after the SWE process. This advancement allows for potential future online measurement of Zingiber Officinale bioactive compounds extracted using subcritical water extraction through this technology.

Recently many investigators have initiated searches for immunomodulating substances from natural food sources. Ginger (Zingiber officinale Roscoe) has been used as a raw material in many traditional preparations since the ancient time. This study was performed to investigate the immunomodulative effects of Zingiber officinale Roscoe in mice, using ex vivo experiments. In order to elucidate the immunomodulative effects of Ginger, water extracts of the plant were orally administrated into mice, and isolated splenocytes and macrophages were used as experimental model. In order to identify its ex vivo effect six to seven week old Balb/c mice were fed ad libitum on a chow diet and water extracts of ginger were orally administrated every other day for two weeks at two different concentrations (50 and 500 mg/kg b.w.). After preparing the single cell suspension, the proliferation of splenocytes was determined by MTT assay. The result of ex vivo study showed that the highest proliferation of splenocytes and macrophage activatation was seen in the mice orally administrated at the concentration of 500 mg/kg b. w. of ginger water extracts. In conclusion, this study suggests that ginger extracts nay enhance the immune function by regulating the splenocyte proliferation and cytokine prodution capacity by activated macrophages in mice.

Ginger (Zingiber officinale) belonging to the family Zingiberaceae is a perennial herb. It is widely distributed in tropical Asia. In India, it is cultivated mainly in Kerala, Andhia Pradesh, Uttar Pradesh, West Bengal and Maharashtra. It is one of the most common spices, which is in use since centuries for its versatile medicinal actions like antiemetic, stomachic, expectorant, anti-inflammatory, aphrodisiac etc in traditional system of medicine (Unani, Ayurveda, and Chinese medicine). It is useful for the treatment of various gastrointestinal, pulmonary, cardiovascular and sexual disorders. The phytochemical study of ginger showed the presence of many volatile oils and oleo-resins like gingerol, zinger one, zingiberol etc. Numerous experimental and clinical trials have proven ginger for its range of therapeutic activities such as antibacterial, antidiabetic, antiemetic, hypolipidaemic, hepatoprotective etc properties. The present article aims to explore traditional Unani and pharmacological activities of this herb reported till date.

The antioxidative compounds and antioxidant contents of ginger (Zingiber officinale) rhizomes were determined. Substances reextracted using ethyl acetate from crude methanol extract of fresh ginger rhizome were separated through thin layer chromatography. Ten phenolic antioxidative bands were visualized through color reactions using ferric chloride-potassium ferricyanide and 1,1-diphenyl-2-picrylbydrazyl (DPPH). The antioxidative compounds were purified through preparative TLC and high performance liquid chromatography (HPLC), among which, five antioxidants were identified as 4-, 6-, 8-. and 10-gingerols and 6-shogaol on the basis of their molecular weights determined through LC-MS. As shown in experiments using DPPH free radicals, 6-Gingerol and PT4-HP8 (unknown) were revealed to be more efficient than BHT (butylated hydroxy toluene). Contents of gingerols were determined through reverse phase HPLC. Total gingerol contents (sum of 6-,8-, and 10-gingerols) in rhizomes of different ginger varieties varied significantly. The HG55 (collected at Wanju district in Korea) and the HG52 (imported from Brazil) showed the highest gingerol contents.

Zingiber officinale buds from the rhizomes were used to produce in vitro shoots. These explants produced the largest number of multiple shoots, 9.8 shoots per explant, when were cultured on MS (Murashige and Skoog 1962) medium supplemented with 2.0 mg/L benzyladenine (BA) and 2.0 mg/L indole butyric acid (IBA). This medium was also found to be suitable for in vitro propagation of other Zingiberaceae species: Alpinia conchigera, Alpinia galanga, Curcuma domestica, C. zedoaria and Kaempferia galanga. Both C. domestica and C. zedoaria produced more multiple shoots when were cultured in the liquid proliferation medium, MS medium containing 2.0 mg/L BA and 2.0 mg/L IBA. To maintain the in vitro plantlets of Zingiberaceae species, they were required to subculture every four weeks. After executing proper acclimatization protocol, in vitro plantlets of Alpinia galanga, A. conchigera, Curcuma domestica, C. zedoaria, Kaempferia galanga and Zingiber officinale could be successfully planted in the field with high percentage of survival.
