Geographical Distributions

Curcuma zedoaria is probably native to north-eastern India. Distributed through cultivation to South and South-East Asia and probably throughout Malesia, China and Taiwan from where it easily escapes. Occasionally it is cultivated elsewhere (e.g. in Madagascar). [7]

Botanical Description

C. zedoaria is a member of Zingiberaceae family. [1] It is perennial herb, grows up to 1.2 m in height, has both vertical aerial stem or pseudostems and horizontal underground tuberous rootstock or rhizomes. [11][12]

Rhizome conical branched robust, greyish brown to brown outside and pale yellowish inside. [7]

Leaves erect, glabrous, elliptic-oblong to oblong-lanceolate, up to 81 cm long, 18 cm wide, green with purple hue along the midrib. [11][12] The leaf sheaths are 35-60 cm long while the blades are oblong to oblong-lance-shaped. They are 25-75 cm x 7-20 cm, green with a purple band along the midrib. [7]

The inflorescence is on a separate shoot, cylindrical, 10–20 cm long, 8–15 cm wide, arises from a leafless underground stem. The bracts are green, sometimes with a purple margin. The coma bracts are purple or dark pink. The yellowish-white petal is 3.5-4.5 cm long. Its labellum is 2-2.5 cm x 1.5-2 cm, yellowish-white with a darker yellow median band. The other stamen is longitudinally folded, yellowish-white and the anther is with long spurs. [7][11][12]

Flowers with yellowish-white corolla, 3.5–4.5 cm long; corolla tube 2 cm long; labellum bilobed, 2–2.5 cm long, 1.5–2 cm wide, yellowish white with dark yellow median band; staminode longitudinally folded, yellowish-white, anther with long spurs; ovary is villous. [7][11][12]

Capsules are ovoid, triangular and dehiscing irregularly. [11][12]

Petroleum ether of C. zedoaria tuber (2.5–0.01 mg/mL) inhibited the growth of Bacillus subtilis with inhibition zone (IZ) of 15 mm and minimum inhibitory concentration (MIC) of 0.02 mg/mL, Microsoccus luteus (IZ: 13 mm, MIC: 0.01 mg/mL), Proteus mirabilis (9 mm, MIC: 0.04 mg/mL), Klebsiella pneumonia (8 mm, MIC: 0.02 mg/mL) compared to gentamycin (10 µg) (B. subtilis: 27 mm, M. luteus: 20 mm, P. mirabilis: 21 mm, K. pneumonia: 18 mm) and tetracycline (B. subtilis: 21 mm, M. luteus: 29 mm, P. mirabilis: 17 mm, K. pneumonia: 30 mm) using agar-well diffusion assay. [52]

Petroleum ether of C. zedoaria tuber inhibited the growth of C. albicans with inhibition zone of 10 mm and MIC of 0.04 mg/mL,Aspergillus niger (8 mm, MIC: 0.15 mg/mL) while acetone extract inhibited C. albican (8 mm, MIC: 0.01 mg/mL), A. niger (8 mm, MIC: 0.01 mg/mL) compared to clotrimazole (8 mm) using agar-well diffusion assay. [52]

Essential oils (5 mL) in methanol (100 mL) of C. zedoaria rhizome inhibited the growth of Mycobacterium phlei (MIC: 1.2 mg/mL) with inhibition zone of 18 mm compared to oxacilin (MIC: 0.0001 mg/mL, inhibition zone: 20 mm). The extracts also inhibited the growth of S. aureus with inhibition zone of 12 mm compared to kanamycin (22 mm) using disc diffusion assay. [53]

Ethanol extract of C. zedoaria rhizome inhibited C. albicans and C. dubliniensis with MIC of 2.6 ± 0.9 mg/mL, C. glabrata (MIC: 6.25 ± 0 mg/mL), C. krusei (MIC: 8.33 ± 3.6 mg/mL), C. tropicalis ATCC 750 and ATCC 13803 (MIC: 2.60 ± 0.9 mg/mL) and C. tropicalis ATCC 66029 (MIC: 1.56 ± 0 mg/mL). Meanwhile, the growth of fungal was inhibited with minimum fungicidal concentration (MFC) at > 25 mg/mL against C. albicans, C. glabrata, C. krusei, C. tropicalis ATCC 750 and ATCC 13803 whileC. dubliniensis and C. tropicalis ATCC 66029 were inhibited at MFC of 25 ± 0 mg/mL compared to chlorhexidine using broth microdilution assay. [54]

The essential oil of C. zedoaria with high content of epicurzernone and curdione, proved to be most effective against Vibrio parahaemolyticus and least sensitive to E. coli. [55]

Ethanolic extract of eight medicinal plants including C. zedoaria was tested for their antibacterial activity against four gram positive strains (Bacillus subtilis, Staphylococcus aureus, Staphylococcus epidermidis and, Streptococcus pneumoniae) and six gram negative strains (Escherichia coli, Proteus vulgaris, Proteus mirabilis, Salmonella typhi para A, Salmonella typhi para B, and Shigella dysenteriae). Results obtained show that C. zedoaria exhibit a potent antibacterial activity. [56]

Hot ethanol extract of C. zedoaria was fund to exhibit antifungal activity against Trichophyton rubrum, Aspergillus niger, Saccharomyces cerevisiae and Epidermophyton floccosum at a concentration less than 10 mug/ml, A. fumigatus, Penicillium purpurogenum, Trignoposis variabilis, Microsporum gypseum, Sclerotium rolifsii, Geotricular candiade, Fusarium oxysporum and Helminthosporium oryzale at a concentration less than 25mug/ml, and Candida krusei and T. mentagrophytes at a concentration less than 50 mug/ml. [57]

C. zedoaria exhibits significant antifungal activity against a wide variety of human pathogenic fungi including those resistant to common antifungal amphotericin B and ketoconazole. [58]

Antiarthritic activity

Rats treated with petroleum ether and chloroform extracts of C. zedoaria roots showed significant recovery in behaviour and radiological changes from Freund’s Complete Adjuvant-induced monoarthritis in rats. Evidence that these extract could be useful in providing relief from arthritic conditions. [59]

Uterine muscular excitatory activity

Aqueous extract of C. zedoaria was seen to significantly increase the spike area, duration and number of bursts of action potentials of rat uterine smooth muscle in a dose-dependent manner. This effect was decreased by atropine and phentolamine but not verapamil, diphenhydramine and indomethacin. Thus the excitatory effect of aqueous extract of C. zedoaria on mice uterine muscles is associated with M-receptor and α-receptor. [60]

Anticancer activity

The essential oil extracted from C. zedoaria showed the capability of inhibiting growth of human promyelocytic leukaemia HL-60 cells via apoptosis. [55]

The polysaccharide fraction (CZ1-III) of C. zedoaria was found to have the ability to inhibit the growth of solid tumour (sarcoma 180 cells) in a dose dependent manner. It did not show any mutagenicity and clastogenic activity. This shows that CZ1-III was able to decrease tumour size and prevent chromosomal mutation in mice. [61]

Curcuminoids isolated from methanolic and aqueous extract of C. zedoaria rhizomeswas found to play a pivotal role in the antimutagenic activity against mutagens, either 2-amino-3-methylimidazo (4,5-f) quinoline (IQ) or 4-nitroquinoline-N-oxide (4-NQO), in dosages of 1-50 µg/plate that was assayed by using Salmonella typhimurium TA97, TA98, TA100, and TA102 strains. [62]

Toxicity

Embryotoxicity activity

Essential oil of C. zedoaria rhizome (40 µg/mL) was treated on Sprague Dawley’s embryos (gestation day (GD) of 9.5) for duration of 48 hours. The extract showed significant (p < 0.01) developmental toxicity with reduction of yolk sac diameter (3.10 ± 0.47 mm), crown-rump length (2.53 ± 0.37 mm) and head length (1.33 ± 0.22 mm) while decrease the somite number (9.33 ± 1.51) and total morphological score (17.63 ± 2.07) compared to N,N-dimethylformamide-treated control (yolk sac diameter: 5.22 ± 0.49 mm, crown-rump length: 3.89 ± 0.49 mm, head length: 2.01 ± 0.16 mm, somite number: 22.25 ± 1.83, total morphological score: 34.88 ± 1.25) using ex-vivo whole-embryo culture assay. [45]

Essential oil (200 mg/kg) of C. zedoaria rhizome administered orally to pregnant Sprague Dawley rats (age 10-12 weeks) from GD7 to GD17 significantly (p < 0.01) decrease number of live fetuses (7.6 ± 1.1), placental weight (0.305 ± 0.045 g), fetal weight (0.744 ± 0.072 g), crown-rump length (1.773 ± 0.063 cm) and head length (0.937 ± 0.059 cm) compared to corn oil-treated control group (number of live fetuses: 11.4 ± 1.5, placental weight: 0.379 ± 0.067 g, fetal weight: 0.955 ± 0.074 g, crown-rump length: 1.979 ± 0.086 cm, head length:1.048 ± 0.050 cm). [45]

Genotoxicity activity

Hydroalcoholic (50%) extract of C. zedoaria rhizome (39.06, 78.125 and 156.25 µg/mL) was treated on human lymphocytes for duration of four hours. The extract showed genotoxic activities with chromosomal aberrations (2.0, 2.5 and 6.5%, respectively) compared to Mitomycin C (0.3 µg/mL) (16.0% of chromosomal aberrations) using chromosomal aberration test.
