Buntot-tigre is a herbaceous perennial with
short stem and a rootstock that is very stout, branching and stoliniferous. Leaves are erect, fleshy, fibrous
and flat ( in other varieties cylindrical or concave above, rounded dorsally),
sub-erect, dagger-shaped, rigid, pale-green with transverse bands of dark
green, or dark-green with gray mottles, 0.4 to 1.5 meters long, 4 to 7 centimeters wide. Scape is erect, 30 to 80 centimeters long. Flowers are pale-colored,
numerous, in fascicles of 3 to 6, sweet-scented, 2.5 to 3 centimeters
long, with the perianth segments nearly twice as long as the tube. Fruit is sparingly produced, globose, about 8 millimeters in diameter. Seeds
are broadly ovoid and white, with horny albumen.
Note: Buntot-tigre (Sansevieria roxburghiana) is often confused with Tigre (Sansevieria trifasciata). Some compilations list them as synonyms.
- Cultivated in many parts
of the Philippines.
- Naturalized, occurring in thickets and hedges at low and medium
- Native of tropical Asia, now pantropic in cultivation.
- Contains an active constituent:
the alkaloid sansevierine.
- Phytochemical screening of leaves and rhizomes yielded carbohydrates, saponin, flavonoids, phenols, alkaloid, anthocyanin and ß-cyanin, glycosides, proteins, and phytosterols.
(see study below) (9)
- GC-MS analysis of methanol extract of leaves yielded 16 bioactive phytochemical compounds: diethyl phthalate (1), 6-methyl-1-octanol (2), 2-propyldecan-1-ol (3), 2(4H)-benzofuranone (4), 3,3-dimethylhexanal (5), diisobutyl phthalate (6), 6,10,14-trimethyl-2-pentadecanone (7), 2,5-dimethoxybenzhydrazide (8), 3,4-dimethoxybenzoic anhydride (9), 1,2-benzenedicarboxylic acid, bis(2-ethylhexl) ester (10), dodecanoic acid (11), palmitaldehyde, diallyl acetal (12), 1-butyl 2-(8-methylnonyl) phthalate (13), delta-undecalactone (14), methyl hexadecanoate (15), n-hexadecanoic acid (16). (see study below) (15)
- Study of carbon tetrachloride solube fraction of a methanol
fraction of whole plant yielded a homoisoflavonoid (cambodianol), and a triterpene (lupeol). (17)
- Emollient, purgative, tonic, febrifuge, cardiotonic, expectorant.
- Studies suggest antibacterial, antitumor, antidiabetic, antioxidant, cytotoxic properties.
Parts used a
Leaves, shoots, rootstocks.
- The roasted leaves used as an emollient.
- In India, rootstocks used for cough; tender roots and rhizome used as expectorant. Also used as febrifuge, tonic, purgative, and for bone setting.
In India, stem part of rhizome used for toothache. Rhizomes used for consumptive complaints, cough, common cold, and ear pain. (10) Leaves used to treat pimples and skin diseases. (12) Leaves used to treat asthma. (16) Juice boiled with coconut oil applied to ear ache.
- In Bangladesh, juice of tender shoots used in children to clear sticky phlegm from the throat; juice from young leaves applied topically to ear infections.
- In viral diseases associated with stringy nasal discharge, slightly warmed leaf juice is used as nasal drops, thrice in two hours. A paste is also applied over the body.
- In India, stem part of rhizome used to heal wounds in animals. (10)
- Fiber: The leaves are a source of a
strong white fiber use in the manufacture of bowstring, twine, cloth,
and paper. It is sometimes mixed with the local piña.
• Anticancer: Study of the methanol extract of Sansevieria roxburghiana in male Swiss albino mice transplanted with Ehrlich Ascites Carcinoma cell line showed significant dose-dependent anticancer activity. (3)
• Anticancer / Rhizome: Study of hydroalcoholic extract of SR for antitumor activity against EA carcinoma exhibited remarkable antitumor activity attributed to its augmentation of endogenous antioxidant mechanisms. (5)
• Antidiabetic / Antioxidant Modulation: Study of hydroalcoholic extract of SR rhizome in streptozotocin-induced diabetic rats demonstrated remarkable antidiabetic activity possibly through its modulation of endogenous antioxidant status. (7)
• Antimicrobial / Leaves and Rhizome: Study evaluated various solvent and aqueous extracts of leaves and rhizomes of S. roxburghiana against clinically significant bacterial and fungal strains. Methanol and acetone extracts of leaves and ethyl acetate extract of rhizomes showed significant antimicrobial activity against Gram negative and positive bacteria and fungal strains. The leaf extract showed better antimicrobial activity than rhizomes. (see constituents above) (9)
• Antibacterial / Rhizome: Study of ethanolic extracts of rhizome of S. roxburghiana showed antibacterial against gram negative bacteria such as Salmonella typhi, Pseudomonas fluorescens, P. aeruginosa, and E. coli. (10)
• Antibacterial / Leaves : Study investigated the antibacterial activity of pure fractions of leaves of Sansevieria roxburghiana. Two out of three fractions showed pronounced activity at 1 mg/ml against gram positive and gram negative bacteria responsible for various infections. (see constituents above) (15)
• Analgesic / Cytotoxic / Antioxidant : Study of evaluated crude methanolic extract of whole plant of S. roxburghiana for analgesic, cytotoxic, and antioxidant activities. Results showed analgesic activity by acetic acid induced writhing test in mice, cytotoxic activity by brine shrimp lethality bioassay, and antioxidant effect by DPPH free radical scavenging assay.

- Cultivated and wild-crafted.
