Gen info
- Stephania is a genus of flowering herbaceous perennial vines in the family Menispermaceae.
- Etymology: The genus name Stephania derives from Greek, meaning "a crown" , referring to the anthers arranged in a crown-like pattern. The specific epithet refers to Japan, place of original collection, hence, japonica.

Malabuta is a woody smooth vine. Leaves are oval or sub-rounded oval in shape, 6 to 15 centimeters in length, and 4 to 12 centimeters in width, with obtuse and nearly retuse apex and rounded base, and smooth on both surfaces, with long petioles, 4 to 12 centimeters long. Inflorescences are in umbels on peduncles 3 to 4 centimeters in length. Male and female flowers are small, and pale yellow. Fruit is red, small, rounded but flattened, about 8 millimeters long and 6 millimeters wide.

- Native to the Philippines.
- In thickets and forests at low and medium altitudes in the Batan Islands; in Cagayan, Ilocos Norte, Bontoc, Lepanto, Benguet, Batangas, Rizal, and Laguna Provinces in Luzon; in Camiguin de Misamis.

Antioxidant / Analgesic / Cytotoxicity:
A crude methanolic extract exhibited moderate antioxidant activity in the DPPH radical scavenging and NO scavenging assays. The extract displayed analgesic activity with significant reduction in acetic acid writhing in mice. In Brine Shrimp lethality assay, it showed significant toxicity to Brine Shrimp nauplii. (1)
Diuretic Activity: Study of Stephania japonica roots showed diuretic activity, with significant increase of urinary output; the effect was much less than that of furosemide. (2)
Multidrug-Resistance Modulator: Alkaloidal extract of vines of Stephania japonica showed multidrug-resistance-reversing activity. Two known besbenzylisoquinoline alkaloids, isotrilobine and trilobine, were isolated. Trilobine showed to be as active as verapamil in reversing doxorubicin resistance in human breast cancer cells. (5)
Hasubanonine: Study has isolated an alkaloid, hasubanonine, which was tested against opiate-withdrawal. The compound also worked against multi-drug resistance.
Anti-Inflammatory / Antioxidant / Anti-Diarrheal: Plant showed significant anti-inflammatory effect on all phases of carrageenan-induced inflammation. The DPPH radical scavenging effect was 33.57 µg/mL compared to 15.57µg/ml for ascorbic acid. An anti-diarrheal effect in a castor oil-induced diarrheal model showed a reduction of total number of feces. (9)
Stephabenine: Study of fresh fruits yielded a hasubanan ester-ketal alkaloid, stephabenine. (11)
Diuretic Activity: In a study of comparative diuretic potential of methanolic extracts of C. pareira, Cyclea peltata, and Stephania japonica, all three demonstrated dose-dependent diuretic effects., with C. peltata exhibiting the most significant activity. (12)
Antioxidant / Analgesic / Leaves: Study evaluated antioxidant (DPPH, reducing power assay, Fe ion chelating ability, total phenolic content) and analgesic (acetic acid-induced writhing model of pain in mice) potential of ethanolic extract of leaves of S. japonica. Results showed moderate antioxidant and potent analgesic activity which increased with concentration. Activity may be due to the presence of phytochemicals like tannins, flavonoids, phenolics, and others. (14)
Antinociceptive / Leaves: The antinociceptive effect of a methanolic extract of S. japonica leaves was investigated using both heat- and chemical-induced nociceptive models such as hot plate, tail immersion, acetic-acid induced writhing, formalin and glutamate tests. Morphine and diclofenac were used as reference drugs. Results strongly support the antinociceptive activity of leaves and rationalize its traditional use in the treatment of various painful conditions. (15)
• CNS Depressant Activity / Bark: Study evaluated a methanolic extract of Stephania japonica bark in Swiss albino mice model. Evaluation of CNS activity by open field method and hold board test showed significant (p<0.001) dose dependent reduction of peripheral locomotion, central locomotion and leaning in the open field test and reduction of head dipping and head poking in the hold board test. (18)
• Antioxidant / Analgesic / Leaves: Study of ethanolic extract of leaves showed moderate antioxidant (DPPH, reducing power assay, Fe++ ion chelating ability and total phenolic content) and potent analgesic (acetic acid-induced writhing in mice) activity. Activities increased with concentrations and was attributed to the presence of phytochemicals like tannins, flavonoids, phenolics, etc. (19)
• Antimalarial / Leaves: Study evaluated the antimalarial activity of a crude aqueous extract of Stephania japonica leaves using chloroquine-sensitive Plasmodium falcifarum in mice. Results showed promising antiplasmodial activity as evidenced by dose dependent reduction in parasite density and percentage of parasitemia. The antimalarial activity was attributed to the presence of alkaloids. (20)
• Antidiabetic / Antihyperlipidemic / Leaves: Study investigated the antidiabetic and antihyperlipidemic activities of a methanolic leaf extract of S. japonica alone and with metformin in alloxan induced diabetic rats. The leaf extract and combination therapy reduced BG, TC, TG, LDL-C and increased HDL significantly (p<0.001). The LE also decreased LVH caused by alloxan and increased BW. (21)
• Antioxidant-Mediated Neuroprotective / Leaves: Study evaluated the antioxidant, neuroprotective and possible anxiolytic-like activity of a methanol leaf extract of S. japonica. The methanol LE exhibited antioxidant and anti-inflammatory activities. It also potentiated the action of diazepam and antagonized the effect of flumazenil suggesting a possible GABAergic, DZP-agonistic anxiolytic-like action in experimental animals. Study suggests a potential good source of neuroprotective phytochemicals. (22)
• Neuroprotective / Amelioration of Scopolamine-Induced Memory Impairment / Antioxidant: Alzheimer's disease is a progressive neurological disorder characterized by loss of memory and cognition. Study evaluated the anticholinesterase and antioxidant activities of crude methanol extract of S. japonica and fractions. The chloroform extract showed strong inhibition of acetylcholinesterase and butyryl-cholinesterase enzymes with IC50s of 40.06 and 18.78 µg/mL, respectively. The chloroform fraction showed potent antioxidant activity and inhibited peroxidation of brain lipid in vitro. There was significant association of anticholinesterase and antioxidant activity with alkaloid and phenolic contents. In mice, the chloroform fraction restored impaired learning and memory induced by scopolamine evidenced by significant decrease in latency time and increase in quadrant time in probe trial in Morris water maze task. The fraction significantly reduced cholinesterase activity and oxidative stress in mice and may have potential for the treatment and prevention of AD. (26)
• Antidiabetic / Leaves: Study of acetone and ethanol leaf extracts of S. japonica yielded alkaloids, carbohydrates, steroids, flavonoids, resins, saponins, tannins and coumarins. Both leaf extracts significantly (p<0.05 to p<0.001) improved lipid profile parameters, blood glucose, and serum hepatic marker proteins in alloxan-induced diabetic mice. (see constituents above) (27)
• Antidepressant / Hypnotic-Sedative / Whole Plant: Study evaluated methanolic crude extracts of S. japonica whole plants for possible antidepressant and hypnotic-sedative effects. In acute toxicity testing, safety was determined up to a dose of 2000 mg/kg p.o. In antidepressant testing using forced swimming test and tail suspension test, the extract at doses of 100 and 200 mg/kg p.o. significantly (p<0.01 and p<0.05) inhibited immobility time in a dose-dependent manner, with 13.56-26.46 % inhibition indicating mild antidepressant activity compared to nortriptyline (60.4-64.6% inhibition.  Open field test and hole-board test showed significant dose-dependent (p<0.001, p<0.01 and p<0.05) and moderate sedative-hypnotic effects compared to diazepam. Results suggest mild antidepressant and moderate but short-term sedative-hypnotic activities. (28)
Larvicidal / Culex quinquefasciatus / Leaves: Study evaluated the effect of fresh leaves extracts of twelve plants against late 3rd instar larvae of Culex quinquefasciatus under laboratory conditions with doses of 5, 2.5, 1.5, 0.625, and 0.3125%. At 5% concentration of leaf extract, Stephania japonica and Lawsonia inermis were most toxic, both killing 100% larvae. S. japonica showed LC50 of 1.406. Results showed eco-friendly alternative potential for use as larvicide against larvae of Cx. quinquefasciatus. (29)
