Gen info
- Meiogyne is a genus of flowering plants in the family Annonaceae. It contains 38 species, native from southwestern India and Indochina to Australia, including Fiji and New Caledonia. The type species is Meiogyne virgata. (2)
- Etymology: The specific epithet virgata derives from Latin virgatus , meaning "twiggy, striped, wand-like".

Botany
• Shrub or tree up to 12.5(–15 m) tall; bark gray to brown-gray, smooth. Twigs puberulent, soon glabrate. Leaves chartaceous, elliptic, ovate, or sometimes oblong-elliptic, 9.8–22 by 4.5–9 cm, base broadly cuneate to rounded, apex acuminate, the acumen 7–15 mm long, pubescent along midrib on both surfaces but otherwise glabrate, secondary veins slightly arcuate, 7–15 per side, tertiary venation distinctly percurrent; petioles 5–9 mm long. Inflorescences axillary, 1-flowered, extended rachis absent, pedicels ca 3 mm long, with 2 small bracts; petals separating early in bud. Sepalsfree to minutely connate, broadly ovate, ca 5 mm long, acute to attenuate. Petals cream-coloured to pale brownish yellow, acute to obtuse; outer petals linear to linear-lanceolate, 13–17 by 2.5–3.5 mm, finely pubescent on outer surface; inner petals lanceolate, 9–10 by 3–3.5 mm, with a pink-red, purple, or brown corrugated patch on proximal 1/2 of inner surface. Stamens clavate, ca 1 mm long, anther connective apex truncate. Carpels 3–5, stigmas globose, ca 0.5 mm long. Fruit of up to 4 monocarps borne on a pedicel 3–5 mm long. Monocarps green, purplish, brown, or blackish yellow, oblongoid to ellipsoid, not torulose, 2.2–5.4 by 2.2–2.8 cm, gray- or brown-tomentose (hairs matted), apex rounded, sessile or rarely base contracted into a stipe up to 3 mm long; pericarp ca 3.5 mm thick, woody when dried. Seeds in two rows, 11–15 per monocarp, semicircular in lateral view, flattened, 15–20 by 10–11 mm, ring encircling seed raised as a ridge.

Distribution
- Native to the Philippines. (1) (3)
- In Bohol, Leyte, Luzon (Laguna, Sorsogon), Mindanao (Agusan del Norte, Davao del Sur, Surigao, Surigao del Norte), Palawan, Samar. In primary or secondary forests, 0-1300 m. (3)
- Also native to Borneo, Jawa, Malaya, Thailand, Vietnam. (1)

Constituents
- Phytochemical study on bark of M. virgata yielded nine known alkaloids: liriodenine 1, lanuginosine 2, asimilobine 3 and lysicamine 4; four aporphines, anonaine 5, N-methylanonaine 6, nornuciferine 7 and norushinsunine 8; and one azaanthracene alkaloid, cleistopholine 9. (4)
- Hydrodistillation and GC-FID/MS of leaves for EO yielded major compound of germacrene D (42.48%) for M. virgata. (see study below) (5)
- GC-FID and GC-MS study of EO from stems yielded α-humulene, bicyclogermacrene, ß-caryo-phyllene, and bicycloelemene. Aromatic esters were also prominent in the stem oil (10.3%). Main sesquiterpene compounds common to leaf and stem oils were bicycloelemene (13.9 and 1.0%),
ß-caryophyllene (14.6 and 6.2%), α-humulene (20.4 and 13.3%) , and bicyclogermacrene (15.4 and 9.2%), respectively.

Studies
• Antimicrobial / Essential Oil / Germacrene D / Leaves: Study evaluated the EO of three Vietnamese Annonaceae species, Meiogyne virgata, M. vietnamica, and Orophea polycarpa. Hydrodistillation and GC-FID/MS of EO yielded major compound of germacrene D (42.48%) for M. virgata. The EO of Mv leaves exhibited strong antimicrobial activity against Gm(+) Bacillus subtils ATCC 5230, Gram(-) Escherichia coli ATCC 8739, and fungus Aspergillus niger ATCC 9587 with same MIC of 16.µg/ml. Germacrene D showed binding affinity values of -66.68, -5.265, and -5.602 kcal/mol with proteins E. coli DNA gyrase, B. subtilis TasA, and A. niger PhyA. Germacrene D is predicted to have low toxicity and is not active against any of the considered target organs. (5)

Availability
