Kuntze from Dak Lak province, Vietnam JF - Academia Journal of Biology JA - AJB VL - 30 IS - 4 SE - Articles DO - 10.15625/0866-7160/v30n4.5453 UR - https://vjs.ac.vn/index.php/vjbio/article/view/5453 SP - 64-67 AB - <p><em>Anisomeles indica</em> (L.) Kuntze<em> </em>is a perennial herb, 0.70-1.20 m high. Stem is cylindrical, erect, densely hairy at the top and sides of the stem. Leaves are opposite, oval or ovate, 7-15 ยด 3-6 cm, densely pubescent on both sides. Inflorescence is in terminal spike of underneath loosely arranged whorls. Flowers are impedicellate, pink or purple. Fruits are 4-drupelets, oblong ovate. Fruiting period is from September to March.</p> <p>The yield of essential oil from leaves and fruits of <em>Anisomeles indica</em> (L.) Kuntze was 0.1 percent from air-dry material. By using GC and GC/MS analysis, 37 have been identified which accounts for more than 96.4% of the essential oil. The main constituents of essential oil were a-pinene (32.6%), limonene (26.6%), caryophyllene oxide (10.2%), b- caryophyllene (6.0%) and bornyl acetat (5.2%).</p> ER -
