Twenty six different Bangladeshi plants of folkloric contraceptive use were screened for their oil content, percent unsaponifiables and steroids particularly estradiol, and estrogenic steroids. The distribution of these parameters were studied in seeds, roots, leaves, barks and whole plants. The oil content ranged between 0.23 and 6.75% being highest in Jasminium sacbac (family : oleaceae) seeds. The unsaponifiables varied from 0.04 to 7.87% showing highest content in Xanthium stamanium (roots), and least in Litsea sebifera (Leaves). All plants tested showed positive Salkowski test. Of all 26 plants screened, Synedrella Nodiflora (whole plant), Heliotropicum indicum (root), Belva chal (Bark) and Phyllanthus neruri (whole plant), showed high content of estradiol. Amongst these four, Heliotropicum indicum root showed highest concentration of estradiol.
对26种不同的孟加拉民间用于避孕的植物进行了筛选，检测其含油量、不皂化物百分比以及类固醇（特别是雌二醇）和雌激素类固醇的含量。研究了这些参数在种子、根、叶、树皮和整株植物中的分布情况。含油量在0.23%至6.75%之间，在素方花（家族：木犀科）种子中含量最高。不皂化物含量从0.04%至7.87%不等，在苍耳（根）中含量最高，在潺槁木姜子（叶）中含量最低。所有测试植物的萨科夫斯基试验均呈阳性。在筛选的所有26种植物中，裸柱菊（整株植物）、天芥菜（根）、白饭树（树皮）和叶下珠（整株植物）的雌二醇含量较高。在这四种植物中，天芥菜根的雌二醇浓度最高。
