Marsilea crenata is classified as hydrophytes plant growth in paddy's field, ponds, lakes, swamp or river and called semanggi as Javanese local name. The plant ethnobotanically used as food by steaming. The research was aimed to describe the histological and chemical composition of leaves and stems as well as the influence of steaming on chemical components. The result showed that the structures of stalks, stem and root were not equipped with collenchymas tissue. The cortexes consist of many aerenchym as well as the abaxial and adaxial laminas were equipped with a layer of epidermis and the stomata on the upper part of leaf. Leaves and stems contain water, ash, fat, protein, and crude fiber 89%, 2.70%, 4.35%, 2.28% (w/w), respectively. Steaming process reduced about 80% of ash content while the vitamins C, beta carotene and total carotenes content decreased about 17%, 37%, and 43%, respectively. The content of potassium as main mineral dropped 7% due to steaming process. The fresh leaves and stems of Marsilea crenata contain reducing sugar, steroid, carbohydrate, and flavonoids.

Marsilea crenata ni aina ya mimea ya hydrophytes inayokua katika mashamba ya mchele, vidimbwi, maziwa, mabwawa au mito na inaitwa semanggi kama jina la kienyeji la Kijavan. Mti ethnobotanically kutumika kama chakula kwa steaming. Utafiti huo ulikuwa na lengo la kuelezea muundo wa histolojia na kemikali ya majani na shina na pia ushawishi wa mvuke kwenye vipengele vya kemikali. Matokeo yalionyesha kwamba miundo ya shina, shina na mizizi haikuwa na tishu ya collenchymas. Cortex ni pamoja na aerenchyma nyingi, na pia laminas abaxial na adaxial walikuwa na tabaka la epidermis na stomata juu ya sehemu ya juu ya jani. Majani na shina zina maji, majivu, mafuta, protini, na nyuzi za mafuta (89%, 2.70%, 4.35%, 2.28% kwa uzito). Katika mchakato wa kuchoma, kiasi cha majivu kilipungua kwa asilimia 80 na kiasi cha vitamini C, beta-carotene na jumla ya carotene kilipungua kwa asilimia 17 na asilimia 37 na asilimia 43 kwa kila moja. Kiasi cha potasiamu katika mafuta ya mvinyo kilipungua kwa asilimia 7 kutokana na mchakato wa kuchoma. Majani na shina la Marsilea crenata lina sukari, steroidi, wanga, na flavonoidi. "Mapendekezo ya ""Marsillae crenata"" ni ya msingi na ya msingi, na inahusu: ""Machapisho ya jarida hili yanakubaliana na masharti yafuatayo: Waandishi wanahifadhi haki ya kuchapisha kwa mara ya kwanza na kutoa jarida haki ya kuchapisha kwa kazi hiyo kwa wakati mmoja chini ya leseni ya Creative Commons Attribution ambayo inaruhusu wengine kushiriki kazi hiyo na uthibitisho wa uandishi wa kazi na kuchapishwa kwa mara ya kwanza katika jarida hili." - Waandishi wanaweza kuingia katika mipango ya kikatiba ya ziada ya kutangaza toleo la kuchapishwa la jarida (kwa mfano, kuiweka kwenye hifadhi ya taasisi au kuichapisha katika kitabu), na uthibitisho wa kuchapishwa kwake kwa kwanza katika jarida hili.
