dc.description.abstract | Salam (Syzygium polyanthum Wight) merupakan tumbuhan yang termasuk
ke dalam famili Myrtaceae. Salam dimanfaatkan sebagai bahan pengharum dan
penyedap makanan alami serta sebagai bahan obat diabetes, obat hipertensi, maag,
malaria dan kanker. Ekstrak daun salam mengandung senyawa metabolit berupa
alkaloid, flavonoid, fenol dan terpenoid. Penelitian ini bertujuan mempelajari
struktur anatomi, struktur sekretori dan menganalisis kandungan senyawa metabolit
yang terakumulasi dalam struktur sekretori. Struktur anatomi, struktur sekretori dan
histokimia diamati pada daun dan ranting. Salam memiliki daun hipostomata
dengan stomata tipe parasitik. Berkas pembuluh pada tulang daun utama
menyerupai bentuk hati dengan tipe kolateral tertutup, sedangkan pada ranting
berkas pembuluh bertipe bikolateral. Pada salam terdapat kristal kalsium oksalat
berbentuk drus yang tersebar di jaringan palisade daun dan empulur ranting.
Struktur sekretori berupa rongga sekretori dan sel idioblas yang terdapat pada daun
dan ranting. Rongga sekretori pada daun tersebar di antara jaringan palisade,
jaringan bunga karang dan korteks pada ranting. Sel idioblas pada daun dapat
dijumpai di antara jaringan epidermis, jaringan bunga karang, floem dan korteks
pada tulang daun. Sel idioblas juga teridentifikasi pada korteks, floem dan empulur
pada ranting. Alkaloid, terpenoid, fenol dan senyawa lipofilik terdeteksi pada
struktur sekretori seperti sel idioblas dan rongga sekretori. Selain itu, senyawa
tersebut dapat dijumpai pada jaringan umum seperti kutikula, jaringan palisade dan
pembuluh floem pada daun. Terpenoid, fenol dan senyawa lipofilik terakumulasi
pada sel idioblas, periderm dan korteks pada ranting. Flavonoid tidak terdeteksi
pada daun maupun ranting. | id |
dc.description.abstract | Salam (Syzygium polyanthum Wight) is belongs to the Myrtaceae famili.
Salam is used as a natural food flavoring agent, as well as medication for diabetes,
hypertension, ulcer, malaria and cancer. Salam leaf extract contains metabolite
compounds in the form of alkaloids, flavonoids, phenols, and terpenoids. This
research aimed to study the anatomical structure, secretory structure, and analyze
the content of metabolite compounds that accumulate in the secretory structures.
The anatomical, secretory and histochemical analyses were conducted on the leaves
and twigs. Salam had hypostomata leaves with parasitic stomata. The vascular
bundle on the leaf midrib was arranged in a heart shape with a closed collateral
type, while on the twig was a bicolateral type. Calcium oxalate crystals in the form
of drus were scattered in the palisade tissue of the leaf and pith of the twigs. The
secretory structures in the form of secretory cavities and idioblast cells were found
on leaves and twigs. Secretory cavities in the leaves were scattered among the
palisade and spongy mesophyll cells, while on the twig were found in the cortex.
Idioblast cells in leaves can be found among epidermal cells, spongy mesophyll
cells, phloem and cortex in the midrib. Idioblast cells were also identified in the
cortex, phloem and pith in the twigs. Alkaloids, terpenoids, phenols and lipophilic
compounds were detected in secretory structures i.e: idioblast cells and secretory
cavities. In addition, these compounds were also presented in other tissues including
palisade tissue, phloem vessels and cuticles on the leaves. Terpenoids, phenols and
lipophilic compounds were accumulated in idioblast cells, periderm and cortex in
the twigs. Flavonoids were not detected on both leaf and twigs. | id |
