|  Botany
Sampaguitang-gubat is a shrub or woody climber growing to
a height of 2 meters. Leaves are oblong-ovate, about 10 centimeters long, 5 centimeters
wide, the upper ones smaller, pointed at the apex and broadly rounded at the
base. Flowers are white and usually fragrant, borne on terminal inflorescences.
Calyx is turbinate and terminating into setose segments. Corolla is smooth,
its tube twice as long as the calyx, with oblong lobes rotately spreading.
Berries are usually ellipsoid, less than 1 centimeter long, fleshy, shiny and bluish-black
when mature.
Distribution
- Common in thickets from sea level
to an altitude of 1,500 meters, from Ilocos Sur to Sorsogon Provinces in Luzon; and in Mindoro, Cuyo, Palawan, Dumaran, Catanduanes, Leyte, Panay, Negros, Cebu, Bohol and Mindanao.
- Frequently encountered in thickets along the seashore and tidal streams.
- Also occurs in the Malay Peninsula and Archipelago.
Constituents
- Study of methanol extract yielded nine compounds viz., protocatechuic acid (1), caffeic acid (2), salicylic acid (3), isovanillic acid (4), ferulic acid (5), methyl caffeate (6), caffein (7), 3,6-diisopropyl-
piperazin-2,5-dione (8), scopoletin (9). (2)
Properties
- Considered febrifuge.
- Studies have intervention potential in ulcerative colitis.
Parts utilized
Roots and leaves.
Uses
Folkloric
- In the Philippines, root decoction used for scurvy and
as mouth wash for inflamed gums.
- Root decoction used after after childbirth.
- Infusion used for yaws.
- Root decoction used as febrifuge.
- Poultices of leaves used for headache and vertigo.

Studies
• Constituent Study: Study of methanol extract yielded 9 compounds, which were isolated from the plant for the first time. (See constituents above) (2)
• Measurement of Protocatechuic Acid: Invention discloses an accurate and quick method for measuring the content of protocatechuic acid in Jasminum elongatum. (4)
• Intervention of Ulcerative Colitis / Total Glycosides: Metabolomics study evaluated the intervention effect of total glycosides from J. elongatum in a mice model of ulcerative colitis. Results showed significant reduction of mice colonic injury, significantly (p<0.01) increased SOD activity and significantly (p<0.01) lowered MPO activity and MDA level. (5)
Availability
- Wildcrafted.
- Dried stems and leaves in the cybermarket.
