Geographical Distributions

Peristrophe bivalvis is distributed from eastern India and Sri Lanka to central China, Taiwan, the Philippines, Malaysia, and Java. It is (or was) cultivated in India (Bengal and Assam), the southern Philippines, and, rarely, in Java. Often the plant is semicultivated, as a relic of former cultivation. [2]

Botanical Description

P. bivalvis is a member of the family Acanthaceae. It is an erect, often much-branched herb that can grow up to 1 m tall and rarely up to 1.5 m. [2]

The stems are subquadrangular. They are usually swollen above the nodes, pubescent, especially apically, or nearly smooth. [2]

The leaves are arranged opposite, membranaceous, ovate to lance-shaped or oblong, measuring 7-16 cm x 2.5-7.5 cm, wedge-shaped to rounded at the base, acuminate at apex, with entire or shallowly undulating margins, hairless above and sparingly pubescent beneath. The petiole is 0.5-3(-4) cm long. [2]

The flowers are in terminal cymes, which are composed of 1-4 involucres where each involucre is with 2-6 flowers. Two of the flowers are large and with unequal bracts. The sepal is 3-7 mm long and with ordinary glandular hairs. The petals are 3.5-5 cm long, with long tortuous tube and with two-lipped, upside-down limb, pubescent outside, and reddish-violet but sometimes pale. There are 2 stamens that are inserted near the top of the petal tube and long-exserted while the filaments are retrorsely hirsute. The 2-lobed style is slender. [2]

The fruit is a club-shaped to ellipsoid capsule, measuring 1.5-2 cm long, pubescent, and 2-valved with 2 orbicular and flat seeds per valve, which are slightly covered with warty protuberances. [2]

Cultivation

P. bivalvis is often found on cultivated lands, in thickets and coconut groves, probably often as a relic of cultivation. Under supposed natural conditions, it grows along watercourses in forests. In the Philippines, it is cultivated up to 1600 m altitude. [2]

Chemical Constituent

P. bivalvis has been reported to contain aliphatics, 14-methyltritriacont-14-en-15-ol, 35-hydroxynonatriacontanal, phenoxazine alkaloids, peristrophine, perisbivalvine. [4]

Plant Part Used

Whole plant. [5]

Traditional Use

P. bivalvis has been used in traditional medicine for the treatment of pulmonary tuberculosis, haemoptysis, bronchitis, congestion and wrench. In Thailand, this plant was also putatively considered for an inhibitor of snake venom. [5]

P. bivalvis is essentially a plant used in traditional Chinese medicine. It is believed to clear heat and resolve toxins, cool the blood and extinguish wind. It also dissipate stasis and disperse swelling. [6]

Preclinical Data

Pharmacology

Antithrombotic activity

Hemorrheological parameters (hematocrit, fribrinogen level, plasma viscosity and apparent whole blood viscosity) are primary risk factors in ischaemic heart disease. The extract from P. bivalvis showed ability to decrease effectively many hemorrheological parameters while at the same time was found to inhibit thrombus formation. [7]

Antihypertensive activity

Extract of P. bivalvis was found to have the ability to reduce high blood pressure in rats. At the same time it increases the levels of NO and NO-synthase in the serum and NO in urine. It also reduces the concentration of ET in serum and that of angiotensin II in the thoracic artery. Thus, the possible mechanism of the anti-renovascular hypertensive activity is through increasing NO in serum and decreasing angiotensin II in thoracic aorta. [8][9]

Antioxidant activity

Fresh P. bivalvis has 64% free polyphenols within its substance rendering it active as an antioxidant. It showed significant free radical scavenging activity (EC50 = 10) and LDL oxidation inhibition activity (IC50 = 34.2 [total] and 44.9 [free] too. [10]
