Capparis masaikai, known as mabinlang, grows in the subtropical region of the Yunnan province of China and bear fruits of tennis-ball size. The mature seeds are used in traditional Chinese medicine. They are also used as sweets; the seeds elicit a sweet taste when chewed. The origin of the sweet taste was identified as sweet-tasting proteins named mabinlins. They are highly sweet, 100-400 times sweeter than sucrose on a weight basis. References masaikai Flora of China
